Solar Irradiation Data Sources
This page is being created by Alex Hirzel and his research group at Michigan Tech to catalog publicly-available sources of solar irradiance data.
Goals for this page
Measured solar irradiation data is used in forecasting research. This page aims to provide a list of data sources and a summary of each. For now, we are focused on high-resolution (one hour or finer) data.
|NSRDB||USA||maps of sites: 1961-1990, 1991-2010||1 hour||Downloadable `.csv`||?||"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."
