CM SAF has discontinued the processing of the SEVIRI-based Environmental Data Record (EDR) of Fractional Cloud Cover (CFC) and Surface Incoming Shortwave Radiation (SIS), with the switch from Meteosat-10 to Meteosat-11 in early March 2018.
Thursday, 24 May 2018
They are replaced by so-called Interim Climate Data Records (ICDRs), which are a continuation of the respective Thematic Climate Data Records (TCDRs), helping to support climate monitoring applications.
The ICDRs of CFC and SIS monthly mean products, currently pre-operational, are based on the same algorithm as the parameters in the corresponding TCDRs (CFC from CLAAS-2 and SIS from SARAH-2 ). The grid changed to a regular 0.05°x0.05° latitude/longitude grid and the internal file structure (number of data layers, name of fields) is also different. The file format will remain netCDF-4.

Test data are available at: ftp://ftp-cmsaf.dwd.de/ICDR_SEVIRI/eumetcast/
Users are recommended to adapt their systems as necessary.
The new ICDRs will be distributed on EUMETCast on the ‘SAF-Africa’ channel (PID: 301, Multicast address: 188.8.131.52). Users already subscribed to CM SAF products via EUMETCast will receive these new ICDRs automatically. Other users wishing to receive the products should register via our Earth Observation Portal (EOP).
The data distribution will start with the monthly mean products from May 2018 (actual distribution will be in June 2018). Users interested in receiving the equivalent data for the period January to April 2018 can order these via the CM SAF webpage (ICDR SEVIRI (cloud), ICDR SEVIRI (surface radiation products)).
