New CM SAF ICDRs of Fractional Cloud Cover and Surface Incoming Shortwave Radiation will replace the Environmental Data Records of these products currently available on EUMETCast.
Wednesday, 07 February 2018
In March (exact date to be confirmed), CM SAF will discontinue the processing of the SEVIRI-based Environmental Data Record (EDR) of Fractional Cloud Cover (CFC) and Surface Incoming Shortwave Radiation (SIS).
They will be 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 will be based on the same algorithm as the parameters in the corresponding TCDRs (CFC from CLAAS-2 and SIS from SARAH-2 ). The grid will change to a regular 0.05°x0.05° latitude/longitude grid and the internal file structure (number of data layers, name of fields) will also be different. The file format will remain netCDF-4.
More information on the changes and links to related product documentation can be found in the document: Changes in SEVIRI-based, routinely provided EDR products.
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: 126.96.36.199). 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).
