Surface Radiation Data Set - Heliosat (SARAH) - Edition 3

The third edition of the Surface Solar Radiation Data Set - Heliosat (SARAH-3) is a satellite-based climate data record of the solar surface irradiance (SIS), the surface direct irradiance ((direct horizontal and direct normalized, SID and DNI), the sunshine duration (SDU), the photosynthetically active radiation (PAR), daylight (DAL), and the effective cloud albedo derived (CAL) from satellite-observations of the visible channels of the MVIRI and the SEVIRI instruments onboard the geostationary Meteosat satellites. SARAH-3 covers the time period 1 Jan 1983 - 31 Dec 2020 as climate data record (CDR) and is operationally extended as Interim Climate Data Record (ICDR) to the present with a latency of 5 days; the data cover the region ±65° longitude and ±65° latitude. The products are available as monthly (P1M) and daily (P1D) means, and as 30-min instantaneous data (PT30M) (sunshine duration is available as monthly and daily sum) on a regular latitude/longitude grid with a spatial resolution of 0.05° x 0.05° degrees. The data record is complemented with a comprehensive documentation of the algorithms used and the generation of the data record. Validation report and user guidance are also available. All product are available via the CM SAF Web User Interface. The daily and monthly mean surface incoming shortwave radiation (SIS) and the daily and monthly sums of sunshine duration (SDU) are also provided via EUMETCast. Note: the CDR coverage ends on the 31/12/2020. Dates after 31/12/2020 are covered by the ICDR.
