The EUMETCast Full dissemination of the Pre-Operational Precipitation product H61 (P-AC-SEVIRI-PMW) will start the 09/06/2022.

The H SAF H61 product (P-AC-SEVIRI-PMW) is the Accumulated Precipitation at ground by blended MW and IR. H61B integrates the instantaneous precipitation maps generated by P-IN-SEVIRI-PMW product (based on inter-calibrated Level 2 PMW instantaneous precipitation rate estimates blended with 10.8 μm channel from SEVIRI instrument). The integration is performed providing hourly the 1 hour accumulated precipitation and every six hours (at 00, 06, 12 and 18 UTC) the 24 hour accumulated precipitation. The "Pre-Operational" status is justified by the following limitation affecting the H61B product: the instantaneous product that combines the PMW precipitation estimation with GEO IR channel products on boxes of 2.5° in geographical latitude and longitude, and H61B (the integration) could accentuate discontinuities between adjacent boxes. The problem is currently under resolution.
