POWER Project Information

by ASDC - ingridgs » Thu Aug 18, 2022 12:11 pm America/New_York


The NASA Prediction Of Worldwide Energy Resources (POWER) Project, a NASA Applied Sciences program, improves the accessibility and usage of NASA Earth Observations (EO) supporting community research in three focus areas: 1) renewable energy development, 2) building energy efficiency, and 3) agroclimatology applications. POWER can help communities be resilient amid observed climate variability through the easy access of solar and meteorological data via a variety of access methods.

The latest POWER version includes hourly-based source Analysis Ready Data (ARD), in addition to enhanced daily, monthly, annual, and climatology ARD. The daily time-series spans 40 years for meteorology available from 1981 and solar-based parameters start in 1984. The hourly source data are from Clouds and the Earth's Radiant Energy System (CERES) and Global Modeling and Assimilation Office (GMAO), spanning 20 years from 2001. The hourly data will provide users the ARD needed to model the energy performance of building systems, providing information directly amenable to decision support tools introducing the industry standard EPW (EnergyPlus Weather file).

POWER also provides parameters at daily, monthly, annual, and user-defined time periods, spanning from 1984 through to within a week of real-time. Additionally, POWER provides are user-defined analytic capabilities, including custom climatologies and climatological-based reports for parameter anomalies, ASHRAE® compatible climate design condition statistics, and building climate zones.

The ARD and climate analytics will be readily accessible through POWER's integrated services suite, including the Data Access Viewer (DAV). The DAV has recently been improved to incorporate updated parameter groupings, new analytical capabilities, and new data formats. POWER also provides a complete API (Application Programming Interface) that allows users to obtain all the parameters in the DAV plus additional parameters for larger repetitive orders or from within the user's own analytic tools. Additionally, POWER’s entire data product catalog is available through Amazon Web Services (AWS) Open Data Registry (ODR) via a free and publicly accessible Simple Storage Service (S3). 

Update Frequency
Near Real Time (NRT); as soon as source data becomes available from our source data providers.
  • Meteorological: ~2-3 days
  • Solar ~5-7 days
For more information see the NASA POWER Availability Dashboards.

Tools & Applications
  • Data Access Viewer (DAV): Responsive web mapping application providing data subsetting, charting, and visualization tools in an easy-to-use interface.
  • API Services Catalog: Access the POWER data holdings through your own custom scripts and scalable applications. 
  • ArcGIS Image Services: GIS-ready, time-enabled ArcGIS Image Services for mapping, visualization, and spatial analysis.
