Irradiation Validation Report

This service performs a comparison of the daily global horizontal irradiation (GHI) of HelioClim-3 version 4, HelioClim-3 version 5 or CAMS Radiation Service estimates of surface solar irradiation against 31 qualified ground measurements obtained from the World Radiation Data Center (WRDC), an agency of the World Meteorological Organization. It returns a HTML page that contains statistics of comparison and graphs. The time coverage of the CAMS Radiation Service and HelioClim-3 version 5 databases is from 2004-02-01 up to 2 days ago, and up to d-1 for the version 4. Each station has its own temporal coverage. The period of validation must be selected within this period of data availability. The geographical coverage is the field-of-view of the Meteosat satellites, roughly speaking Europe, Africa, Atlantic Ocean, Middle East (-66° to 66° in both latitudes and longitudes).
 
This service is making use of data from the Copernicus Atmosphere Monitoring Service (CAMS), a European Union programme implemented by ECMWF.
