"The Surface Solar Radiation Data Set - Heliosat (SARAH) is a satellite-based climatology of the solar surface irradiance (SIS), the surface direct normalized irradiance (DNI) and the effective cloud albedo (CAL) derived from satellite observations of the visible channels of the MVIRI and SEVIRI instruments onboard the geostationary Meteosat satellites. The data are available from 1983 to 2013 and cover the region ±65° longitude and ±65° latitude. The products are available as monthly, daily, and hourly averages on a regular latitude/longitude grid with a spatial resolution of 0.05° x 0.05°. The data set is complemented with a comprehensive documentation of the applied algorithms as well as validation studies and user guidance."
