Artificial intelligence (AI) and machine learning (ML) offer a powerful suite of tools to accelerate climate change mitigation and adaptation across different sectors. However, the lack of high-quality, easily accessible, and standardized data often hinders the impactful use of AI/ML for climate change applications.
In this project, Climate Change AI, with the support of Google DeepMind, aims to identify and catalog critical data gaps that impede AI/ML applications in addressing climate change, and lay out pathways for filling these gaps. In particular, we identify candidate improvements to existing datasets, as well as "wishes" for new datasets whose creation would enable specific ML-for-climate use cases. We hope that researchers, practitioners, data providers, funders, policymakers, and others will join the effort to address these critical data gaps.
This project is currently in its beta phase, with ongoing improvements to content and usability. We encourage you to provide input and contributions via the routes listed below, or by emailing us at datagaps@climatechange.ai. We are grateful to the many stakeholders and interviewees who have already provided input.
Analysis of grid reliability events
Details (click to expand)
Power grid control centers receive multiple streams of data (with respect to alarms, sensors, and field reports) that are semi-structured in nature at a high volume. ML can assist in interpreting these data to better understand the sequence of events leading up to an incident as well as to identify and detect the causes behind system disturbances affecting grid reliability.
Access to EPRI10 grid alarm data is currently limited within EPRI. Data gaps with respect to usability are the result of redundancies in grid alarm codes, requiring significant preprocessing and analysis of code ids, alarm priority, location, and timestamps. Alarm codes can vary based on sensor, asset and line. Resulting actions as a consequence of alarm trigger events need field verifications to assess the presence of fault or non-fault events.

O2: Obtainability > Accessibility
Data access is limited within EPRI due to restrictions with respect to data provided by utilities.
Anonymization and aggregation of data to a benchmark or toy dataset by EPRI to the wider community can be a means of circumventing the security issues at the cost of operational context.
U1: Usability > Structure
Grid alarm codes may be non-unique for different lines and grid assets. In other words, two different codes could represent equivalent information due to differences in naming conventions requiring significant alarm data pre-processing and analysis in identifying unique labels from over 2000 code words. Additional labels expressing alarm priority, for example high alarm type indicative of events such as fire, gas, or lightning, are also encoded into the grid alarm trigger event code.
Creation of a standard structure for operational text data such as those already utilized in operational systems by companies such as General Electric or Siemens can avoid inconsistencies in data.
U3: Usability > Usage Rights
Usage rights are currently constrained to those working within EPRI at this time.
U4: Usability > Documentation
Remote signaling identification information from monitoring sensors and devices encode data with respect to the alarm trigger event in the context of fault priority. Based on the asset, line, or sensor, this identification code can vary depending on naming conventions used. Documentation on remote signal ids associated with a dictionary of finite alarm code types can facilitate pre-processing of alarm data and assessment on the diversity of fault events occurring in real-time systems (as different alarm trigger codes may correspond to redundant events similar in nature).
U5: Usability > Pre-processing
In addition to challenges with respect to the decoding of remote signal identification data, the description fields associated with alarm trigger events are unstructured and vary in the amount of text detail provided. Typically the details cover information with respect to the grid asset and its action. For example, a text description from a line monitoring device may describe the power, temperature, and the action taken in response to the grid alarm trigger event. Often in real world systems the majority of grid alarm trigger events are comprised of short circuit faults and non-fault events, limiting the diversity of fault types found in the data.
To combat these issues, data pre-processing becomes necessary. For remote signal identification data this includes parsing and hashing through text codes, assessing code components for redundancies, and building an associated reduced dictionary of alarm codes. For textual description fields, and post-fault field reports, the use of natural language processing techniques to extract key information can provide more consistency between sensor data. Additionally, techniques like diverse sampling can account for the class imbalance with respect to the associated fault that can trigger the alarm.
U6: Usability > Large Volume
Operational alarm data volume is large given the cadence of measurements made in the system at every millisecond. This can result in high data volume that is tabular in nature, but also unstructured with respect to text details associated with alarm trigger events, sensor measurements, and controller actions. Since the data also contains locations and grid asset information, spatiotemporal analysis can be made with respect to a single sensor and the conditions over which that sensor is operating. Therefore indexing and mining time series data can be an approach for facilitating faster search over alarm data leading up to a fault event. Additionally natural language processing and text mining techniques can also be utilized to facilitate search over alarm text and details.
R1: Reliability > Quality
Alarm trigger events and the corresponding action taken by the events, require post assessment by field workers especially in cases of faults or perceived faults for verification.
U2: Usability > Aggregation
Reports on location, asset, and time can result in false alarm triggers requiring operators to send field workers to investigate, fix, and recalibrate field sensors. The data with respect to field assessments can be incorporated into the data to provide greater context.
Assessing forest restoration outcomes

Efforts are being made to restore ecosystems like forests and mangroves. ML can be used to monitor biodiversity changes before and after restoration efforts, in order to quantify their effectiveness and outcomes.
There is a lack of standardized protocol to guide data collection for restoration projects, including which variables to measure and how to measure them. Developing such protocols would standardize data collection practices, enabling consistent assessment and comparison of restoration successes and failures on a global scale.

There is, in general, not a lot of datasets one can use to cover the spectrum of population, age, gender, economic, etc. To make good use of available data, there should be more efforts to integrate available data from disparate data sources, such as the creation of data repositories and the open community data standard.

Identification of individuals in wildlife (e.g., individual animals) refers to the process of recognizing and confirming the identity of an animal during subsequent encounters. It is crucial for identifying and monitoring endangered species to better understand their needs and threats, and to aid in conservation efforts. Computer vision related ML techniques are widely used for automatic individual identification.
The scarcity of publicly available and well-annotated data poses a significant challenge for applying ML in biodiversity study. Addressing this requires fostering a culture of data sharing, implementing incentives, and establishing standardized pipelines within the ecology community. Incentives such as financial rewards and recognition for data collectors are essential to encourage sharing, while standardized pipelines streamline efforts to leverage existing annotated data for training models.

S1: Sufficiency > Insufficient Volume
One of the foremost challenges is the scarcity of publicly open and adequately annotated data for model training. It is worth mentioning that the lack of annotated datasets is a common and major challenge applied to almost every modality of biodiversity data and is particularly acute for bioacoustic data, where the availability of sufficiently large and diverse datasets, encompassing a wide array of species, remains limited for model training purposes.
This scarcity of publicly open and well annotated datasets arises from the labor-intensive nature of data annotation and the dearth of expertise necessary to accurately identify species. This is the case even for relatively well-studied taxa such as birds, and is even more notable for taxa such as Orthoptera (grasshoppers and relatives). The incompleteness of our current taxonomy also compounds this issue.
Though some data cannot be shared with the public because of concerns about poaching or other legal restrictions imposed by local governments, there are still considerable sources of well-annotated data that currently reside within the confines of individual researchers’ or organizations’ hard drives. Unlocking these data will partially address the data gap.
To achieve this goal:
A concerted effort to foster a culture of data sharing at both the individual and cross-institutional levels within the ecology community is imperative.
Effective incentives, including financial rewards, funding opportunities, and incentives for publication, must be instituted to incentivize data sharing within the ecology domain. Moreover, due recognition should be accorded to data collectors, facilitated through appropriate data attribution practices and the assignment of digital object identifiers to datasets.
The establishment of standardized pipelines, protocols, and computational infrastructures is essential to streamline efforts aimed at integrating and archiving data from disparate sources.
S2: Sufficiency > Coverage
There exists a significant geographic imbalance in data collected, with insufficient representation from highly biodiverse regions. The data also does not cover a diverse spectrum of species, intertwining with taxonomy insufficiencies.
Addressing these gaps involves several strategies:
Data sharing: Unlocking existing datasets scattered across individual laboratories and organizations can partially alleviate the geographic and taxonomic gaps in data coverage.
Annotation Efforts:
Leveraging crowdsourcing platforms enables collaborative data collection and facilitates volunteer-driven annotation, playing a pivotal role in expanding annotated datasets.
Collaborating with domain experts, including ecologists and machine learning practitioners, is crucial. Incorporating local ecological knowledge, particularly from indigenous communities in target regions, enriches data annotation efforts.
Developing AI-powered methods for automatic cataloging, searching, and data conversion is imperative to streamline data processing and extract relevant information efficiently.
Data Collection:
Prioritize continuous data collection efforts, especially in underrepresented regions and for less documented species and taxonomic groups.
Explore innovative approaches like Automated Multisensor Stations for Monitoring of Species Diversity (AMMODs) to enhance data collection capabilities.
Strategically plan data collection initiatives to target species at risk of extinction, ensuring data capture before irreversible loss occurs.

Bias-correction of climate projections
Details (click to expand)
Climate projection provides essential information about future climate conditions, guiding efforts in mitigation and adaptation, such as disaster risk assessments and power grid optimization. ML enhances the accuracy of these projections by bias-correcting forecasts generated by physics-based climate models (e.g., CMIP6). ML achieves this by learning the relationship between historical climate simulations (e.g., CMIP6 data) and observed ground truth data (such as ERA5 or weather station observations).
The large uncertainties in future climate projection is a big problem of CMIP6. The large volume of data and the lack of uniform structure—such as inconsistent variable names, data formats, and resolutions across different CMIP6 models—make it challenging to utilize data from multiple models effectively.

ERA5 is often used as “ground truth” in bias-correction tasks, but it has its own biases and uncertainties. ERA5 is derived from observations combined with physics-based models to estimate conditions in areas with sparse observational data. Consequently, biases in ERA5 can stem from the limitations of these physics-based models. It is worth noting that precipitation and cloud-related fields in ERA5 are less accurate compared to other fields and are not suitable for validating ML models. A higher-fidelity atmospheric dataset, such as an enhanced version of ERA5, is greatly needed. Machine learning can play a significant role in this area by improving the assimilation of atmospheric observation data from various sources.

Downloading ERA5 data from the Copernicus Climate Data Store can be very time-consuming, taking anywhere from days to months. This delay is due to the large size of the dataset, which results from its high spatio-temporal resolution, its high demand, and the fact that the data is stored on tape.
U6: Usability > Large Volume
The large volume of data poses significant challenges for downloading, transferring, storing, and processing with standard computational infrastructure. Although cloud-based access is available from various providers, it often comes with high costs and is not free. To address these challenges, it would be beneficial to make additional computational resources available alongside the storage of data.
R1: Reliability > Quality
ERA5 is often used as “ground truth” in bias-correction tasks, but it has its own biases and uncertainties. ERA5 is derived from observations combined with physics-based models to estimate conditions in areas with sparse observational data. Consequently, biases in ERA5 can stem from the limitations of these physics-based models. It is worth noting that precipitation and cloud-related fields in ERA5 are less accurate compared to other fields and are not suitable for validating ML models. A higher-fidelity atmospheric dataset, such as an enhanced version of ERA5, is greatly needed. Machine learning can play a significant role in this area by improving the assimilation of atmospheric observation data from various sources.
Extremely high-resolution simulations, such as large-eddy simulations, are needed. By explicitly resolving processes that are not resolved in current climate models, these simulations may serve as better ground truth for training machine learning models that emulate the physical processes and offer a more accurate basis for understanding and predicting climate phenomena.

The resolution of current high-resolution simulations is still insufficient for resolving many physical processes, such as turbulence. To address this, extremely high-resolution simulations, like large-eddy simulations (with sub-kilometer or even tens of meter resolution), are needed. By explicitly resolving those turbulent processes, these simulations represent a more realistic realization of the atmosphere and therefore theoretically give better model results. These simulations may serve as ground truth for training machine learning models and offer a more accurate basis for understanding and predicting climate phenomena. Long-term climate simulations at this ultra-high resolution would significantly enhance both hybrid climate modeling and climate emulation, providing deeper insights into global warming scenarios.
Given the high computational cost of running such simulations, creating and sharing benchmark datasets based on these simulations is essential for the research community. This would facilitate model development and validation, promoting more accurate and efficient climate studies.
Though a lot of data is available, a set of regularly gridded 3D high-resolution observations of the atmosphere state (like a higher-resolution version of ERA5) is still needed. This is essential for both an improved understanding of the atmospheric processes and the development of ML-based weather forecast models and climate models.

Modeling digital representations of environmental conditions and habitats using remote sensing data, such as satellite images, is crucial for understanding how environmental factors impact animal behavior and conservation efforts. This approach provides valuable insights into habitat conditions and changes, which are essential for effective wildlife conservation and management. ML can enhance this process by efficiently processing large volumes of data from various sources, leading to more detailed and accurate environmental reconstructions.
The scarcity of publicly available and well-annotated data poses a significant challenge for applying ML in biodiversity study. Addressing this requires fostering a culture of data sharing, implementing incentives, and establishing standardized pipelines within the ecology community. Incentives such as financial rewards and recognition for data collectors are essential to encourage sharing, while standardized pipelines streamline efforts to leverage existing annotated data for training models.

Data Gap Details
S1: Sufficiency > Insufficient Volume
One of the foremost challenges is the scarcity of publicly open and adequately annotated data for model training. It is worth mentioning that the lack of annotated datasets is a common and major challenge applied to almost every modality of biodiversity data and is particularly acute for bioacoustic data, where the availability of sufficiently large and diverse datasets, encompassing a wide array of species, remains limited for model training purposes.
This scarcity of publicly open and well annotated datasets arises from the labor-intensive nature of data annotation and the dearth of expertise necessary to accurately identify species. This is the case even for relatively well-studied taxa such as birds, and is even more notable for taxa such as Orthoptera (grasshoppers and relatives). The incompleteness of our current taxonomy also compounds this issue.
Though some data cannot be shared with the public because of concerns about poaching or other legal restrictions imposed by local governments, there are still considerable sources of well-annotated data that currently reside within the confines of individual researchers’ or organizations’ hard drives. Unlocking these data will partially address the data gap.
To achieve this goal:
A concerted effort to foster a culture of data sharing at both the individual and cross-institutional levels within the ecology community is imperative.
Effective incentives, including financial rewards, funding opportunities, and incentives for publication, must be instituted to incentivize data sharing within the ecology domain. Moreover, due recognition should be accorded to data collectors, facilitated through appropriate data attribution practices and the assignment of digital object identifiers to datasets.
The establishment of standardized pipelines, protocols, and computational infrastructures is essential to streamline efforts aimed at integrating and archiving data from disparate sources.
S2: Sufficiency > Coverage
There exists a significant geographic imbalance in data collected, with insufficient representation from highly biodiverse regions. The data also does not cover a diverse spectrum of species, intertwining with taxonomy insufficiencies.
Addressing these gaps involves several strategies:
Data sharing: Unlocking existing datasets scattered across individual laboratories and organizations can partially alleviate the geographic and taxonomic gaps in data coverage.
Annotation Efforts:
Leveraging crowdsourcing platforms enables collaborative data collection and facilitates volunteer-driven annotation, playing a pivotal role in expanding annotated datasets.
Collaborating with domain experts, including ecologists and machine learning practitioners, is crucial. Incorporating local ecological knowledge, particularly from indigenous communities in target regions, enriches data annotation efforts.
Developing AI-powered methods for automatic cataloging, searching, and data conversion is imperative to streamline data processing and extract relevant information efficiently.
Data Collection:
Prioritize continuous data collection efforts, especially in underrepresented regions and for less documented species and taxonomic groups.
Explore innovative approaches like Automated Multisensor Stations for Monitoring of Species Diversity (AMMODs) to enhance data collection capabilities.
Strategically plan data collection initiatives to target species at risk of extinction, ensuring data capture before irreversible loss occurs.
U2: Usability > Aggregation
A lot of well-annotated datasets are currently scattered within the confines of individual researchers’ or organizations’ hard drives.

