Remote Sensing of Solar Surface Radiation

We have processed a global irradiance and direct irradiance climate data record from the Meteosat first generation satellites (Meteosats 2 to 7, 1983–2005). The CDRs are available free of charge for all purposes from the EUMETSAT‘s Satellite Application Facility on Climate Monitoring Web User Interface at monthly, daily and hourly means at a spatial resolution of 0.03 degrees.

The processing employed a climate version of the well known Heliosat algorithm combined with a open source clear sky model (gnu-MAGIC) using an eigenvector look-up table method. Modifications to the Heliosat method include a self-calibration algorithm as well as a running mean based clear sky retrieval algorithm.

More information to this dataset and related algorithms can be found on our CM SAF project web site at MeteoSwiss.
