Abstract

Based on the MSG-CPP cloud products (cloud physical properties retrieved from Meteosat measurements) a forecast/nowcast of these cloud properties is made and converted to surface downwelling shortwave radiation. The nowcast is made using the pySTEPS optical flow method for an area covering Europe and a 4-hour time horizon with a 15-minute time step. The values are resampled on a lat-lon grid with a resolution of 0.05x0.05 degrees.