There is no single unified data source for many socio-economic data, e.g. population, human settlement. Each organization and company comes up with its own dataset and they all differ from each other by a lot. Data validation (e.g. talk to the government and ask for more information) is needed before using the data, but it is hard to do this validation at scalable way because of the time, financial, and technical efforts required.
To improve the reliability and usability of data, data entry methods need to be standardized and automated, and a unified platform for data entry is also wished for.

Distribution-side hosting capacity estimation
Details (click to expand)
The hosting capacity of a distribution-level substation feeder on a power grid is crucial because it determines the amount of distributed energy resources (DERs) that a distribution circuit can safely accommodate without compromising grid reliability. Distribution-level substation feeders are especially susceptible to voltage fluctuations caused by solar PV generation. Operationally, distribution level substation feeders must surmount voltage sags or fault ride-through to ensure generating sources stay connected without incurring major generation loss even if disconnected for short time frames or maintained as reactive power. This may be achieved with the use of inverter technology to modulate output to match the larger power system’s needs and protect it from faults and overloads.
While OpenDSS and GridLab-D are free to use as an alternative when real distribution substation circuit feeder data is unavailable, to perform site-specific or scenario studies, data from different sources may be needed to verify simulation results. Actual hosting capacity may vary from simulation results due to differences in load, environmental conditions, and the level of DER penetration.

The sheer volume of data now poses one of the biggest challenges for satellite imagery. When data reaches the terabyte scale, downloading, transferring, and hosting become extremely difficult. Those who create these datasets often lack the storage capacity to share the data. This challenge can potentially be addressed by one or more of the following strategies:
Data compression: Compress the data while retaining lower-dimensional information.
Lightweight models: Build models with fewer features selected through feature extraction. A successful example can be found here.
Large foundation model for remote sensing data: Purposefully construct large models (e.g., foundation models) that can handle vast amounts of data. This requires changes in research architecture, such as preprocessing architecture modifications.

Very high-resolution satellite images (e.g., finer than 10 meters) typically come from commercial satellites and are not publicly available. This is particularly challenging for the Global South. One exception is the NICFI dataset, which offers high-resolution, analysis-ready mosaics of the world’s tropics.
U5: Usability > Pre-processing
Satellite images often contain a lot of redundant information, such as large amounts of data over the ocean that do not always contain useful information. It is usually necessary to filter out some of this data during model training
U2: Usability > Aggregation
Due to differences in orbits, instruments, and sensors, imagery from different satellites can vary in projection, temporal and spatial zones, and cloud blockage, each with its own pros and cons. To overcome data gaps (e.g. cloud blocking) or errors, multiple satellite images are often assimilated. Harmonizing these differences is challenging, and sometimes arbitrary decisions must be made.
U5: Usability > Pre-processing
The lack of annotated data presents another major challenge for satellite imagery. It is suggested that collaboration and coordination at the sector level should be organized to facilitate annotation efforts across multiple sectors and use cases. Additionally, the granularity of annotations needs to be increased. For example, specifying crop types instead of just “crops” and detailing flood damage levels rather than general “damaged” are necessary for more precise analysis.

Extreme heat is becoming more common in a changing climate, but predicting and accurately modeling extreme heat is difficult. ML can help by improving extreme heat prediction.
The major change involves managing the size of the data. While cloud platforms offer convenience, they come with costs. Additionally, handling large datasets requires specific techniques, such as distributed computing and occasionally large-memory computing nodes (for certain statistics).
Fault detection in low voltage distribution grids
Details (click to expand)
The low voltage distribution portion of the grid directly supplies power to consumers. As consumers integrate more distributed energy resources (DERs) and dynamic loads (such as electric vehicles), low voltage distribution systems are susceptible to power quality issues that can affect the stability and reliability of the grid. Fault inducing harmonics can be challenging to monitor, diagnose, and control due to the number of nodes/buses that connect various grid assets and the short distances between them. As load and generation change rapidly throughout the day, advanced monitoring systems become essential in detecting and localizing faults so adaptive protection and network reconfiguration efforts can be made to ensure reliability and stability.
For effective fault localization using µPMU data, it is crucial that distribution circuit models supplied by utility partners are accurate, though they often lack detailed phase identification and impedance values, leading to imprecise fault localization and time series contextualization. Noise and errors from transformers can degrade µPMU measurement accuracy. Integrating additional sensor data affects data quality and management due to high sampling rates and substantial data volumes, necessitating automated analysis strategies. Cross-verifying µPMU time series data, especially around fault occurrences, with other data sources is essential due to the continuous nature of µPMU data capture. Additionally, µPMU installations can be costly, limiting deployments to pilot projects over a small network. Furthermore, latencies in the monitoring system due to communication and computational delays challenge real-time data processing and analysis.

For µPMU data to be utilized for fault localization, the distribution circuit model must be provided by the partnering utility. Typically the distribution circuit lacks notation with respect to the phase identification and impedance values, often providing rough approximations which can ultimately influence the accuracy of localization as well as time series contextualization of a fault. Decreased accuracy of localization can then affect downstream control mechanisms to ensure operational reliability.
U5: Usability > Pre-processing
µPMU data is sensitive to noise especially from geomagnetic storms which can induce electric currents in the atmosphere and impacting measurement accuracy. They can also be compromised by errors introduced by current an potential transformers.
Depending on whether additional data from other sensors or field reports is being used to classify µPMU time series data, creation of a joint sensor dataset can influence quality based on the overall sampling rate and format of the additional non-µPMU data.
U6: Usability > Large Volume
Due to the high sampling rates, data volume from each individual µPMU can be challenging to manage and analyze due to its continuous nature. Coupled with the number of µPMUs required to monitor a portion of the distribution network, the amount of data can easily exceed terabytes. Automation of indexing and mining time series by transient characteristics can facilitate domain specialist verification efforts.
R1: Reliability > Quality
Since µPMU data is continously captured, time series data leading up to or even identifying a fault or potential fault requires verification from other data sources.
Digital Fault Recorders (DFRs) capture high resolution event driven data such as disturbances due to faults, switching and transients. They are able to detect rapid events like lightning strikes and breaker trips while also recording the current and voltage magnitude with respect to time. Additionally, system dynamics over a longer period following a disturbance can also be captured. When used in conjunction with µPMU data, DFR data can assist in verifying significant transients found in the µPMU data which can facilitate improved analysis of both signals leading up to and after an event from the perspective of distribution-side state.
S2: Sufficiency > Coverage
Currently µPMU installation to existing distribution grids have significant financial costs so most deployments have been in the form of pilot projects with utilities. Pilot studies include the Flexgrid testing facility at Lawrence Berkeley National Laboratory (LBNL), Philadelphia Navy Yard microgrid (2016-2017), the micro-synchrophasors for distribution systems plus-up project (2016-2018), resilient electricity grids in the Philippines (2016), the GMLC 1.2.5- sensing and measurement strategy (2016), the bi-national laboratory for the intelligent management of energy sustainability and technology education in Mexico City (2017-2018) based on North American Synchrophasor Initiative (NASPI) reports.
Coverage is also limited by acceptance to this technology due to a pre-existing reliance on SCADA systems which measure grid conditions on a 15 minute cadence. As transients become more common, especially on the low voltage distribution grid, transition to monitoring with higher resolution will become necessary.
S4: Sufficiency > Timeliness
µPMU data can suffer from multiple latencies within the monitoring system of the grid that are unable to keep up with the high sampling rate of the continuous measurements that µPMUs generate. Latencies occur in the context of the system communications surrounding signals as they are being recorded, processed, sent, and received. This can be due to the communication medium used, cable distance, amount of processing, and computational delay. More specifically, the named latencies are measurement, transmission, channel, receiver, and algorithm related.
Utilization of computer vision for right of way (RoW) transmission line clearance detection to identify areas where vegetation and other objects are in close proximity to towers, lines, and other grid assets which may increase fire risk.
Grid inspection robot imagery may require coordination efforts with local utilities to gain access over multiple robot trips, image preprocessing to remove ambient artifacts, position and location calibration, as well as limitations in the identification of degradation patterns based on the resolution of the robot mounted camera.

Unmanned aerial vehicle (UAV) or drone imagery for vegetation management near transmission and distribution lines may require partnerships with private companies and utilities for access and usage. LiDAR data is sparse and may partially scan power transmission lines resulting in poor data quality.

Improving power grid optimization
Details (click to expand)
Traditionally optimal power flow (OPF) seeks to solve the objective of minimizing the cost of power generation to meet a given load (economic dispatch) such that line limits due to thermal, voltage, or stability along with generation limits are met while maintaining power balance at each bus in the transmission system. Traditional techniques formulate OPF as a non-linear, constrained, non-convex optimization problem which can be solved for AC and DC systems separately. Traditional OPF solvers use a linear program to determine generation needed to minimize cost and satisfy load demand while adhering to physical constraints of the system. However, as the grid integrates more renewable generation sources there are trends towards the development of hybrid AC/DC power grids to address the limitations of traditional AC transmission systems and the desire to access remote renewables. Such hybrid systems present new challenges to traditional OPF by enabling bidirectional power flow, requiring the adaptation of OPF objective function and constraints to account for new losses, increased costs and congestion. ML can be used to approximate OPF problems, in order to allow them to be solved at greater speed, scale, and fidelity.
Grid2Op is a reinforcement learning framework that builds an environment based on topologies, selected grid observations, a selected reward function, and selected actions for an agent to select from. The framework relies on control laws rather than direct system observations which are subject to multiple constraints and changing load demand. Time steps representing 5minutes are unable to capture complex transients and can limit the effectiveness of certain actions within the action space over others. Furthermore, customization of the Grid2Op can be challenging as the platform does not allow for single to multiagent conversion, and is not a suitable environment for cascading failure scenarios due to game over rules.

U4: Usability > Documentation
In the customization of the reward function, there are several TODOs in place concerning the units and attributes of the reward function related to redispatching. Documentation and code comments can sometimes provide conflicting information. Modularity of reward, adversary, action, environment, and backend are nonintuitive requiring pregenerated dictionaries rather than dynamic inputs or conversion from single agent to multiagent functionality.
U5: Usability > Pre-processing
The game over rules and constraints are difficult to adapt when customizing the environment for cascading failure scenarios that may be interesting to conduct for more complex adversaries such as natural disasters. Code base variations between versions especially between the native and Gym formated framework lose features present in the legacy version including topology graphics.
S2: Sufficiency > Coverage
Coverage is limited to the network topologies provided by the grid2op environment which is based on different IEEE bus topologies. While customization of the environment in terms of the “Backend,” “Parameters,” and “Rules” are possible, there may be dependent modules that may still enforce game-over rules. Furthermore, since backend modeling is not the focus of grid2op, verification that customization obeys physical laws or models is necessary.
S3: Sufficiency > Granularity
The time resolution of 5-minute increments may not represent realistic observation time series grid data or chronics. Furthermore, the granularity may limit the effectiveness of specific actions in the provided action space. For example, the use of energy storage devices in the presence of overvoltage has little effect on energy absorption incentivizing the agent to select from grid topology actions such as line changing line status or changing bus rather than setting storage.
R1: Reliability > Quality
The grid2op framework relies on mathematical robust control laws and rewards which train the RL agent based on set observation assumptions rather than actual system dynamics which are susceptible to noise, uncertainty, and disturbances not represented in the simulation environment. It has no internal modeling of the equations of the grids, or what kind of solver that needs to be adopted to solve traditional nonlinear optimal power flow equations. Specifics concerning modeling and preferred solver require users to customize or create a new “Backend.” Additionally, such RL human-in-the-loop systems in practice require trustworthiness and quantification of risk.
Traditional OPF simulation software depending on whether it is open source, may require the purchase of licenses for advanced features and functionalities. To simulate more complex systems or regions additional data regarding energy infrastructure, region-specific load demand, and renewable generation may be needed to conduct studies. OPF simulation output would require verification and performance evaluation to assess results in practice. Increasing the granularity of the simulation model by increasing the number of buses, limits, or additional parameters increases the complexity of the OPF problem, thereby increasing the computational time and resources required.

In PowerWorld, bus topologies available may be simplified representations of actual grids to simplify the modeling and simulation techniques to represent overall system behavior. MATPOWER requires the user to define the bus matrix. As the number of buses in a power system increases the computational complexity of OPF increases requiring more resources and time to solve. Additional parameters such as line limits, number of generating sources, number of DERs, and load demand also increase the complexity of the model as more constraints and assets are introduced.

A lot of ocean data is collected, but a persistent challenge is ensuring that this data is shared and utilized by those who need it. Currently, much of the data remains siloed within individual institutions, making it difficult to access for collaborative purposes. Despite numerous initiatives, such as Ocean Biodiversity Information System (OBIS), Integrated Ocean Observing System (IOOS), and others, data accessibility continues to be the biggest hurdle.

There are massive gaps in the coverage of ocean biodiversity data, with only about 7% of the upper 5 meters of the ocean being regularly monitored, and 30-60% of ocean life still unknown to science. The data is also heavily biased towards coastal regions, with much less coverage of the open ocean.
While collecting data from the deep ocean is technologically challenging, the primary issue is the lack of financial incentives. High seas fall outside national jurisdictions, so data collection often occurs only through mining companies, military operations, or ad hoc research expeditions. The absence of marine protected areas on high seas and the migratory nature of species like phytoplankton further complicate data collection. Financial tools or regulations could incentivize data collection.
Only data from 2019 to March 2022 is publicly available. Registration is required to access the data.

Non-intrusive electricity load monitoring

Non-intrusive load monitoring (NILM) is a strategy to disaggregate the total energy consumption profile into individual appliance load profiles for a building. This strategy can provide a insight to individual consumer behavior for real-time pricing, target customers who may be due for an appliance upgrade, and enable building energy management systems (EMS) to enact demand response strategies such as load shifting for sheddable or curtailable loads. These strategies are significant in reducing peaks in demand thereby maintaining grid stability.
Pecan Street DataPort requires non-academic and academic users to purchase access via licensing and number of building data features requested.

The Pecan street dataset represents the same type of modern planned building with similar floor plans and little variations with respect to other buildings. In the initial dataset covering the Mueller community in Austin, Texas, it is important to note that the community began development following 1999 which may not be a representative sample of older buildings which are more likely to require upgrades to energy efficient appliances and systems.
Additionally the dataset primarily covers Texas which is supplied by ERCOT, and has some limited coverage in New York, California, and is growing to include Puerto Reco depending on volunteer participation. This could introduce self-selection bias, as households who participate are already interested in energy saving.
Enrollment of older built environment homes and different temperate regions within the United States and globally, may provide greater insight into household engagement with energy consumption behavior and efficiency monitoring.

