About the POWER Project

NASA's goal in Earth science is to observe, understand, and model the Earth system to discover how it is changing, to better predict change, and to understand the consequences for life on Earth. The Applied Sciences Program, within the Science Mission Directorate (which replaced both the Office of Earth Science and the Office of Space Science), serves NASA and Society by expanding and accelerating the realization of societal and economic benefits from Earth science, information, and technology research and development.

The Prediction Of Worldwide Energy Resources (POWER) project was initiated to improve upon the current renewable energy data set and to create new data sets from new satellite systems. The POWER project targets three user communities: (1) Renewable Energy, (2) Sustainable Buildings, and (3) Agroclimatology.

Renewable Energy

Renewable Energy

The Renewable Energy Archive is designed to provide access to parameters specifically tailored to assist in the design of solar and wind powered renewable energy systems.

Sustainable Buildings

Sustainable Buildings

The Sustainable Buildings Archive is designed to provide industry-friendly parameters for the buildings community, to include parameters in multi-year monthly averages.



The Agroclimatology Archive is designed to provide web-based access to industry-friendly parameters formatted for input to crop models contained within agricultural DSS.

About Us

The Prediction of Worldwide Energy Resources (POWER) project was initiated to improve upon the current SSE data set and to create new data sets from new satellite systems and forecast modeling data.


Use of POWER Data: When POWER data products are used in a publication, we request the following acknowledgment be included:
"These data were obtained from the NASA Langley Research Center (LaRC) POWER Project funded through the NASA Earth Science/Applied Science Program."

Reprints Please: The POWER Project kindly requests a reference, web link and/or a reprint of any published papers or reports or a brief description of other uses (e.g., posters, oral presentations, etc.) of data products that we have distributed. This will help us determine the use of data that we distribute, which is helpful in optimizing product development. It also helps us to assess our value to the community. Please contact us at POWER Project Team for additional information on sending reference material.

Redistribution of Data: To assist the POWER Project in providing the best service to the scientific community, we request notification if you transmit POWER data to other researchers.

Acknowledgement: The Prediction of Worldwide Energy Resources (POWER) Project is funded through the NASA Applied Sciences Program within the Earth Science Division of the Science Mission Directorate. The POWER team could not have completed this task without both technical and scientific inputs from the following Earth Science Division teams: The World Climate Research Programme (WCRP) Global Energy and Water Cycle Experiment's (GEWEX) Surface Radiation Budget (NASA/GEWEX SRB) and the Clouds and the Earth's Radiant Energy System (CERES) projects at NASA LaRC and the Global Modeling and Assimilation Office at the NASA Goddard Space Flight Center. The data obtained through the POWER (Prediction of Worldwide Energy Resources) web services was made possible with collaboration from the the NASA LaRC Sciences Data Center (ASDC).

Section 508 Rehabilitation Act Information: The Science Directorate at NASA Langley Research Center is dedicated to compliance with accessibility standards developed under Section 508 of the Rehabilitation Act. However, technical and financial limitations occasionally prevent some information or data from being presented in a manner that is readily accessible to persons with certain disabilities. If you have any difficulty viewing a Section 508 Rehabilitation Act Information web page with adaptive technology, please contact the NASA Official or Curator responsible for the web page. Either an alternative format of the web page or manual assistance obtaining the required information will be provided.
