Surface meteorology and Solar Energy (SSE)
Data and Information

A new POWER home page with enhanced responsive web data services and mapping capabilities will soon replace the current POWER home page. The new POWER will include improved solar and meteorological data with all parameters available on a 0.5-degree global grid. A beta version of the new home page, featuring the updated parameters, schedule updates and FAQ, can be accessed at POWER. Please direct any questions to POWER Project Team.

The Release 6.0 Surface meteorology and Solar Energy (SSE) data set contains parameters formulated for assessing and designing renewable energy systems. This latest release contains new parameters based on recommendations by the renewable energy industry and it is more accurate than previous releases. Global, regional and site specific radiation and meteorological data allow quick evaluation of potential renewable energy projects for any region of the world. The SSE data set is formulated from NASA satellite- and reanalysis-derived insolation and meteorological data for the 22-year period July 1983 through June 2005. Results are provided for 1° latitude by 1° longitude grid cells over the globe.