The data does not track real-time occupancy of individuals in the household which may provide insight into behavioral effects on energy consumption. Addition of this data, can also allow for improved customer segmentation models based on consumption, as patterns can change with respect to time and day of the week. The data would also be amenable for consumer-in-the-loop energy management studies with respect to comfort based on customer habitual activity, location in the house, and number of occupants.

Sub-metered data relies on the sensor network installation made in the building. Depending on the technology used, some sensors required calibration or were prone to malfunctions and delays. Additionally, interference from other devices could also be present in the aggregate building level readings, such as that experienced by REFIT, that needed to be addressed manually to enhance the usability of the dataset.
R1: Reliability > Quality
In the AMPds2 data the sum of the sub-metered consumption data did not add up to the whole house consumption due to some rounding error in the meter measurements.
Datasets that required self-reporting may introduce participant bias as the resolution with which households update occupancy information may vary. Additionally, consumption behaviors in volunteer households may have a pre-existing propensity for energy efficient actions based on enthusiasm for study participation and therefore not representative of the general population. For example, in UK-DALE, participants were comprised of masters and PhD graduate students from Imperial College which may have energy usage patterns and behaviors that are not representative of the general population.
S2: Sufficiency > Coverage
In AMPds2 data there were some missing data from electricity and water and natural gas readings. Additionally, there existed un-metered household loads which were not accounted for in the whole house reading and dishwasher consumption did not have a direct water meter for monitoring. REFIT also did not monitor appliances that could not be connected to individual appliance monitors such as electric ovens. Depending on the built environment, even with the use of external plugload sensors for disaggregated load consumption, some larger loads may not be able to be connected to building level meters. For example, in the GREEND dataset, electric boilers in Austria were connected to separate meters. In the UMass smart home dataset, gas furnaces, exahust fans, and recirculator pump loads were not able to be monitored.
AMPds2, DEDDIAG, DRED, iAWE, REDD, REFIT, and UMass smart home dataset all gather data in single family homes which may not be representative of the diversity of buildings in terms of age, location, construction, and potential household demographics. REFIT data covers different single family home types such as detached, semi-detached, and mid-terrace homes that ranged from 2-6 bedrooms with builds from the 1850s to 2005. GREEND covers apartments in addition to single family homes but the number of households was 9. AMPds2, DRED, iAWE only cover a single household. Additionally, datasets are specific to the location where the measurements were taken which are susceptible to the environmental conditions of the region as well as the culture of the population. For example, REDD consists of data from 10 monitored homes which may not be representative of common appliances contributing to the overall load of the broader population outside of Boston.
COMBED contains complex load types that may rely on variable-speed drives as well as multi-state devices, which the other datasets do not contain which may be due to the difference in building type but could also be due to the lack of diversity of appliance representation.
ECO data relied on smart plugs for disaggregated load consumption measurements which varied between households depending on the smart plug appliance coverage. For all households the total consumption was not equal to the sum of the consumption measured from the plugs alone, indicative of a high proportion of non-attributed consumption.
S6: Sufficiency > Missing Components
All datasets mentioned do not include electric vehicle loads. REDD, AMPds2, COMBED, DEDDIAG, DRED, GREEND, iAWE, UK-DALE do not include generation from rooftop solar. REFIT contains solar from three homes but they were not the focus of the study and were treated as solar interference to the aggregate load. The UMass smart home dataset only had representation of one home with solar and wind generation, though at a significantly larger square footage and build compared to the other two homes that were featured.
While DRED provided occupancy information through data collected from wearable devices with respect to the home and ECO and IDEAL through self-reporting and an infrared entryway sensor, all other studies did not.
The majority of datasets are not amenable to human in the loop user behavior analysis with respect to consumption patterns, response to feedback, and the effectiveness in load shifting to promote energy conserving behaviors due to their lack of representation.
While AMPds2 includes some utility data, most datasets do not incorporate billing or real time pricing. This type of data would be beneficial as it varies from time, season, region, and utility.
Battery storage was not taken into account in all building consumption datasets.

Long-term wind forecasting can allow for resource assessment studies for offshore energy production, wind resource mapping, and wind farm modeling.
Due to the location, FINO platform sensors are prone to failures of measurement sensors due to adverse outdoor conditions such as high wind and high waves. Often when sensors fail manual recalibration or repair is nontrivial requiring weather conditions to be amenable for human intervention. This can directly affect the data quality which can last for several weeks to a season. Coverage is also constrained to the platform and associated wind farm location.

U5: Usability > Pre-processing
The dataset is prone to failures of measurement sensors. Issues with data loggers, power supplies, and effects of adverse conditions such as low aerosol concentrations can influence data quality. High wind and wave conditions impact the ability to correct or recalibrate sensors creating data gaps that can last for several weeks or seasons.
S2: Sufficiency > Coverage
Coverage of wind farms is relegated to the dimensions of the platform itself and the wind farm that it is built in proximity to. For locations with different offshore characteristics similar testbed platforms or buoys can be developed.
S5: Sufficiency > Proxy
Due to the nature of sensors exposed to environmental ocean conditions and storms, often FINO sensors may need maintenance and repair but are difficult to physically access. Gaps in the data from lack of data points can be addressed by utilizing mesoscale wind modeling output.
Spatiotemporal coverage of the offshore meteorological and windspeed platform data is restricted to the dimensions of the platform itself as well as the time of construction. Depending on the data provider access to the data may require the signing of a non-disclosure agreement.

Short-term wind forecasting can enable estimation of active power generated by wind farms in the absence of curtailment.
Data obtainability is achieved by requesting access via the Orsted form. Sufficiency of the dataset is constrained by volume where only a finite amount of short term off-shore wind farms exist to which expanding the coverage area, volume and time granularity of data to under 10 minutes may enable transient detection from generated active power.

Post-disaster damage assessment
Details (click to expand)
Post-disaster evaluations are crucial for identifying vulnerabilities exposed by climate-related events, which is essential for enhancing resilience and informing climate adaptation strategies. ML can help by rapidly identifying and quantifying damage, such as structural collapse or vegetation loss, thereby improving response and recovery efforts.
Financial loss data is typically proprietary and held by insurance and reinsurance companies, as well as financial and risk management firms. Some of the data should be made available for research purposes.
The resolution of publicly available datasets is insufficient for accurate damage assessments. To improve this, some commercial high-resolution images should be made accessible for research purposes.

Short-term electricity load forecasting
Details (click to expand)
Short-term load forecasting (STLF) is critical for utilities to balance demand with supply. Utilities need accurate forecasts (e.g. on the scale of hours, days, weeks, up to a month) to plan, schedule, and dispatch energy while decreasing costs and avoiding service interruptions. Furthermore, for grids that may have portions privatized, utilities rely on forecasts to procure (e.g. source and purchase) energy to meet demands. In peak conditions, where loads have been underestimated, utilities have limited options. One option is to utilize reserve capacity, or additional electric supply to ensure reliable power to customers. This usually entails recruitment of expensive peaker plants dependent on fossil-fuels in city centers to meet immediate demands over short distances. Another option is for the utility to initiate an outage to clip peaks. In the worst case, grid assets can be overloaded resulting in system failure and unplanned blackouts. Due to the reliance of historical electricity load data, weather forecasts, time with respect to the day, week, or month, and continuous streams of advanced metering infrastructure (AMI) data, machine learning models are well suited to handle large amounts of data and capture non-linearities which traditional linear models may struggle with.
AMI data is challenging to obtain without pilot study partnerships with utilities since data collection on individual building consumer behavior can infringe upon customer privacy especially at the residential level. Granularity of time series data can also vary depending on the level of access to the data whether it be aggregated and anonymized or based on the resolution of readings and system. Additionally, coverage of data will be limited to utility pilot test service areas thereby restricting the scope and scale of demand studies.

Access to real AMI data can be difficult to obtain due to privacy concerns. Even when partnered with a utility, the AMI data can undergo anonymization and aggregation to protect individual customers. Some ISOs are able to provide data provided that a written records request is submitted. If requesting personal consumption data, tiered pricing enrollment, for example time of use, may limit temporal resolution of data that utility can provide based on system. Open datasets, on the other hand may only be available for academic research or teaching use (ISSDA CER data).
U2: Usability > Aggregation
AMI data when used jointly with other data that may influence demand such as weather data, availability of rooftop solar, presence of electric vehicles, building specifications, and appliance inventory may require significant additional data collection or retrieval.
U3: Usability > Usage Rights
For ISSDA CER data use, a request form must be submitted for evaluation by issda@ucd.ie. For data obtained through utility collaborative partnerships, usage rights may vary.
U5: Usability > Pre-processing
Data cleanliness may vary depending on the data source. For individual private data collection through testbed development, cleanliness can depend on formats of data stream output from the sensor network system installed.

With respect to the CER Smart Metering Project and the associated Customer Behavior Trials (CBT), Electric Ireland and Bord Gais Energy smart meter installation and monitoring occurred from 2009-2010. This anonymized dataset may no longer be representative of current behavior usage as household compositions and associated loads change with time. Similarly, pilot programs through participating utilities are finite in nature.
Faraday synthetic AMI data is a response to the bottlenecks faced in retrieval of building level demand data based on consumer privacy. However, despite the model being trained on actual AMI data, synthetic data generation requires a priori knowledge with respect to building type, efficiency, and presence of low carbon technology. Furthermore, since the dataset is trained on UK building data, AMI time series generated may not be an accurate representation of load demand in regions outside the UK. Finally, since data is synthetically generated studies will require validation and verification using real data or aggregated per substation level data to assess its effectiveness.

Faraday is currently accessible through Centre for Net Zero’s API.
The Variational Autoencoder Model can generate synthetic AMI data based on several conditions. The presence of low carbon technology (LCT) for a given household or property type depends on access to battery storage solutions, solar rooftop panels, and presence of electric vehicles. This type of data may require curation of LCT purchases by type and household. Building type and efficiency at the residential and commercial/industrial level may also be difficult to access requiring the user to set initial assumptions or seek additional datasets. Furthermore, data verification requires a performance metric based in actual readings. This may be done through access to substation level load demand data.
U3: Usability > Usage Rights
Faraday is open for alpha testing by request only.
R1: Reliability > Quality
Verification of AMI synthetic data requires verification which can be done in a bottom up grid modeling manner. For example, load demand at the substation level can be estimated based on the sum of individual building loads which the substation services. This value can then be compared to the actual substation load demand provided through a private partnerships with distribution network operators (DNOs). However, accuracy of a specific demand profile per property or section of properties would require identification of a population of buildings, a connected real-world substation, and residential low carbon technology investment for the set of properties under study.
S2: Sufficiency > Coverage
Faraday is trained from utility provided AMI data from the UK which may not be representative of load demand and corresponding building type and temperate zone of other global regions.
Coverage of data is restricted to the pilot test bed whether it be through private collection, partnership with the utility, or use of pre-existing demand data.
S3: Sufficiency > Granularity
Data granularity is limited to the granularity of data the model was trained on.
S4: Sufficiency > Timeliness
Timeliness of dataset would require continuous integration and development of the model using MLOps best practices to avoid data and model drift.

Smart inverter management for distributed energy resources
Details (click to expand)
Distributed energy resources (DERs) such as solar photovoltaics and energy storage systems are a part of low-inertia power systems that do not rely on traditional rotating components. These DERs rely on distributed inverters to convert power from DC to AC which typically are configured to unity power factor. An alternative to unity power factor, inverters can be “smart” by dynamically managing effects of intermittancy prior to feeding power back to feeder circuits at the distribution substation level. Smart inverters can perform Volt-VAR (Voltage-VAR) and Volt-Watt (Voltage-Watt) operations, which involve adjusting the output voltage and frequency of the inverter to maintain grid stability. In other words, the DER inverter is controlled to dynamically adjust reactive power injection back into the grid. This is crucial for preventing voltage sags and swells that can occur due to the integration of DERs into the grid.
There is a need to enhance existing simulation tools to study inverter-based power systems rather than traditional machine-based based. Simulations should be able to represent a large number of distribution-connected inverters that incorporate DER models with the larger power system. Uncertainty surrounding model outputs will require verification and testing. Furthermore, accessibility to simulations and hardware in the loop facilities and systems requires user access proposal submission for NREL’s Energy Systems Integration Facility access. Similar testing laboratories may require access requests and funding.

The optimization routine of the simulation model may face challenges in determining the precise balance between grid operation criteria and impacts on customer PV generation. Generation may still require curtailment by the utility to prioritize grid stability. To circumvent this gap external data on distribution side operating conditions, load demand, solar generation, and utility-initiated generation curtailment can be collected and introduced into expanded simulation studies.
Smart inverter operational data is not publicly available and requires partnerships with research labs, utilities, and smart inverter manufacturers. However, the California Energy Commission maintains a database of UL 1741-SB compliant manufacturers and smart inverter models that can then be contacted for research partnerships. In terms of coverage area, while California and Hawaii are now moving towards standardizing smart inverter technology in their power systems, other regions outside of the United States may locate similar manufacturers through partnerships and collaborations.

Depending on the region of interest, data can be retrieved from different open data satellites that are both geostationary as well as swath which may differ in spatial and temporal resolutions and coverage area. Additionally, multispectra data may have challenges with respect to preprocessing and preparing the data for analysis. Specifically for medium term solar forecasting, actual ground irradiance may differ from approximations made by models that utilize satellite derived cloud cover products. This is because different cloud types can have different impacts on irradiance. Supplementation with ground based measurements for verification and improvements in granularity are suggested solutions.

In fact, of the 2018 countries represented, the system measurements vary from one system per country to 43,665 systems per country. Systems in Germany, the Netherlands, and Australia have more PV system testbeds than other global regions. Furthermore, depending on the testbed system selected some may have additional information on battery storage though inconsistent throughout most testbeds. This gap can be addressed by increasing the amount of private user contributed system data from diverse regions to supplement those already curated by SMA.
While SOLETE is advantageous to use for joint wind solar DER forecasting at the inverter level generation studies, the dataset can be improved by addressing several gaps in data sufficiency, namely expansion of the temporal coverage to include seasonal variations which may be addressed with additional outside data or simulation. Outside data or simulation may also improve scaling of the study to address multiple generation sources (more than one PV array and wind turbine) and the coordination between them to maintain grid reliability and stability. Additionally, a data wish for SOLETE includes the addition of maintenance schedules or system downtime data to more realistically model system dynamics with DERs.

Very-short-term solar power forecasting is critical for time series irradiance forecasting and solar ramp event identification. Solar irradiance ramp events can be defined as sudden changes in solar irradiance within a short time interval. These events are often caused by transient clouds that can lead to abrupt fluctuations in the incoming solar energy. Cloud analysis using cloud segmentation and classification as a proxy to determining solar irradiance attentuation can assist in determining solar generation for photovoltaics and concentrated solar power towers. Solar generation predictions are important for real time electricity market and pricing studies, real-time dispatch of other generating sources, and energy storage control studies.
ARM dataset includes data from various DOE sites that include sensor information from sun-tracking photometers, radiometers, spectrometer data which is helpful in understanding hyperspectral solar irradiance and cloud dynamics. ARM sites generate large datasets which can be challenging to store, stream, analyze and archive, may be sensitive to sensor noise, and require further measurement verification especially with respect to aerosol composition. Additionally, ARM data coverage is limited to ARM sites motivating future collaboration with partner networks to enhance observational spatial coverage.

