12. 1st IPWG Workshop. Madrid 23-27 Sep 2002 The EUMETSAT SAF on Nowcasting & VSRF 12 Products: Convective Rainfall Rate CRR Based on RAINSAT methodology statistical relationship between satellite (multi-band imagery) and rainfall rate data obtained using radar data. CRR value for each pixel is obtained from calibration matrices. Calibration matrices are different if a pixel belongs to day or night mask. Day pixels CRR calibration data is a matrix 3-D (bands: IR10.8, WV6.2, VIS0.6.) Night pixels calibration values are stored in a 2-D matrix (bands: IR10.8, WV6.2.) Normalised visible counts are obtained using Binder algorithm. Smoothing process performed to eliminate stratiform rain data - not associated with convective clouds. The obtained CRR significant data are set to zero if all the nearest pixels in a box of 14x14 do not have an equal or higher value than 3mm/h.
