The CAMS radiation service values radiation values are compared to the BSRN measurements of 14 stations located in the Meteosat Second Generation satellite coverage following the protocol of validation described here on SoDa. The 1 min BSRN station measurements have been qualified using the quality check procedure available here. The validation results are available for the 15 min, hourly, daily and monthly time step, and for the Global Horizontal and the Direct Normal components.