U6: Usability > Large Volume
ARM sites generate large datasets which can be challenging to to store, analyze, stream, and archive. Automating ingestion and analysis of data using artificial intelligence can alleviate volume by compressing/reducing data storage and provide novel ways to index and access the data.
R1: Reliability > Quality
Data quality from ARM site sensors can be sensitive to noise and calibration issues requiring field specialists to identify potential problems. Since data volume is large, ingestion of data and identification of measurement drift benefit from automation.
S2: Sufficiency > Coverage
Spatial coverage of radiation and associated ground based atmospheric phenomena are limited to ARM sites within the United States. To increase spatial context collaboration with partner sensor network sites with the DOE and ARM program can expand coverage within the United States. Similar initiatives outside the United States can enable better solar potential studies in regions with different environments.
S3: Sufficiency > Granularity
There is a need for the retrieval of enhanced aerosol composition measurements in addition to ice nucleating particle measurements for better understanding cloud and weather dynamics jointly with solar irradiance for DER site planning and solar potential surveying.

S2: Sufficiency > Coverage
Since testbeds are located on the NIST campus spatial coverage is limited to the institution’s site. Similar datasets outside which combine sensor information from the solar irradiance conditions, and the associated solar generated power at the output of the inverter would require investment in similar site-specific testbeds in different regions.
S4: Sufficiency > Timeliness
The dataset is no longer being maintained after July 2017 which given the investment in equipment for the project may be worth visiting to study the long term changes in the solar efficiency of panels with respect to time and operational degradation.
Data from Solcast is accessible via academic or research institution. Solcast uses course surface elevation models aligned with reanalysis data leading to significant elevation differences between ground data sites and cell height. While a global dataset, coverage is limited to 33 sites with 18 in tropical/subtropical locations and 15 in temperate locations. Time granularity is also between 5-60min.

significant changes in elevation between sites can impact the clear-sky solar irradiance estimation due to variations in the atmosphere that radiation travels through and interacts with. Furthermore, ground stations may be above clouds, which can affect the accuracy of satellite-derived solar irradiance estimates. Solcast uses a coarse surface elevation model aligned with the reanalysis data used, which may lead to significant elevation differences between ground data sites and the cell height.

Current dataset is derived from two previous sky imager datasets in Singapore. Studies that extend beyond Singapore would require similar sensor testbed network, or would require the collation and cultivation of sky image datasets over different temperate environments in addition to the use of proxy data that may not be ground based (remote sensing).
There is a need for annotated labels sky image data for cloud detection and segmentation purposes for improved local and PV site-specific irradiance predictions. The data is ultimately constrained to the coverage area of Singapore and restricts users from its commercial use.

Terrestrial wildlife detection and species classification are essential for understanding the impacts of climate change on terrestrial ecosystems. Similarly to marine wildlife studies, ML can greatly improve these efforts by automatically processing large volumes of data from diverse sources, enhancing the accuracy and efficiency of monitoring and analyzing terrestrial species.
The first and foremost challenge of bioacoustic data is its sheer volume, which makes its data sharing especially difficult due to limited storage options and high costs. Urgent solutions are needed for cheaper and more reliable data hosting and sharing platforms.
Additionally, there’s a significant shortage of large and diverse annotated datasets, much more severe compared to image data like camera trap, drone, and crowd-sourced images.

Data Gap Type
Data Gap Details
S1: Sufficiency > Insufficient Volume
One of the foremost challenges is the scarcity of publicly open and adequately annotated data for model training. It is worth mentioning that the lack of annotated datasets is a common and major challenge applied to almost every modality of biodiversity data and is particularly acute for bioacoustic data, where the availability of sufficiently large and diverse datasets, encompassing a wide array of species, remains limited for model training purposes.
This scarcity of publicly open and well annotated datasets arises from the labor-intensive nature of data annotation and the dearth of expertise necessary to accurately identify species. This is the case even for relatively well-studied taxa such as birds, and is even more notable for taxa such as Orthoptera (grasshoppers and relatives). The incompleteness of our current taxonomy also compounds this issue.
Though some data cannot be shared with the public because of concerns about poaching or other legal restrictions imposed by local governments, there are still considerable sources of well-annotated data that currently reside within the confines of individual researchers’ or organizations’ hard drives. Unlocking these data will partially address the data gap.
To achieve this goal:
A concerted effort to foster a culture of data sharing at both the individual and cross-institutional levels within the ecology community is imperative.
Effective incentives, including financial rewards, funding opportunities, and incentives for publication, must be instituted to incentivize data sharing within the ecology domain. Moreover, due recognition should be accorded to data collectors, facilitated through appropriate data attribution practices and the assignment of digital object identifiers to datasets.
The establishment of standardized pipelines, protocols, and computational infrastructures is essential to streamline efforts aimed at integrating and archiving data from disparate sources.
S2: Sufficiency > Coverage
There exists a significant geographic imbalance in data collected, with insufficient representation from highly biodiverse regions. The data also does not cover a diverse spectrum of species, intertwining with taxonomy insufficiencies.
Addressing these gaps involves several strategies:
Data sharing: Unlocking existing datasets scattered across individual laboratories and organizations can partially alleviate the geographic and taxonomic gaps in data coverage.
Annotation Efforts:
Leveraging crowdsourcing platforms enables collaborative data collection and facilitates volunteer-driven annotation, playing a pivotal role in expanding annotated datasets.
Collaborating with domain experts, including ecologists and machine learning practitioners, is crucial. Incorporating local ecological knowledge, particularly from indigenous communities in target regions, enriches data annotation efforts.
Developing AI-powered methods for automatic cataloging, searching, and data conversion is imperative to streamline data processing and extract relevant information efficiently.
Data Collection:
Prioritize continuous data collection efforts, especially in underrepresented regions and for less documented species and taxonomic groups.
Explore innovative approaches like Automated Multisensor Stations for Monitoring of Species Diversity (AMMODs) to enhance data collection capabilities.
Strategically plan data collection initiatives to target species at risk of extinction, ensuring data capture before irreversible loss occurs.

U6: Usability > Large Volume
One of the biggest challenges in bioacoustic data lies in its sheer volume, stemming from continuous monitoring processes. Researchers face significant hurdles in sharing and hosting this data, as existing online platforms often don’t provide sufficient long-term storage capacity or they are very expensive. Urgent solutions are needed to provide cheaper and more reliable hosting options. Moreover, accessing these extensive datasets demands advanced computing infrastructure and solutions. If there were enough funding sources for this, a lot of people would like to start sharing their bioacoustic data.

The shift from high-inertia generation sources such as thermal plants to low inertia distributed inverter-coupled generation from distributed energy resources introduces new stability and reliability issues. It is imperative to maintain the frequency of the system at a nominal level to prevent damage, instability, and blackouts. Wind generation from turbines can contribute some frequency response and inertia that may benefit the grid by providing a combination of synthetic inertial and primary frequency response to the grid system.

Advanced metering infrastructure data
Details (click to expand)
Advanced Metering Infrastructure (AMI) facilitates communication between utilities and customers through smart meter device systems which collect, store, and analyze per building energy consumption.
AMI data can be retrieved through individual data collection, research partnerships with utilities such as the Irvine Smart Grid Demonstration (ISGD) project conducted by Southern California Edison (SCE) or the smart meter pilot test from the Sacramento Municipal Utility, and through aggregated and anonymized household consumption data such as the Commission for Energy Regulation (CER) hosted by the Irish Social Science Data Archive (ISSDA).
AMI data is challenging to obtain without pilot study partnerships with utilities since data collection on individual building consumer behavior can infringe upon customer privacy especially at the residential level. Granularity of time series data can also vary depending on the level of access to the data whether it be aggregated and anonymized or based on the resolution of readings and system. Additionally, coverage of data will be limited to utility pilot test service areas thereby restricting the scope and scale of demand studies.

There is a significant institutional challenge in processing and analyzing data promptly to inform decision-making. To enhance institutional capacity for leveraging global data sources and analytical methods effectively, a strategic, ecosystem-building approach is essential, rather than solely focusing on individual researcher skill development. This approach should prioritize long-term sustainability over short-term project-based funding.
Funding presents a major bottleneck for ecosystem monitoring initiatives. While most funding allocations are short-term, there is a critical need for sustained and adequate funding to support ongoing monitoring efforts and maintain data processing capabilities.
The first and foremost challenge of bioacoustic data is its sheer volume, which makes its data sharing especially difficult due to limited storage options and high costs. Urgent solutions are needed for cheaper and more reliable data hosting and sharing platforms.

Data Gap Details
S1: Sufficiency > Insufficient Volume
One of the foremost challenges is the scarcity of publicly open and adequately annotated data for model training. It is worth mentioning that the lack of annotated datasets is a common and major challenge applied to almost every modality of biodiversity data and is particularly acute for bioacoustic data, where the availability of sufficiently large and diverse datasets, encompassing a wide array of species, remains limited for model training purposes.
This scarcity of publicly open and well annotated datasets arises from the labor-intensive nature of data annotation and the dearth of expertise necessary to accurately identify species. This is the case even for relatively well-studied taxa such as birds, and is even more notable for taxa such as Orthoptera (grasshoppers and relatives). The incompleteness of our current taxonomy also compounds this issue.
Though some data cannot be shared with the public because of concerns about poaching or other legal restrictions imposed by local governments, there are still considerable sources of well-annotated data that currently reside within the confines of individual researchers’ or organizations’ hard drives. Unlocking these data will partially address the data gap.
To achieve this goal:
A concerted effort to foster a culture of data sharing at both the individual and cross-institutional levels within the ecology community is imperative.
Effective incentives, including financial rewards, funding opportunities, and incentives for publication, must be instituted to incentivize data sharing within the ecology domain. Moreover, due recognition should be accorded to data collectors, facilitated through appropriate data attribution practices and the assignment of digital object identifiers to datasets.
The establishment of standardized pipelines, protocols, and computational infrastructures is essential to streamline efforts aimed at integrating and archiving data from disparate sources.
S2: Sufficiency > Coverage
There exists a significant geographic imbalance in data collected, with insufficient representation from highly biodiverse regions. The data also does not cover a diverse spectrum of species, intertwining with taxonomy insufficiencies.
Addressing these gaps involves several strategies:
Data sharing: Unlocking existing datasets scattered across individual laboratories and organizations can partially alleviate the geographic and taxonomic gaps in data coverage.
Annotation Efforts:
Leveraging crowdsourcing platforms enables collaborative data collection and facilitates volunteer-driven annotation, playing a pivotal role in expanding annotated datasets.
Collaborating with domain experts, including ecologists and machine learning practitioners, is crucial. Incorporating local ecological knowledge, particularly from indigenous communities in target regions, enriches data annotation efforts.
Developing AI-powered methods for automatic cataloging, searching, and data conversion is imperative to streamline data processing and extract relevant information efficiently.
Data Collection:
Prioritize continuous data collection efforts, especially in underrepresented regions and for less documented species and taxonomic groups.
Explore innovative approaches like Automated Multisensor Stations for Monitoring of Species Diversity (AMMODs) to enhance data collection capabilities.
Strategically plan data collection initiatives to target species at risk of extinction, ensuring data capture before irreversible loss occurs.

Camera trap images
Details (click to expand)
Camera traps are likely the most widely used sensors in automated biodiversity monitoring due to their low cost and simple installation. This medium offers close-range monitoring over long-time scales. The image sequences can be used to not only classify species but to identify specifics about the individual, e.g. sex, age, health, behavior, and predator-prey interactions. Camera trap data has been used to estimate species occurrence, richness, distribution, and density.
In general, the raw images from camera traps need to be annotated before they can be used to train ML models. Some of the available annotated camera trap images are shared via Wildlife Insights (www.wildlifeinsights.org) and LILA BC (www.lila.science), while others are listed on GBIF (https://www.gbif.org/dataset/search?q=). However, the majority of camera trap data is likely scattered across individual research labs or organizations and not publicly available. Sharing such images shared could provide significant progress towards fill the gaps associated with the lack of annotated data that currently hinders the progress of efficiently using ML in biodiversity studies. This is what initiatives like Wildlife Insights are looking to do.

M: Misc/Other
There is a significant institutional challenge in processing and analyzing data promptly to inform decision-making. To enhance institutional capacity for leveraging global data sources and analytical methods effectively, a strategic, ecosystem-building approach is essential, rather than solely focusing on individual researcher skill development. This approach should prioritize long-term sustainability over short-term project-based funding.
Funding presents a major bottleneck for ecosystem monitoring initiatives. While most funding allocations are short-term, there is a critical need for sustained and adequate funding to support ongoing monitoring efforts and maintain data processing capabilities.
The scarcity of publicly available and well-annotated data poses a significant challenge for applying ML in biodiversity study. Addressing this requires fostering a culture of data sharing, implementing incentives, and establishing standardized pipelines within the ecology community.

Data Gap Details
S1: Sufficiency > Insufficient Volume
One of the foremost challenges is the scarcity of publicly open and adequately annotated data for model training. It is worth mentioning that the lack of annotated datasets is a common and major challenge applied to almost every modality of biodiversity data and is particularly acute for bioacoustic data, where the availability of sufficiently large and diverse datasets, encompassing a wide array of species, remains limited for model training purposes.
This scarcity of publicly open and well annotated datasets arises from the labor-intensive nature of data annotation and the dearth of expertise necessary to accurately identify species. This is the case even for relatively well-studied taxa such as birds, and is even more notable for taxa such as Orthoptera (grasshoppers and relatives). The incompleteness of our current taxonomy also compounds this issue.
Though some data cannot be shared with the public because of concerns about poaching or other legal restrictions imposed by local governments, there are still considerable sources of well-annotated data that currently reside within the confines of individual researchers’ or organizations’ hard drives. Unlocking these data will partially address the data gap.

S2: Sufficiency > Coverage
There exists a significant geographic imbalance in data collected, with insufficient representation from highly biodiverse regions. The data also does not cover a diverse spectrum of species, intertwining with taxonomy insufficiencies.
Addressing these gaps involves several strategies:
Data sharing: Unlocking existing datasets scattered across individual laboratories and organizations can partially alleviate the geographic and taxonomic gaps in data coverage.
Annotation Efforts:
Leveraging crowdsourcing platforms enables collaborative data collection and facilitates volunteer-driven annotation, playing a pivotal role in expanding annotated datasets.
Collaborating with domain experts, including ecologists and machine learning practitioners, is crucial. Incorporating local ecological knowledge, particularly from indigenous communities in target regions, enriches data annotation efforts.
Developing AI-powered methods for automatic cataloging, searching, and data conversion is imperative to streamline data processing and extract relevant information efficiently.
Data Collection:
Prioritize continuous data collection efforts, especially in underrepresented regions and for less documented species and taxonomic groups.
Explore innovative approaches like Automated Multisensor Stations for Monitoring of Species Diversity (AMMODs) to enhance data collection capabilities.
Strategically plan data collection initiatives to target species at risk of extinction, ensuring data capture before irreversible loss occurs.

