Characteristics and Methods
Level 3 product providing gridded MW precipitation rate at regular time intervals. It is based on instantaneous precipitation rate estimates available from P-IN-SSMIS (H01), P-IN-MHS (H02B), P-IN-ATMS (H18), H-AUX-17, H-AUX-20, combined and intercalibrated. For each 30 minute time interval, all orbits of LEO satellite carrying PMW radiometers (SSMIS, AMSR-2, GMI, ATMS, AMSU/MHS) available over the extended H SAF area are considered, to provide one unique precipitation rate estimate in each grid-box.
Validation method
Meteorological radar and rain gauge; use of GPM DPR over Africa and Southern Atlantic.
