NSRDB Hourly Data Files
The Hourly Data Files are derived from the National Solar Radiation
Data Base hourly data in
synoptic format. They contain global horizontal solar irradiance, direct
normal solar irradiance, and
diffuse horizontal solar irradiance for each hour from January 1, 1961 through
December 31, 1990 (if available) for each of the 239 sites in the NSRDB. See the
National Solar Radiation Data Base User's Manual
for a complete description of the NSRDB.