Distribution system simulators
Details (click to expand)
Distribution system simulators such as OpenDSS and GridLab-D are crucial for understanding the hosting capacity of distribution level substation feeders because they allow for the analysis of various factors that can affect the stability and reliability of the power grid. These factors include voltage limits, thermal capability, control parameters, and fault current, among others. By simulating different scenarios and conditions, such as the integration of distributed energy resources (DERs) like photovoltaic (PV) solar panels, these tools can provide insights into how the grid can be optimized to accommodate these resources without compromising safety and reliability.
While OpenDSS and GridLab-D are free to use as an alternative when real distribution substation circuit feeder data is unavailable, to perform site-specific or scenario studies, data from different sources may be needed to verify simulation results. Actual hosting capacity may vary from simulation results due to differences in load, environmental conditions, and the level of DER penetration.

EPRI10: Transmission control center alarm and operational data set
Details (click to expand)
Supervisory Control and Data Acquisition (SCADA) systems collect data from sensors throughout the power grid. Alarm operational data, a portion of the data received by SCADA, provides discrete event-based information on the status of protection and monitoring devices in a tabular format which includes semi-structured text descriptions of individual alarm events. Often the data is formatted based on timestamp (in milliseconds), station, signal identification information, location, description, and action. Encoded within the identification information is the alarm message.
Access to EPRI10 grid alarm data is currently limited within EPRI. Data gaps with respect to usability are the result of redundancies in grid alarm codes, requiring significant preprocessing and analysis of code ids, alarm priority, location, and timestamps. Alarm codes can vary based on sensor, asset and line. Resulting actions as a consequence of alarm trigger events need field verifications to assess the presence of fault or non-fault events.

O2: Obtainability > Accessibility
Data access is limited within EPRI due to restrictions with respect to data provided by utilities.
Anonymization and aggregation of data to a benchmark or toy dataset by EPRI to the wider community can be a means of circumventing the security issues at the cost of operational context.
U1: Usability > Structure
Grid alarm codes may be non-unique for different lines and grid assets. In other words, two different codes could represent equivalent information due to differences in naming conventions requiring significant alarm data pre-processing and analysis in identifying unique labels from over 2000 code words. Additional labels expressing alarm priority, for example high alarm type indicative of events such as fire, gas, or lightning, are also encoded into the grid alarm trigger event code.
Creation of a standard structure for operational text data such as those already utilized in operational systems by companies such as General Electric or Siemens can avoid inconsistencies in data.
U3: Usability > Usage Rights
Usage rights are currently constrained to those working within EPRI at this time.
U4: Usability > Documentation
Remote signaling identification information from monitoring sensors and devices encode data with respect to the alarm trigger event in the context of fault priority. Based on the asset, line, or sensor, this identification code can vary depending on naming conventions used. Documentation on remote signal ids associated with a dictionary of finite alarm code types can facilitate pre-processing of alarm data and assessment on the diversity of fault events occurring in real-time systems (as different alarm trigger codes may correspond to redundant events similar in nature).
U5: Usability > Pre-processing
In addition to challenges with respect to the decoding of remote signal identification data, the description fields associated with alarm trigger events are unstructured and vary in the amount of text detail provided. Typically the details cover information with respect to the grid asset and its action. For example, a text description from a line monitoring device may describe the power, temperature, and the action taken in response to the grid alarm trigger event. Often in real world systems the majority of grid alarm trigger events are comprised of short circuit faults and non-fault events, limiting the diversity of fault types found in the data.
To combat these issues, data pre-processing becomes necessary. For remote signal identification data this includes parsing and hashing through text codes, assessing code components for redundancies, and building an associated reduced dictionary of alarm codes. For textual description fields, and post-fault field reports, the use of natural language processing techniques to extract key information can provide more consistency between sensor data. Additionally, techniques like diverse sampling can account for the class imbalance with respect to the associated fault that can trigger the alarm.
U6: Usability > Large Volume
Operational alarm data volume is large given the cadence of measurements made in the system at every millisecond. This can result in high data volume that is tabular in nature, but also unstructured with respect to text details associated with alarm trigger events, sensor measurements, and controller actions. Since the data also contains locations and grid asset information, spatiotemporal analysis can be made with respect to a single sensor and the conditions over which that sensor is operating. Therefore indexing and mining time series data can be an approach for facilitating faster search over alarm data leading up to a fault event. Additionally natural language processing and text mining techniques can also be utilized to facilitate search over alarm text and details.
R1: Reliability > Quality
Alarm trigger events and the corresponding action taken by the events, require post assessment by field workers especially in cases of faults or perceived faults for verification.
U2: Usability > Aggregation
Reports on location, asset, and time can result in false alarm triggers requiring operators to send field workers to investigate, fix, and recalibrate field sensors. The data with respect to field assessments can be incorporated into the data to provide greater context.

Faraday: Synthetic smart meter data
Details (click to expand)
Due to consumer privacy protections, advanced metering infrastructure (AMI) data is unavailable for realistic demand response studies. In an effort to open smart meter data, Octopus Energy’s Centre for Net Zero, has generated a synthetic dataset conditioned on presence of low carbon technologies, energy efficiency, and property type from a model trained on 300 million actual smart meter readings from a United Kingdom (UK) energy supplier.
Faraday synthetic AMI data is a response to the bottlenecks faced in retrieval of building level demand data based on consumer privacy. However, despite the model being trained on actual AMI data, synthetic data generation requires a priori knowledge with respect to building type, efficiency, and presence of low carbon technology. Furthermore, since the dataset is trained on UK building data, AMI time series generated may not be an accurate representation of load demand in regions outside the UK. Finally, since data is synthetically generated studies will require validation and verification using real data or aggregated per substation level data to assess its effectiveness.

Faraday is currently accessible through Centre for Net Zero’s API.
The Variational Autoencoder Model can generate synthetic AMI data based on several conditions. The presence of low carbon technology (LCT) for a given household or property type depends on access to battery storage solutions, solar rooftop panels, and presence of electric vehicles. This type of data may require curation of LCT purchases by type and household. Building type and efficiency at the residential and commercial/industrial level may also be difficult to access requiring the user to set initial assumptions or seek additional datasets. Furthermore, data verification requires a performance metric based in actual readings. This may be done through access to substation level load demand data.
U3: Usability > Usage Rights
Faraday is open for alpha testing by request only.
R1: Reliability > Quality
Verification of AMI synthetic data requires verification which can be done in a bottom up grid modeling manner. For example, load demand at the substation level can be estimated based on the sum of individual building loads which the substation services. This value can then be compared to the actual substation load demand provided through a private partnerships with distribution network operators (DNOs). However, accuracy of a specific demand profile per property or section of properties would require identification of a population of buildings, a connected real-world substation, and residential low carbon technology investment for the set of properties under study.
S2: Sufficiency > Coverage
Faraday is trained from utility provided AMI data from the UK which may not be representative of load demand and corresponding building type and temperate zone of other global regions.

Floating INfrastructure for Ocean observations FINO3
Details (click to expand)
FINO3 is an off-shore wind mast based wind speed and wind direction research platform datasets which include time series data with respect to temperature, air pressure, relative humidity, global radiation, and precipitation. Images from the perspective of the platform provide a snapshot of of environmental conditions directly. The platform is located in the northern part of the German Bight, 80km northwest of the island of Sylt in the midst of wind farms. Wind measurements are taken between 32 to 102 meters above sea level with wind speed measurements taken every 10meters. Data is collected from August 2009 until the present day.
Due to the location, FINO platform sensors are prone to failures of measurement sensors due to adverse outdoor conditions such as high wind and high waves. Often when sensors fail manual recalibration or repair is nontrivial requiring weather conditions to be amenable for human intervention. This can directly affect the data quality which can last for several weeks to a season. Coverage is also constrained to the platform and associated wind farm location.

By accurately measuring forests in 3D, GEDI data play an important role in estimating the forest height as well as canopy height, and thus understanding the amounts of biomass and carbon forests store and how much they lose when disturbed.
GEDI is globally available but has some intricacies, e.g. geolocation errors, and weak return signal if the forest is dense, which bring uncertainties and errors into the estimate of canopy height.
Grid event signature library
Details (click to expand)
Grid2Op is a power systems simulation framework to perform reinforcement learning for electricity network operation, that focuses on the use of topology to control the flows of the grid. Grid2Op allows users to control voltages by manipulating shunts or changing setpoint values of generators, influence active generation by use of redispatching, and manipulate storage units such as batteries or pumped storage to produce or absorb energy from grid when needed. The grid is represented as a graph with nodes being buses and edges corresponding to powerlines and transformers. Grid2Op has several available environments with different network topologies as well as variables that can be monitored as observations. The environment is designed for reinforcement learning agents to act upon with a variety of actions some of which are binary or continuous. This includes changes in topology such as changing bus, changing line status, setting storage, curtailment, redispatching, setting bus values, and setting line status. Multiple reward functions are also available in the platform for experimentation with different agents. It is important to note that Grid2op has no internal modeling of equations of the grids or what kind of solver is necessary to adopt. Data on how the powergrid is evolving is represented by the Chronics. The solver that computes the state of the grid is represented by the “Backend” which utilizes PandaPower to compute power flows.
Grid2Op is a reinforcement learning framework that builds an environment based on topologies, selected grid observations, a selected reward function, and selected actions for an agent to select from. The framework relies on control laws rather than direct system observations which are subject to multiple constraints and changing load demand. Time steps representing 5minutes are unable to capture complex transients and can limit the effectiveness of certain actions within the action space over others. Furthermore, customization of the Grid2Op can be challenging as the platform does not allow for single to multiagent conversion, and is not a suitable environment for cascading failure scenarios due to game over rules.

U4: Usability > Documentation
In the customization of the reward function, there are several TODOs in place concerning the units and attributes of the reward function related to redispatching. Documentation and code comments can sometimes provide conflicting information. Modularity of reward, adversary, action, environment, and backend are nonintuitive requiring pregenerated dictionaries rather than dynamic inputs or conversion from single agent to multiagent functionality.
U5: Usability > Pre-processing
The game over rules and constraints are difficult to adapt when customizing the environment for cascading failure scenarios that may be interesting to conduct for more complex adversaries such as natural disasters. Code base variations between versions especially between the native and Gym formated framework lose features present in the legacy version including topology graphics.
S2: Sufficiency > Coverage
Coverage is limited to the network topologies provided by the grid2op environment which is based on different IEEE bus topologies. While customization of the environment in terms of the “Backend,” “Parameters,” and “Rules” are possible, there may be dependent modules that may still enforce game-over rules. Furthermore, since backend modeling is not the focus of grid2op, verification that customization obeys physical laws or models is necessary.
S3: Sufficiency > Granularity
The time resolution of 5-minute increments may not represent realistic observation time series grid data or chronics. Furthermore, the granularity may limit the effectiveness of specific actions in the provided action space. For example, the use of energy storage devices in the presence of overvoltage has little effect on energy absorption incentivizing the agent to select from grid topology actions such as line changing line status or changing bus rather than setting storage.
R1: Reliability > Quality
The grid2op framework relies on mathematical robust control laws and rewards which train the RL agent based on set observation assumptions rather than actual system dynamics which are susceptible to noise, uncertainty, and disturbances not represented in the simulation environment. It has no internal modeling of the equations of the grids, or what kind of solver that needs to be adopted to solve traditional nonlinear optimal power flow equations. Specifics concerning modeling and preferred solver require users to customize or create a new “Backend.” Additionally, such RL human-in-the-loop systems in practice require trustworthiness and quantification of risk.

For people without expertise in climate data only, it is hard to find the data right for their needs, as there is no centralized platform where they can turn for all available climate data.
Integrating climate data and health data is challenging. Climate data is usually in raster files or gridded format, whereas health data is usually in tabular format. Mapping climate data to the same geospatial entity of health data is also computationally expensive.
For highly biodiverse regions, like tropical rainforests, there is a lack of high-resolution data that captures the spatial heterogeneity of climate, hydrology, soil, and the relationship with biodiversity.

S3: Sufficiency > Granularity
There is a lack of high-resolution data that captures the spatial heterogeneity of climate, hydrology, soil, and so on, which are important for biodiversity patterns. This is because of a lack of observation systems that are dense enough to capture the subtleties in those variables caused by terrain. It would be helpful to establish decentralized monitoring networks to cost-effectively collect and maintain high-quality data over time, which cannot be done by one single country.
LBNL: Solar panel PV system dataset
Details (click to expand)
Lawrence Berkeley National Lab (LBNL) Solar Panel PV System Dataset is a small tabular dataset that includes specific feature data on PV system size, rebate, construction, tracking, mounting, module types, number of inverters and types, capacity, electricity pricing, and battery rated capacity. The LBNL solar panel PV system dataset was created by collecting and cleaning data for 1.6 million individual PV systems, representing 81% of all U.S. distributed PV systems installed through 2018. The analysis of installed prices focused on a subset of roughly 680,000 host-owned systems with available installed price data, of which 127,000 were installed in 2018. The dataset was sourced primarily from state agencies, utilities, and organizations administering PV incentive programs, solar renewable energy credit registration systems, or interconnection processes.
The LBNL solar panel PV system dataset excluded third party owned systems and systems with battery backup. Since data was self-reported, component cost data may be imprecise. The dataset also has a data gap in timeliness as some of the data includes historical data which may not reflect current pricing and costs of PV systems.

The dataset excluded third-party owned systems, systems with battery backup, self-installed systems, and data that was missing installation prices. Data was self reported and may be inconsistent based on the reporting of component costs. Furthermore, some state markets were under represented or missing which can be alleviated by new data collection or use of dataset jointly with simulation studies.

Large-eddy simulations
Details (click to expand)
Very high resolution (finer than 150 m) atmospheric simulations where atmospheric turbulence is explicitly resolved in the model.
Extremely high-resolution simulations, such as large-eddy simulations, are needed. By explicitly resolving processes that are not resolved in current climate models, these simulations may serve as better ground truth for training machine learning models that emulate the physical processes and offer a more accurate basis for understanding and predicting climate phenomena.

S6: Sufficiency > Missing Components
The resolution of current high-resolution simulations is still insufficient for resolving many physical processes, such as turbulence. To address this, extremely high-resolution simulations, like large-eddy simulations (with sub-kilometer or even tens of meter resolution), are needed. By explicitly resolving those turbulent processes, these simulations represent a more realistic realization of the atmosphere and therefore theoretically give better model results. These simulations may serve as ground truth for training machine learning models and offer a more accurate basis for understanding and predicting climate phenomena. Long-term climate simulations at this ultra-high resolution would significantly enhance both hybrid climate modeling and climate emulation, providing deeper insights into global warming scenarios.
Given the high computational cost of running such simulations, creating and sharing benchmark datasets based on these simulations is essential for the research community. This would facilitate model development and validation, promoting more accurate and efficient climate studies.

