Since May 2018 CM SAF provides ICDR surface radiation products from SEVIRI based on SARAH-2 algorithms (with products since January 2018). Following a successful Operational Readiness Review (ORR), we are happy to announce that the product portfolio has been extended. For the parameters Surface Incoming Shortwave radiation (SIS), Surface Incoming Direct radiation (SID) and Direct Normalized Irradiance (DNI) CM SAF now also provides the instantaneous products in half-hourly resolution (with a timeliness requirement of 5 days). Additionally, daily and monthly sums of sunshine duration (SDU) are now available as a new ICDR product (timeliness requirement of 15 days). All products are provided on a 0.05°x0.05° lat/lon grid. In order to have a smooth transition to the respective TCDR, these products are provided starting from January 2018.
Following the successful ORR and approval by CM SAF steering group, the products DNI, SID, SIS and SDU have also been declared “operational”.
