CAMS services are composed of two services: CAMS radiation service and CAMS McClear.    >> Brief description of these services


The method Heliosat-4 processes Meteosat images to create the CAMS radiation service. Consequently, CAMS radiation service covers Europe, Africa, the Mediterranean Basin, the Atlantic Ocean and part of the Indian Ocean (-66° to +66° both in latitude and longitude).


CAMS radiation service delivers spectrally-integrated 15 minute Global Horizontal Irradiance (GHI) and Direct Normal Irradiance (DNI) values.


Heliosat-4 contributes to a detailed assessment of optical variables in the atmosphere (gaz, aerosols, water vapour), clouds and ground albedo. One of the major results is the clear-sky model McClear that estimates the radiation that should be received if the sky were clear anywhere, since 2004, available worldwide. This model has been created by the Centre O.I.E., the  DLR, the Finnish Meteorological Institute), and the  European Center for Medium-range Weather Forecasts ECMWF.