LiDAR (Light Detection and Ranging) data provides high-resolution, three-dimensional information about surfaces and objects captured using LiDAR technology. Some open datasets that can be used for roof classification include OpenTopography and USGS 3D Elevation Program (3DEP). Many cities, like Boston, London also have their own LiDAR datasets.
Use Case
Data Gap Summary
Micro-synchrophasors (µPMU data)
Details (click to expand)
Micro-phasor measurement units (µPMUs) provide synchronized voltage and current measurements with higher accuracy, precision, and sampling rate making it ideal for distribution network monitoring. For example, µPMUs have an angle accuracy to the allowance of .01 degrees and a total vector error allowance of .05% in contrast to 1 degree and 1% total vector error allowance for classic PMUs. With sampling rates of 10-120 samples per second, µPMUs are capable of capturing dynamic and transient states within the low voltage distribution network allowing for improved event and fault detection and localization. Today most µPMU datasets can be accessed through manual field deployments in test-beds, collaborative research studies, or through publicly available datasets.
For effective fault localization using µPMU data, it is crucial that distribution circuit models supplied by utility partners are accurate, though they often lack detailed phase identification and impedance values, leading to imprecise fault localization and time series contextualization. Noise and errors from transformers can degrade µPMU measurement accuracy. Integrating additional sensor data affects data quality and management due to high sampling rates and substantial data volumes, necessitating automated analysis strategies. Cross-verifying µPMU time series data, especially around fault occurrences, with other data sources is essential due to the continuous nature of µPMU data capture. Additionally, µPMU installations can be costly, limiting deployments to pilot projects over a small network. Furthermore, latencies in the monitoring system due to communication and computational delays challenge real-time data processing and analysis.

Data Gap Type
Data Gap Details
O2: Obtainability > Accessibility
For µPMU data to be utilized for fault localization, the distribution circuit model must be provided by the partnering utility. Typically the distribution circuit lacks notation with respect to the phase identification and impedance values, often providing rough approximations which can ultimately influence the accuracy of localization as well as time series contextualization of a fault. Decreased accuracy of localization can then affect downstream control mechanisms to ensure operational reliability.
U5: Usability > Pre-processing
µPMU data is sensitive to noise especially from geomagnetic storms which can induce electric currents in the atmosphere and impacting measurement accuracy. They can also be compromised by errors introduced by current an potential transformers.
Depending on whether additional data from other sensors or field reports is being used to classify µPMU time series data, creation of a joint sensor dataset can influence quality based on the overall sampling rate and format of the additional non-µPMU data.
U6: Usability > Large Volume
Due to the high sampling rates, data volume from each individual µPMU can be challenging to manage and analyze due to its continuous nature. Coupled with the number of µPMUs required to monitor a portion of the distribution network, the amount of data can easily exceed terabytes. Automation of indexing and mining time series by transient characteristics can facilitate domain specialist verification efforts.
R1: Reliability > Quality
Since µPMU data is continously captured, time series data leading up to or even identifying a fault or potential fault requires verification from other data sources.
Digital Fault Recorders (DFRs) capture high resolution event driven data such as disturbances due to faults, switching and transients. They are able to detect rapid events like lightning strikes and breaker trips while also recording the current and voltage magnitude with respect to time. Additionally, system dynamics over a longer period following a disturbance can also be captured. When used in conjunction with µPMU data, DFR data can assist in verifying significant transients found in the µPMU data which can facilitate improved analysis of both signals leading up to and after an event from the perspective of distribution-side state.
S2: Sufficiency > Coverage
Currently µPMU installation to existing distribution grids have significant financial costs so most deployments have been in the form of pilot projects with utilities. Pilot studies include the Flexgrid testing facility at Lawrence Berkeley National Laboratory (LBNL), Philadelphia Navy Yard microgrid (2016-2017), the micro-synchrophasors for distribution systems plus-up project (2016-2018), resilient electricity grids in the Philippines (2016), the GMLC 1.2.5- sensing and measurement strategy (2016), the bi-national laboratory for the intelligent management of energy sustainability and technology education in Mexico City (2017-2018) based on North American Synchrophasor Initiative (NASPI) reports.
Coverage is also limited by acceptance to this technology due to a pre-existing reliance on SCADA systems which measure grid conditions on a 15 minute cadence. As transients become more common, especially on the low voltage distribution grid, transition to monitoring with higher resolution will become necessary.
S4: Sufficiency > Timeliness
µPMU data can suffer from multiple latencies within the monitoring system of the grid that are unable to keep up with the high sampling rate of the continuous measurements that µPMUs generate. Latencies occur in the context of the system communications surrounding signals as they are being recorded, processed, sent, and received. This can be due to the communication medium used, cable distance, amount of processing, and computational delay. More specifically, the named latencies are measurement, transmission, channel, receiver, and algorithm related.
NASA-USDA global soil moisture data
Details (click to expand)
The NASA-USDA Global soil moisture data offers detailed global soil moisture information at a 0.25°x0.25° resolution, including surface and subsurface moisture, moisture profiles, and anomalies. This dataset integrates satellite observations from SMAP and SMOS with a modified Palmer model using the Ensemble Kalman Filter to enhance soil moisture predictions, especially in areas with sparse precipitation data.
The major change involves managing the size of the data. While cloud platforms offer convenience, they come with costs. Additionally, handling large datasets requires specific techniques, such as distributed computing and occasionally large-memory computing nodes (for certain statistics).

National Institute of Standards and Technology (NIST) campus photovoltaic arrays collected from August 2014-July 2017 measure electrical, temperature, meteorological, spectral curves, UV light, infrared radiation, from PV sensors along with solar inverter power data from multiple testbeds on the National Institute of Standards and Technology campus. The testbeds include a parking lot canopy array, a ground mount array, a roof-tilted array, a rooftop weather station, and a rooftop module test station. Measurements are sampled and saved at high frequency, with one minute averages. The dataset includes metadata with respect to latitude, longitude, and elevation.

S2: Sufficiency > Coverage
Since testbeds are located on the NIST campus spatial coverage is limited to the institution’s site. Similar datasets outside which combine sensor information from the solar irradiance conditions, and the associated solar generated power at the output of the inverter would require investment in similar site-specific testbeds in different regions.
S4: Sufficiency > Timeliness

NOAA's SOLRAD network
Details (click to expand)
The National Oceanic and Atmospheric Administration’s SOLRAD Network monitors the surface radiation of various regions in the united states as part of NOAA’s SURface RADiation budget measurement network. The data includes measurements from different types of instruments and sensors, such as pyrheliometers, pyranometers, radiometers, and UV radiometers. These instruments collect data on incoming radiation, including both visible and UV components, with specific measurement resolutions and accuracy requirements to characterize the Earth’s surface radiation budget. By taking minute interval measurements of incoming solar radiation and accounting for reflection, absorption, and emission, solar energy available for power generation can be accurately forecast for solar farms and large scale solar grid planning projects.
While NOAA’s SOLRAD is an excellent data source for long term solar irradiance and climate studies, data gaps exist for the short term solar forecasting use case (which requires hourly averages). Data quality of hourly averages is lower than that of native resolution data impacting effective short-term forecasting for real-time energy management for grid stability, demand response, real-time market price predictions, and dispatch. Coverage area is also constrained to certain parts of the United States based on the SURFRAD network location.

National Renewable Energy Laboratory (NREL)’s Solar Radiaion Database is a part of the NREL solar radiation resource assessment project which includes hourly and half hour data modeled using NREL’s Physical Solar Model (PSM) with measurements derived from the Geostationary Operational Environmental Satellite (GOES) of National Oceanic and Atmospheric Administration (NOAA), Interactive Multisensor Snow and Ice Mapping System (IMS), and Moderate Resolution Imaging Spectroradiometer (MODIS) and Modern Era Retrospective Analysis for Research and Applications v2 (MERRA-2). PSM derives cloud and aerosol properties and then feeds values as input into a radiative trasfer model (Fast All-sky Radiation Model for Solar applications (FARMS). Dataset can provide users with spectral on demand irradiances based on time, location, and photovoltaic (PV) orientation.
While data coverage is global and based on data derived from satellite imagery as input to the Fast All-sky Radiation Model (FARM), a radiative transfer model, the output is calculated over specific time frames and would require to be calculated and updated for modern times. Furthermore, data is unbalanced as the region that has the longest temporal coverage is the United States. Satellite based estimation of solar resource information may be susceptible to cloud cover, snow, and bright surfaces which would require additional verification from ground based measurements and collation of outside data sources. Additionally, since data is derived from satellites, data may require preprocessing to account for parallax effects when looking at particular regions based on the field of view of the coverage satellite and the region of interest which may not be expressed in the FARM higher level tabular products.

NREL solar power data for integration studies
Details (click to expand)
The NREL Solar Power Data for Integration Studies consist of one year (2006) worth of 5 minute solar power and hourly day ahead forecasts for 6,000 simulated PV plants whose locations were based onthe capacity expansion plan for high penetration renewables in Phase 2 of the western wind and solar integration study and the eastern renewable generation integration study in the United States. NREL generated the data using sub-hour irradiance algorithm and day ahead solar forecast data generated by 3TIER based Numeric Weather Prediction (NWP) simulations for Phase 1 of the Western wind and solar integration study. Data contains utility and distributed-scale PVs which differ in that utility PVs utilize single axis tracking while distributed-scale PVs have fixed tilt. This data is beneficial for reliability studies, dispatch, and electricity market bidding and clearing models.
While the synthetic PV plant data is beneficial to perform forecasting and control simulation case studies when actual data is not present there are limitations with respect verification for site specific projects, representation of coverage areas outside of the US, and modeling assumptions based on data proxies that have to be taken into account when interpreting results.

O2: Obtainability > Accessibility
A lot of ocean data is collected, but a persistent challenge is ensuring that this data is shared and utilized by those who need it. Currently, much of the data remains siloed within individual institutions, making it difficult to access for collaborative purposes. Despite numerous initiatives, such as Ocean Biodiversity Information System (OBIS), Integrated Ocean Observing System (IOOS), and others, data accessibility continues to be the biggest hurdle.
To facilitate large-scale data sharing, there is a need for incentives, robust platforms for data storage, clear guidelines, and straightforward pipelines for data sharing.

U2: Usability > Aggregation
Much of the data is siloed within individual institutions and not easily accessible for collaboration.
U5: Usability > Pre-processing
The volume of raw data (e.g. from imaging and acoustics) is massive, and requires significant effort to annotate and extract insights. In order to accelerate that, some or all of the following solutions can be adopted.
Accelerate the data analysis pipeline, particularly for visual data, through the Ocean Vision AI initiative
Engage the broader community to participate in exploration, discovery, and annotation through initiatives like a mobile game
Target annotation efforts strategically to maximize the impact on model performance, such as focusing on the rare species.
S2: Sufficiency > Coverage
There are massive gaps in the coverage of ocean biodiversity data, with only about 7% of the upper 5 meters of the ocean being regularly monitored, and 30-60% of ocean life still unknown to science. The data is also heavily biased towards coastal regions, with much less coverage of the open ocean.
While collecting data from the deep ocean is technologically challenging, the primary issue is the lack of financial incentives. High seas fall outside national jurisdictions, so data collection often occurs only through mining companies, military operations, or ad hoc research expeditions. The absence of marine protected areas on high seas and the migratory nature of species like phytoplankton further complicate data collection. Financial tools or regulations could incentivize data collection.
Offshore wind meteorological data and LiDAR wind mapping
Details (click to expand)
Off-shore wind and meteorological and Light Detection and Ranging (LiDAR) based wind mapping data can be found from several providers. LiDAR based wind mapping has advantages over traditional wind mast tower measurements namely higher resolution, larger coverage, and improved data quality. This is because LiDAR can measure wind speeds at various heights from the ground reducing the impact of turbulence on measurements that would typically affect mast measurements. Furthermore, LiDAR based wind mapping can provide near real time wind data suitable for control optimization and load forecasting applications. Datasets include:

PowerWorld Simulator and MATPOWER are software tools used for optimizing power systems and include representation of both alternating current (AC) and direct current (DC) systems. PowerWorld Simulator models, analyzes and optimizes power systems for a wide range of configureations and scenarios with the ability to model small distribution networks as well as transmisison systems. MATPOWER is an open source alternative and also solves both the AC and DC version of OPF with DC OPF simplified into a quadratic program using DC modeling assumptions and reducing polynomial costs to second order using real power flows as a function of voltage angles (thereby eliminating voltage magnitude and reactive power). PowerWorld Simulator utilizes a combination of iterative algorithms (Newton-Raphson) with traditional power flow equations.
Traditional OPF simulation software depending on whether it is open source, may require the purchase of licenses for advanced features and functionalities. To simulate more complex systems or regions additional data regarding energy infrastructure, region-specific load demand, and renewable generation may be needed to conduct studies. OPF simulation output would require verification and performance evaluation to assess results in practice. Increasing the granularity of the simulation model by increasing the number of buses, limits, or additional parameters increases the complexity of the OPF problem, thereby increasing the computational time and resources required.

PV Anlage-Reinhart System information for PV systems collated and compiled by SMA with PV inverter data requires creating a user profile requests for specific system access, may lack clear instructions in languages outside of German, and have greater representation of systems located in Germany, Netherlands, and Australia, despite the presence of data globally. Furthermore, a subset of the systems cultivated contain joint energy storage data which may be valuable for DER specific load forecasting studies.

U4: Usability > Documentation
Documentation is primarily in German, and lacks the same detail of data in the English version of the website. Companion works utilizing the data are not readily cited or linked. Since data can only be viewed via the portal, unless express permission is given to download the data, language barriers can be challenging in interpreting the displayed data values.
S2: Sufficiency > Coverage
Coverage is dependent on country of interest with greater representation of PV system data in Europe. In fact, of the 2018 countries represented, the system measurements vary from one system per country to 43,665 systems per country. Systems in Germany, the Netherlands, and Australia have more PV system testbeds than other global regions. Furthermore, depending on the testbed system selected some may have additional information on battery storage though inconsistent throughout most testbeds. This gap can be addressed by increasing the amount of private user contributed system data from diverse regions to supplement those already curated by SMA.
Pecan Street
Details (click to expand)
Pecan Street DataPort began as a Smart Grid Demonstration program through the Pecan Street energy research nonprofit organization which worked closely with the University of Texas at Austin. Funded by the DOE in 2014, the project signed up 1000 research participants from the Mueller community in Austin, Texas to share green button, smart meter, and home energy management system (HEMS) data in 750 homes and 25 commercial properties. Financial incentivization of plug-in electric vehicle use and solar photovoltaic installations with Austin Energy encouraged inhabitants to invest in these Pecan Street to study not only appliance level consumption but electric vehicle charging, rooftop solar, heating, cooling, and eventually water usage. Data has now expanded to cover volunteer households from California, New York and Colorado. Since it’s expansion, Pecan Street has privatized and now data access and products are available for commercial and academic purchase depending on level of access requested.
Pecan Street DataPort requires non-academic and academic users to purchase access via licensing and number of building data features requested. Coverage area of data is primarily concentrated in the Mueller planned housing community in Austin, Texas–a modern built environment which is not representative of older historical buildings that may be in need of energy efficient upgrades and retrofits. In customer segmentation studies and consumer-in-the-loop load consumption modeling, annual sociodemographic survey data may be too coarse and not provide insight into behavioral effects of household members on consumption profiles with time.

