National Solar Radiation Data Base

Data Sets
National Solar Radiation Database 1961-1990 The National Solar Radiation Data Base 1961-1990 (NSRDB) contains 30 years of solar radiation and supplementary meteorological data from 237 NWS sites in the U.S., plus sites in Guam and Puerto Rico.		National Solar Radiation Database 1991-2010 Update The updated 1991-2010 National Solar Radiation Database holds solar and meteorological data for 1,454 locations in the United States and its territories.		National Solar Radiation Database 1998-2014 Update The current version of the NSRDB (v2.0.0) was developed using the Physical Solar Model (PSM), and offers users the latest available data (1998–2014). NSRDB comprises 30-minute solar and meteorological data for approximately 2 million 0.038-degree latitude by 0.038-degree longitude surface pixels (nominally 4 km2). The area covered is bordered by longitudes 25° W on the east and 175° W on the west, and by latitudes -20° S on the south and 60° N on the north.
