P-IN-SSMIS (H01)
Precipitation rate at ground by MW cross track scanners
operational
Instantaneous precipitation maps from PMW acquisitions by conical scanners on operational LEO satellites, processed soon after each satellite pass. Retrieval algorithm based on physically-based Bayesian approach supported by a pre computed cloud/dynamic-radiation database built from meteorological situations simulated by a cloud resolving model followed by a radiative transfer model.

operational
Instantaneous precipitation maps from PMW acquisitions by cross-track scanners on operational LEO satellites, processed soon after each satellite pass. Retrieval algorithm based on a neural network trained by means of a pre-computed cloud radiation database built from meteorological situations simulated by a cloud resolving model followed by a radiative transfer model

P-IN-SEVIRI (H03B)
Precipitation rate at ground by blended MW and IR
operational
Instantaneous precipitation maps by IR images from operational geostationary satellites “calibrated” by precipitation measurements from PMW satellite sensors in sun-synchronous orbits, processed soon after each GEO acquisition. The calibrating lookup tables are updated after each new pass of a MW-equipped satellite

P-AC-SEVIRI (H05B)
Accumulated precipitation at ground by blended MW and IR
operational
Accumulated precipitation by merging MW images from operational sun-synchronous satellites and IR images from GEO satellites (i.e., product P-IN-SEVIRI). Integration is performed over 3, 6, 12 and 24 h. In order to reduce biases, the satellite-derived field is forced to match raingauge observations

P-IN-SEVIRI-CO (H15)
Blended SEVIRI Convection area / LEO MW Convective Precipitation
operational
Instantaneous precipitation maps by IR images from operational geostationary satellites “calibrated” by precipitation estimates from MW radiometers on board LEO satellites, processed soon after each GEO acquisition. The calibrating lookup tables are updated after each new pass of a MW-equipped satellite

P-IN-ATMS (H18)
Precipitation rate at ground by MW cross track scanners
operational
Precipitation rate at ground for the MSG/MTG full disk area from cross-track scanning radiometer ATMS on board the NOAA/NASA Suomi-NPP LEO satellite, processed soon after data availability. The product is based on the Neural Network approach (as used in P-IN-MHS product)

P-IN-SEVIRI-PMW (H60B)
Blended SEVIRI / LEO MW precipitation
operational
Instantaneous precipitation maps generated combining geostationary (GEO) IR images from operational geostationary satellites 'calibrated' by precipitation measurements from MW images on Low Earth Orbit (LEO) satellites, processed soon after each acquisition of a new image from GEO. The blending algorithm ('Rapid Update’) generates precipitation estimates combining the equivalent blackbody temperatures (TBB) at 10.8 μm with rain rates from all available Passive MW measurements. 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.

P-AC-SEVIRI-PMW (H61B)
Accumulated Precipitation at ground by blended MW and IR
operational
Near-real time product 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.

P-IN-SEVIRI_E (H63)
Precipitation rate at ground by GEO/IR supported by LEO/MW IODC
operational
Instantaneous precipitation maps over IODC area generated combining geostationary (GEO) IR images from operational geostationary satellites 'calibrated' by precipitation measurements from MW images on Low Earth Orbit (LEO) satellites, processed soon after each acquisition of a new image from GEO. The blending algorithm ('Rapid Update’) generates precipitation estimates combining the equivalent blackbody temperatures (TBB) at 10.8 μm with rain rates from all available Passive MW measurements.

P-AC-SM2RAIN (H64)
Precipitation/Soil Moisture integrated product
operational
Gridded daily precipitation obtained by merging soil moisture-derived rainfall with the H-AUX-23 rainfall estimates

P-IN-PMW (H68)
Gridded MW instantaneous precipitation rate based on intercalibrated PMW instantaneous precipitation rate estimates on extended H SAF area
operational
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.