S2: Sufficiency > Coverage
The Pecan street dataset represents the same type of modern planned building with similar floor plans and little variations with respect to other buildings. In the initial dataset covering the Mueller community in Austin, Texas, it is important to note that the community began development following 1999 which may not be a representative sample of older buildings which are more likely to require upgrades to energy efficient appliances and systems.
Additionally the dataset primarily covers Texas which is supplied by ERCOT, and has some limited coverage in New York, California, and is growing to include Puerto Reco depending on volunteer participation. This could introduce self-selection bias, as households who participate are already interested in energy saving.
Enrollment of older built environment homes and different temperate regions within the United States and globally, may provide greater insight into household engagement with energy consumption behavior and efficiency monitoring.
S6: Sufficiency > Missing Components
The data does not track real-time occupancy of individuals in the household which may provide insight into behavioral effects on energy consumption. Addition of this data, can also allow for improved customer segmentation models based on consumption, as patterns can change with respect to time and day of the week. The data would also be amenable for consumer-in-the-loop energy management studies with respect to comfort based on customer habitual activity, location in the house, and number of occupants.
S3: Sufficiency > Granularity
For customer segmentation studies by consumption patterns, the dataset contains annual survey responses by participants with respect to household demographics and home features which may be too coarse in granularity for tracking how customer segments change over time.
Power Grid Lib: Optimal power flow benchmark library
Details (click to expand)
The Power Grid Library (PGLib-OPF) is a collection of git repositories that house benchmark data for validating power system simulations. It contains 36 networks with 3-13,659 buses sourced from IEEE Power Flow Test Cases, IEEE Dynamic Test Cases, IEEE Reliability Test System, Polish Test Cases, PEGASE Test Cases, and RTE Test Cases which have been modified to raise optimality gaps to values between 1-10% thereby creating more challenging suboptimal solutions to AC-OPF. By curating and collecting this data, users who want to study more realistic AC-OPF simulation scenarios can directly retrieve compiled bus IDs, branch IDs, generator IDs, power demand, shunt admittance, voltage magnitude range for buses, power injection range for generators, quadratic active power cost function coefficients for generators, branch parameters like series admittance, line charge, transformer parameters, thermal limits, and branch voltage angle difference range which are more realistic. All parameters are conveniently standardized to MATPOWER data file format for direct use.
While network datasets are open source, maintenance of the repository requires continuous curation and collection of more complex benchmark data to enable further AC-OPF simulation and scenario studies. Industry engagement can assist in developing more realistic data though such data without cooperative effort may be hard to find.

Regularly gridded high-resolution atmospheric observations
Details (click to expand)
Though a lot of data is available, a set of regularly gridded 3D high-resolution observations of the atmosphere state (like a higher-resolution version of ERA5) is still needed. This is essential for both an improved understanding of the atmospheric processes and the development of ML-based weather forecast models and climate models.
Physics-based climate models incorporate numerous complex components, such as radiative transfer, subgrid-scale cloud processes, deep convection, and subsurface ocean eddy dynamics. These components are computationally intensive, which limits the spatial resolution achievable in climate simulations. ML models can emulate these physical processes, providing a more efficient alternative to traditional methods. By integrating ML-based emulations into climate models, we can achieve faster simulations and enhanced model performance.

ERA5 is currently widely used in ML-based weather forecast and climate modeling because of its high resolution and ready-for-analysis characteristics. But large volumes of observations, e.g. data from radiosonde, balloons, and weather stations are largely under-utilized. It would be great to create a dataset well-structured like ERA5 but from more observations.
SOLETE, a part of the Energy System Integration Lab (SYSLAB) Technical University of Denmark (DTU) Wind and Energy Systems, includes 15 months measurements with different resolutions (from second to hourly) from the 1st June 2018 to 1st September 2019 covering : timestamp, air temperature, relative humidity, pressure, wind speed, wind direction, global horizontal irradiance, plane of array irradiance, and active power recorded from an 11 kW Gaia wind turbine and a 10 kW PV inverter. This dataset is beneficial for time series forecasting at the inverter level for joint solar and wind DER systems.
While SOLETE is advantageous to use for joint wind solar DER forecasting at the inverter level generation studies, the dataset can be improved by addressing several gaps in data sufficiency, namely expansion of the temporal coverage to include seasonal variations which may be addressed with additional outside data or simulation. Outside data or simulation may also improve scaling of the study to address multiple generation sources (more than one PV array and wind turbine) and the coordination between them to maintain grid reliability and stability. Additionally, a data wish for SOLETE includes the addition of maintenance schedules or system downtime data to more realistically model system dynamics with DERs.

S1: Sufficiency > Insufficient Volume
SOLETE only covers a single wind turbine and PV array which may not take into account considerations when there are multiple generation sources and coordination is required between multiple generation sources of the same type. This gap can be alleviated by physically expanding the network to include multiple PV arrays and wind turbines, or by combining SOLETE with data from additional outside sources from utility, power electronics, and energy tech companies that may have similar datasets to perform larger coordination and grid control studies.
S2: Sufficiency > Coverage
The temporal coverage of SOLETE is limited to 15 months which is unable to capture long-term seasonal variations in joint wind and irradiance data.
S3: Sufficiency > Granularity
The resolution and sampling rate of the joint dataset can impact the precision of the analysis especially when fusing data of different temporal resolutions, from second to hourly together. Aggregation of second level data to hourly data may impact the outcomes of joint short-term solar and wind forecasting.
S6: Sufficiency > Missing Components
SOLETE does not include maintenance schedule data or system downtimes that occurred during data gathering. Retroactively assessing and supplementing the dataset with maintenance schedule data either by simulation or actual data collection from SYSLAB records may improve system forecasting and modeling to include uncertainties with respect to scheduled system maintenance.

Current dataset is derived from two previous sky imager datasets in Singapore. Studies that extend beyond Singapore would require similar sensor testbed network, or would require the collation and cultivation of sky image datasets over different temperate environments in addition to the use of proxy data that may not be ground based (remote sensing).
SWINySEG contains 6768 daytime and night time images of sky/cloud patches along with corresponding binary ground truth maps taken from SWIMSEG and SWINSEG in Singapore using WAHRSIS, a calibrated ground-based whole sky imager over a period of 12 months from January 2016 to December 2016. Ground truth annotations were completed with expertise from the Singapore Meteorological Services.
There is a need for annotated labels sky image data for cloud detection and segmentation purposes for improved local and PV site-specific irradiance predictions. The data is ultimately constrained to the coverage area of Singapore and restricts users from its commercial use.

Satellite Images
Details (click to expand)
Satellite imagery of various spatial and spectral resolutions with global coverage and at different (granular) time slices. There are numerous applications of this type of data in Earth monitoring (glacier, ice extent, snow cover), agriculture (soil composition, crop yield, and crop type detection), forest and high-risk ecosystem monitoring (tree height/type and land cover estimation), flood mapping and management (risk analysis, loss assessment, disaster management during floods), wildfire detection and prediction, cities (building height estimation), energy (wind turbine and solar panel localization), and across sectors (methane, CO2, and N2O measurement).
Different applications require different spatial, spectral, and temporal resolutions and different kinds of labels. For example, for many monitoring applications in the energy, building and transport sectors, spatial resolution is far more important, and very high-resolution RGB images are often used. Spectral resolution is more relevant for instance for vegetation and land use, monitoring land cover (forest, vegetation, etc. ).
Some of the most widely used satellite imagery include Sentinel-1 and 2, MODIS, VIIRS, Landsat which are open to the public and of resolution down to 5m. Commercial satellites can have much higher-resolution images (e.g. 30-cm of Maxar) but they are not open to the public and are not of global coverage. It is worth noting that Planet NICFI provides free high-resolution, analysis-ready mosaics of the world’s tropics for non-commercial use.
Satellite images provide environmental information for habitat monitoring. Combined with other data, e.g. bioacoustic data, they have been used to model and predict species distribution, richness, and interaction with the environment. High-resolution images are needed but most of them are not open to the public for free.

U6: Usability > Large Volume
The sheer volume of data now poses one of the biggest challenges for satellite imagery. When data reaches the terabyte scale, downloading, transferring, and hosting become extremely difficult. Those who create these datasets often lack the storage capacity to share the data. This challenge can potentially be addressed by one or more of the following strategies:
Data compression: Compress the data while retaining lower-dimensional information.
Lightweight models: Build models with fewer features selected through feature extraction. A successful example can be found here.
Large foundation model for remote sensing data: Purposefully construct large models (e.g., foundation models) that can handle vast amounts of data. This requires changes in research architecture, such as preprocessing architecture modifications.
O2: Obtainability > Accessibility
Very high-resolution satellite images (e.g., finer than 10 meters) typically come from commercial satellites and are not publicly available. This is particularly challenging for the Global South. One exception is the NICFI dataset, which offers high-resolution, analysis-ready mosaics of the world’s tropics.
U5: Usability > Pre-processing
Satellite images often contain a lot of redundant information, such as large amounts of data over the ocean that do not always contain useful information. It is usually necessary to filter out some of this data during model training
U2: Usability > Aggregation
Due to differences in orbits, instruments, and sensors, imagery from different satellites can vary in projection, temporal and spatial zones, and cloud blockage, each with its own pros and cons. To overcome data gaps (e.g. cloud blocking) or errors, multiple satellite images are often assimilated. Harmonizing these differences is challenging, and sometimes arbitrary decisions must be made.
U5: Usability > Pre-processing
The lack of annotated data presents another major challenge for satellite imagery. It is suggested that collaboration and coordination at the sector level should be organized to facilitate annotation efforts across multiple sectors and use cases. Additionally, the granularity of annotations needs to be increased. For example, specifying crop types instead of just “crops” and detailing flood damage levels rather than general “damaged” are necessary for more precise analysis.
M: Misc/Other
Cloud cover presents a major technical challenge for satellite imagery, significantly reducing its usability. To obtain information beneath the clouds, pixels from clear-sky images captured by other satellites are often used. However, this method can introduce noise and errors.
M: Misc/Other
There is also a lack of technical capacity in the Global South to effectively utilize satellite imagery.
The resolution of publicly available datasets is insufficient for accurate damage assessments. To improve this, some commercial high-resolution images should be made accessible for research purposes.

Satellite remote sensing data
Details (click to expand)
Remote sensing data with a focus on visible and infrared channels may be utilized to approximate solar irradiance based on cloud cover over a particular region of interest for solar site planning and simulation case studies.
Depending on the region of interest, data can be retrieved from different open data satellites that are both geostationary as well as swath which may differ in spatial and temporal resolutions and coverage area. Additionally, multispectra data may have challenges with respect to preprocessing and preparing the data for analysis. Specifically for medium term solar forecasting, actual ground irradiance may differ from approximations made by models that utilize satellite derived cloud cover products. This is because different cloud types can have different impacts on irradiance. Supplementation with ground based measurements for verification and improvements in granularity are suggested solutions.

Smart inverter operational data is not publicly available and requires partnerships with research labs, utilities, and smart inverter manufacturers. However, the California Energy Commission maintains a database of UL 1741-SB compliant manufacturers and smart inverter models that can then be contacted for research partnerships. In terms of coverage area, while California and Hawaii are now moving towards standardizing smart inverter technology in their power systems, other regions outside of the United States may locate similar manufacturers through partnerships and collaborations.

The accompanied documentation lacks clarity or consistency over time.
U5: Usability > Pre-processing
There is a lack of standardized and coherent structures for data entry in socioeconomic datasets, resulting in users spending significant time on pre-processing tasks such as translating, standardizing, and harmonizing data. Integrating socioeconomic data with other types of data, such as environmental and health data for comprehensive analysis, can be even more challenging due to the differences in data formats and standards.
R1: Reliability > Quality
There is no single unified data source for many socio-economic data, e.g. population, human settlement. Each organization and company comes up with its own dataset and they all differ from each other by a lot. Data validation (e.g. talk to the government and ask for more information) is needed before using the data, but it is hard to do this validation at scalable way because of the time, financial, and technical efforts required.
To improve the reliability and usability of data, data entry methods need to be standardized and automated, and a unified platform for data entry is also wished for.
S2: Sufficiency > Coverage
There is often limited socio-economic data availability in developing regions due to inadequate data collection infrastructure, financial constraints, and political instability.
S3: Sufficiency > Granularity
In developed regions (Global North), there is a lack of granular data for precise analysis. For example, neither the GDP data from the World Bank nor the US CIA is sufficiently detailed for assessing risks from natural hazards. There is a lack of asset-level data for studying the physical risk of infrastructure.
Socioeconomic data, eg. human behaviors are significant predictors of fire. Other than the inherent challenges and gaps of socioeconomic data, aggregating those datasets and harmonizing them with other predictors of fire data in the spatial domain is especially tricky.

Solcast
Details (click to expand)
Solcast is a global solar forecasting and historical solar irradiance data company that compiles and extracts data from Himawari 8, GOES-16, GOES-17, and inputs from Numeric Weather Prediction (NWP) models to update tabular solar data to 10-15minute scale data products. They provide forecasts and sub-hourly estimates that can be used for site-specific direct normal irradiance prediction and solar energy production potentials.
Data from Solcast is accessible via academic or research institution. Solcast uses course surface elevation models aligned with reanalysis data leading to significant elevation differences between ground data sites and cell height. While a global dataset, coverage is limited to 33 sites with 18 in tropical/subtropical locations and 15 in temperate locations. Time granularity is also between 5-60min.

significant changes in elevation between sites can impact the clear-sky solar irradiance estimation due to variations in the atmosphere that radiation travels through and interacts with. Furthermore, ground stations may be above clouds, which can affect the accuracy of satellite-derived solar irradiance estimates. Solcast uses a coarse surface elevation model aligned with the reanalysis data used, which may lead to significant elevation differences between ground data sites and the cell height.
S2: Sufficiency > Coverage
While data products cover global sites, of the sites 33 are covered with 18 representing tropical and subtropical regions and 15 temperate regions. Further work would need to be done to create data products for regions outside the 33 represented as well as for areas with different environmental conditions.

