POWER Monthly Radiation

This monthly radiation service provides time-enabled global Analysis Ready Data (ARD) parameters from 1984 to 2023 for the NASA Prediction Of Worldwide Energy Resource (POWER) Project's communities.

The Prediction Of Worldwide Energy Resource (POWER) Project gathers NASA Earth Observation data and parameters related to the fields of surface solar irradiance and meteorology to serve the public in several free, easy-to-access, and easy-to-use methods. POWER helps communities become resilient amid observed climate variability by improving data accessibility, aiding research in renewable energy development, building energy efficiency, and agriculture sustainability. POWER is funded through the NASA Earth Action Program within the Earth Science Mission Directorate at NASA Langley Research Center (LaRC).
