Products
H64: Precipitation/Soil Moisture integrated product
The H64 product (P-AC-SM2RAIN) provides gridded daily precipitation obtained by merging soil moisture-derived rainfall with the SAF internal H-AUX-23 or H-AUX-67 rainfall estimates.

H68: Gridded MW instantaneous precipitation rate based on intercalibrated PMW instantaneous precipitation rate estimates
The H68 product (P-IN-PMW) provides gridded MW precipitation rate at regular time intervals. It is based on instantaneous precipitation rate estimates available from Precipitation rate at ground by MW conical scanners (H01 new rel.), Precipitation rate at ground by MW cross-track scanners (H02B), Precipitation rate at ground by MW cross-track scanners 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 MSG extended H SAF area are considered, to provide one unique precipitation rate estimate in each grid-box.

H63: Precipitation rate at ground by GEO/IR supported by LEO/MW IODC
The H63 product (P-IN-SEVIRI-E) is the blended SEVIRI/LEO MW precipitation estimates over IODC area.
Instantaneous precipitation maps are generated combining geostationary (GEO IODC) IR images from operational geostationary satellites 'calibrated' by precipitation measurements from MW images on LEO satellites, processed shortly after each acquisition of a new image from GEO IODC.
A separate treatment is performed for convective precipitation: the morphologic information and the enhancement of precipitation estimate is done by the use of NEFODINA software.

H90: Accumulated Precipitation at ground by blended MW and IR IODC
The H90 product (P-AC-SEVIRI_E) integrates the instantaneous precipitation maps generated by the H63 product (based on inter-calibrated Level 2 PMW instantaneous precipitation rate estimates blended with the 10.8 channel from IODC SEVIRI).
The integration is performed providing hourly the one hour accumulated precipitation and every six hours (at 00, 06, 12 and 18 UTC) the 24-hour accumulated precipitation.

H60B: Blended SEVIRI/LEO MW precipitation and morphologic information
The H60B product (P-IN-SEVIRI-PMW) provides instantaneous precipitation maps generated combining geostationary (GEO) IR images from operational geostationary satellites 'calibrated' by precipitation measurements from MW images on LEO satellites, processed shortly after each acquisition of a new image from GEO.
A separate treatment is performed for convective precipitation: the morphologic information and the enhancement of precipitation estimate is done by the use of NEFODINA software.
This product, after a six-month parallel dissemination, will replace H03B (Precipitation rate at ground by GEO/IR supported by LEO/MW) and H15A (Blended SEVIRI Convection area/LEO MW Convective Precipitation). Exact date will be communicated in due course.

H61B: Accumulated Precipitation at ground by blended MW and IR
The H61B product (P-AC-SEVIRI-PMW) integrates the instantaneous precipitation maps generated by the H60 product.
The integration is performed providing hourly the one hour accumulated precipitation and every six hours (at 00, 06, 12 and 18 UTC) the 24-hour accumulated precipitation.
This product, after a two-month parallel dissemination, will replace H05B (Accumulated precipitation at ground by blended MW+IR). Exact date will be communicated in due course.
Example filenames

All the above products have operational status, except for H90 and H61B which currently have pre-operational status. Those two products are pre-operational because combining the PMW precipitation estimation with GEO IR channel products on boxes of 2.5° in geographical latitude and longitude, in some particular cases, could accentuate discontinuities between adjacent boxes.