Sub-metered data
Details (click to expand)
Datasets to train and validate non-intrusive load monitoring algorithms require per building aggregate and sub-metered or plug-level consumption profiles. A subset of datasets that can be accessed via a Python API are present .
- Almanac of Minutely Power dataset ![(AMPds2)] (https://dataverse.harvard.edu/dataset.xhtml?persistentId=doi:10.7910/DVN/FIE0S4): A single building electricity, water, and natural gas consumption dataset from a home in Burnaby, British Columbia, Canada from 2012-2014 which includes environment and utility billing data as well.
- Commercial building energy dataset : A dataset of 6 commercial buildings on the Indraprastha Institute of Information Technology (IIIT-Delhi) from August 2013 to the present containing data with respect to the total power consumption, sub-metered data with respect to elevators, air handling units (AHUs), uninterruptible power supplies (UPS), and central campus heating, ventilation, and air conditioning (HVAC) pumps and chillers at a 30 second cadence.
- : A dataset comprised of aggregate and disaggregated power consumption from 15 southern German homes monitored at 1Hz containing 50 appliances including dishwashers, washing machines, refrigerators and dryers over a span of 3.5 years (2016-2020). Aggregated data includes three-phase measurements. This dataset also contains event start and stop timestamps for 14 appliances.
- Dutch Residential Energy Dataset : Requires request. Consists of data collected from a single household in the Netherlands which contains the appliance level and total energy consumption over two months. Appliance consumption measured was a refrigerator, washing machine, central heating, microwve, oven, cooker, blender, toaster, television, fan, living room outlets, and a laptop recorded with a sampling frequency of 1 Hz. DRED additionally has data on human occupancy based on WiFi and bluetooth signals received from occupant smartphones and wearable devices to allow for locating the consumer without setting up the home with more intrusive monitoring devices.
- Electricity Consumption and Occupation : A dataset collected from June 2012-January 2013 covering 6 home in Switzerland where 6-10 smart plugs were deployed in each household. Aggregate consumption at the building level was measured in three phases to capture voltage, current, and phase shifts. Occupancy data was tracked by residents manually and via a passive infrared entry door sensor.
- : A dataset of 9 households in Austria and Italy for one year covering December 2013-April 2014. Data included aggregated and submetered appliance level data which varied depending on the appliance inventory of the household covering active power measurements taken at a frequency of 1Hz.
- : A dataset from October 2017-December 2017 recording smart meter measurements from 10 machines and the main terminal of an electronics production site operated by the Institute of Data Processing and Electronics (IPE) at Karlsruhe Institute of Technology (KIT) in Germany at a cadence of 5 seconds with measurements with respect to active power, reactive power, voltage, frequency, and distortion.
- Indian data for Ambient Water and Electricity Sensing : Total consumption, appliance level, as well as circuit panel level in a single family home in New Delhi, India was collected in summer of 2013 over the course of 73 days. Additional quantities such as water usage from an overhead tank, and network strength based on packet loss was also jointly measured.
- : A joint electricity, gas, temperature, humidity, and light dataset for 255 homes in the UK from August 2016 to June 2018. Aggregate and sub-metered consumption was measured at 1 second intervals, while temperature, humidity and light were measured at 12 second intervals. Household occupancy was measured through initial surveys with respect to socio-demographic data and self-reported updates to the data in the event that there was a change in occupancy.
- Reference Energy Disaggregation Dataset (REDD): Contains 119 days worth of aggregate consumption taken in 2011 from 10 residential buildings located in the greater Boston area. The data includes meter level phases of power, and voltage recorded at 15kHz as well as sub-meter level 24 circuits labeled by appliance category and measured at a cadence of 0.5Hz and 1Hz for large and small plug level appliances respectively.
- : A dataset containing aggregate and individual appliance monitor sub-meter data taken every 8 seconds from 20 UK households from September 2013 to September 2015. Of the 8 households, 6 households had rooftop solar panels however, 3 were rewired to remove the effect of generation.
- : This dataset is comprised of metered and sub-metered data from three homes in west Massachussetts taken over a period of three years. Measurements included average household load, circuit-level load, and plug load per second. Accompanying generation data from solar panels and wind turbines is available for one of the three homes. Environmental data with respect to the outdoor weather and indoor temperature and humidity are provided as well as occupancy information through wall switch data, doors, and motion sensors. HVAC trigger events and corresponding temperature settings and operational status are also provided.
- UK Domestic Appliance-Level Electricity data set : A dataset comprised of measurements of aggregated as well as individual appliance level consumption recorded every 6 seconds from 5 UK homes taken from researchers at Imperial College. The continuous coverage varied per house ranging from 39 to 786 days spanning dates from 2012 to 2015. Data included whole house active power, apparent power, and RMS voltage. Appliance level measurements were taken every 6 seconds using individual appliance monitors for up to 54 appliances per residence.
For accurate NILM studies, benchmark datasets are required that include not only consumption but generation as well. While some datasets may include some generation information, most studies do not take rooftop solar generation into account. Additionally, loads such as electric vehicles or battery storage were not present. Building level data focused mostly on single family housing units in specific areas limiting the diversity of representation. Furthermore, most datasets are no longer maintained following study close.

For the Non-intrusive Load Monitoring Toolkit which provides researchers a toolkit for evaluating different algorithms on datasets introduced, developers had to collate and fuse data from a variety of formats that were specific to each study. Using the REDD dataset format as inspiration, the toolkit developers created a standard energy disaggregation data format(NILMTK-DF) with common metadata and structure which required manual dataset specific preprocessing.

Using the REDD dataset format as inspiration, the toolkit developers created a standard energy disaggregation data format(NILMTK-DF) with common metadata and structure which required manual dataset specific preprocessing.
Sub-metered data relies on the sensor network installation made in the building. Depending on the technology used, some sensors required calibration or were prone to malfunctions and delays. Additionally, interference from other devices could also be present in the aggregate building level readings, such as that experienced by REFIT, that needed to be addressed manually to enhance the usability of the dataset.
R1: Reliability > Quality
In the AMPds2 data the sum of the sub-metered consumption data did not add up to the whole house consumption due to some rounding error in the meter measurements.
Datasets that required self-reporting may introduce participant bias as the resolution with which households update occupancy information may vary. Additionally, consumption behaviors in volunteer households may have a pre-existing propensity for energy efficient actions based on enthusiasm for study participation and therefore not representative of the general population. For example, in UK-DALE, participants were comprised of masters and PhD graduate students from Imperial College which may have energy usage patterns and behaviors that are not representative of the general population.
S2: Sufficiency > Coverage
In AMPds2 data there were some missing data from electricity and water and natural gas readings. Additionally, there existed un-metered household loads which were not accounted for in the whole house reading and dishwasher consumption did not have a direct water meter for monitoring. REFIT also did not monitor appliances that could not be connected to individual appliance monitors such as electric ovens. Depending on the built environment, even with the use of external plugload sensors for disaggregated load consumption, some larger loads may not be able to be connected to building level meters. For example, in the GREEND dataset, electric boilers in Austria were connected to separate meters. In the UMass smart home dataset, gas furnaces, exahust fans, and recirculator pump loads were not able to be monitored.
AMPds2, DEDDIAG, DRED, iAWE, REDD, REFIT, and UMass smart home dataset all gather data in single family homes which may not be representative of the diversity of buildings in terms of age, location, construction, and potential household demographics. REFIT data covers different single family home types such as detached, semi-detached, and mid-terrace homes that ranged from 2-6 bedrooms with builds from the 1850s to 2005. GREEND covers apartments in addition to single family homes but the number of households was 9. AMPds2, DRED, iAWE only cover a single household. Additionally, datasets are specific to the location where the measurements were taken which are susceptible to the environmental conditions of the region as well as the culture of the population. For example, REDD consists of data from 10 monitored homes which may not be representative of common appliances contributing to the overall load of the broader population outside of Boston.
COMBED contains complex load types that may rely on variable-speed drives as well as multi-state devices, which the other datasets do not contain which may be due to the difference in building type but could also be due to the lack of diversity of appliance representation.
ECO data relied on smart plugs for disaggregated load consumption measurements which varied between households depending on the smart plug appliance coverage. For all households the total consumption was not equal to the sum of the consumption measured from the plugs alone, indicative of a high proportion of non-attributed consumption.
S6: Sufficiency > Missing Components
All datasets mentioned do not include electric vehicle loads. REDD, AMPds2, COMBED, DEDDIAG, DRED, GREEND, iAWE, UK-DALE do not include generation from rooftop solar. REFIT contains solar from three homes but they were not the focus of the study and were treated as solar interference to the aggregate load. The UMass smart home dataset only had representation of one home with solar and wind generation, though at a significantly larger square footage and build compared to the other two homes that were featured.
While DRED provided occupancy information through data collected from wearable devices with respect to the home and ECO and IDEAL through self-reporting and an infrared entryway sensor, all other studies did not.
The majority of datasets are not amenable to human in the loop user behavior analysis with respect to consumption patterns, response to feedback, and the effectiveness in load shifting to promote energy conserving behaviors due to their lack of representation.
While AMPds2 includes some utility data, most datasets do not incorporate billing or real time pricing. This type of data would be beneficial as it varies from time, season, region, and utility.
Battery storage was not taken into account in all building consumption datasets.

Public datasets from government agencies such as the EIA, EPA, FERC, and PHMSA are not ready for use in analysis ready data products. Data is often tabular as zip files with different file formats that may not share common identifiers or schema to readily join data. Collating, collecting, and merging these datasets can often provide greater context to the state of the energy system and the effectiveness of policy measures. Data can also be missing based on reporting gaps and redacted per-plant pricing information. While PUDL seeks to overcome the gaps by merging datasets based on entity matching and interpolation challenges still remain in terms of maintenance as usability can be sensitive to original source data format changes, updates, and new initiatives. The datagaps experienced in the maintenance of this dataset will be highlighted with respect to the source data that PUDL mines.

Data Gap Type
Data Gap Details
U1: Usability > Structure
The structure of PUDL is maintained, however, the structure of the source material from FERC, EIA, EPA, and other data providers can vary significantly between reporting years, new initiatives, and individual reporting details. For example, individual power plant identification numbers and associated operational data across sources may differ despite referencing the same plant.
Additionally, data versioning in spreadsheet format files, is non-existent, making it difficult to track updates and content changes made to an individual file that is provided by the regulatory agencies between website updates.
Common standards and formatting across agency datasets and reporting with documentation can provide the open source community with improved direction and responsiveness to changes between years and forms.
U2: Usability > Aggregation
Aggregation of data between publicly available agency provided materials is challenging as schema and naming conventions for similar information in addition to resolution can vary between sources. Probabilistic named entity recognition and interpolation techniques are utilized to join datasets where feasible. However, when aggregating public data with private data obtained by paid purchase access, data may not only require use of private APIs but may also have a significantly different schema or format. Utilizing relational database formatting standards and best practices as a universal standard across data providers can make joining data along common aliases, ids and correlations easier.
U3: Usability > Usage Rights
PUDL uses the Creative Commons Attribution License v4.0.
While PUDL sources data from public government regulatory agencies, data provided by private utility system operators may have quasi-public licensing restrictions. Despite the utility data being be provided to regulatory agencies, use by the wider public could be legally disputed. To overcome this, usage rights may be explicitly stated by the provider and/or the government agency publishing the data.
U4: Usability > Documentation
PUDL maintains and updates documentation as more datasets are incorporated to its database. However, Catalyst Cooperative, the group responsible for the continuous development of the project, monitor source datasets for changes in format and requirements between years.
U5: Usability > Pre-processing
PUDL seeks to create a parsing pipeline that allows concatenation and collation of information with respect to data requested by regulatory agencies. However, this parsing pipeline can face challenges as schema and format undergo changes with time. For example, FERC data has changed database formats from pdf to XBRL. Additionally, data sources can be semi-structured in nature requiring significant pre-processing and expertise in a variety of data formats including those that may be custom to the reporting agency.
Energy data in the form of PDFs can bottleneck data pipelines utilizing optical character recognition (OCR) technology due to scan quality thereby affecting data extraction especially data does not have a unified reporting format.
While PUDL relies on natural language processing techniques such as probabilistic entity matching to mitigate the challenges faced, oftentimes, these data gaps require human verification and extensive manual pre-processing . This can introduce technical debt while working with a solution provider to understand and better digest data contents.
S2: Sufficiency > Coverage
PUDL coverage is isolated to regulatory agencies and third party organizations within the United States.
S3: Sufficiency > Granularity
Granularity of data is constrained on a annual, monthly or quarterly basis depending on the source of data compiled by PUDL. PUDL utilizes interpolation techniques to unify resolution, however, this requires continuous maintenance and examination of historical data.
S6: Sufficiency > Missing Components
PUDL would like to incorporate open weather model data into the database to facilitate research into load demand and renewable generation. This would require down-sampling of weather model outputs in order to match pre-existing database resolution. Additionally, data with respect to transmission and congestion from grid operators would provide greater system context to the data provided by public agencies.
UAV LiDAR image data over power lines

LiDAR remote sensing data from unmanned aerial vehicles for power line inspection of right of way data on transmission and distribution lines can be accessed from private providers such as LUMA Energy and COR3. China Southern Power Grid has UAV transmission line data from the Yunnan RoW-1, Yunnan RoW-2, and Hubei RoW 4. Open source EPRI distribution inspection imagery is available and labeled with information regarding polyline class (conductor, other wire) and polygon classes (pole, crossarm, insulator, cutouts, transformer, and background structure). These datasets can provide opportunities of analyzing images paired with geolocated GIS data to identify vegetation management areas near lines.
Unmanned aerial vehicle (UAV) or drone imagery for vegetation management near transmission and distribution lines may require partnerships with private companies and utilities for access and usage. LiDAR data is sparse and may partially scan power transmission lines resulting in poor data quality. Coverage area is often relegated to right of way (RoWs) of interest which may require continuous monitoring for future vegetation growth and inspection.

Data Gap Type
Data Gap Details
R1: Reliability > Quality
ERA5 is often used as “ground truth” in bias-correction tasks, but it has its own biases and uncertainties. ERA5 is derived from observations combined with physics-based models to estimate conditions in areas with sparse observational data. Consequently, biases in ERA5 can stem from the limitations of these physics-based models. It is worth noting that precipitation and cloud-related fields in ERA5 are less accurate compared to other fields and are not suitable for validating ML models. A higher-fidelity atmospheric dataset, such as an enhanced version of ERA5, is greatly needed. Machine learning can play a significant role in this area by improving the assimilation of atmospheric observation data from various sources.

Environmental DNA (eDNA) refers to genetic material obtained from environmental samples like soil and water after being shed by living or dead organisms. By analyzing this genetic material, researchers can detect and monitor species present in a non-invasive and efficient manner, aiding biodiversity studies, conservation efforts, and environmental monitoring. Some eDNA data can be found in GBIF. It is worth mentioning that BIOSCAN-5M is a comprehensive dataset containing multi-modal information, including DNA barcode sequences and taxonomic labels for over 5 million insect specimens, presenting as a large reference library on species- and genus-level classification tasks.

It is worth mentioning that BIOSCAN-5M is a comprehensive dataset containing multi-modal information, including DNA barcode sequenceses and taxonomic labels for over 5 million insect specimens, presenting as a large reference library on species- and genus-level classification tasks.

More data is needed to develop a more accurate and robust ML model. It is also important to note that SUBX data contains biases and uncertainties, which can be inherited by ML models trained with this data.

Data Gap Type
Data Gap Details
S1: Sufficiency > Insufficient Volume
Larger models generally offer improved performance for developing data-driven sub-seasonal forecast models. However, with only a limited number of models contributing to the SUBX dataset, there is a scarcity of training data. To enhance ML model performance, more SUBX data generated by physics-based numerical weather forecast models is required.
