• H15 - Blended SEVIRI Convection area/ LEO MW Convective Precipitation

will continue till the 31st of January 2023 before being officially discontinued.

Dear users,
after the start of the Full dissemination of the new precipitation products

• H60B- Blended SEVIRI / LEO MW precipitation and morphologic information
• H61B- Accumulated Precipitation at ground by blended MW and IR

the parallel dissemination of products:

• H05B - Accumulated precipitation at ground by blended MW+IR
• H03B - Precipitation rate at ground by GEO/IR supported by LEO/MW
• H15 - Blended SEVIRI Convection area/ LEO MW Convective Precipitation

will continue till a date that will announced in the next days before being officially discontinued

Today the EUMETCast Full dissemination of the following precipitation products has started and they are now officially released:

• P-AC-SEVIRI_E - Accumulated Precipitation at ground by blended MW and IR over IODC area
• P-IN-PMW - Gridded MW instantaneous precipitation rate based on intercalibrated PMW instantaneous precipitation rate
• P-AC-SM2RAIN - Precipitation/Soil Moisture integrated product
• P-AC-SEVIRI-PMW - Accumulated Precipitation at ground by blended MW and IR
• P-IN-SEVIRI-PMW - Blended SEVIRI / LEO MW precipitation estimates

The EUMETCast Full dissemination of the Pre-Operational precipitation product H90 (P-AC-SEVIRI_E) will start the 09/06/2022.

The H SAF H90 product (P-AC-SEVIRI_E) is the Accumulated Precipitation at ground by blended MW and IR over IODC area.

H90 integrates the instantaneous precipitation maps generated by P-IN-SEVIRI-E product (based on inter-calibrated Level 2 PMW instantaneous precipitation rate estimates blended with 10.8 μm channel from SEVIRI IODC 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 H63 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 H90 (the integration) could accentuate discontinuities between adjacent boxes. The problem is currently under resolution.

The EUMETCast Full dissemination of the Operational Precipitation product H68 (P-IN-PMW will start the 09/06/2022.The H SAF H68 product (P-IN-PMW) is the Gridded MW instantaneous precipitation rate based on intercalibrated PMW instantaneous precipitation rate estimates on extended H SAF area. This is a 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 MSG extended H SAF area are considered, to provide one unique precipitation rate estimate in each grid-box.

The EUMETCast Full dissemination of the Operational Precipitation product H64 (P-AC-SM2RAIN) will start the 09/06/2022.

The H SAF H64 product (P-AC-SM2RAIN) is the Precipitation/Soil Moisture integrated product. This products provides Gridded daily precipitation obtained by merging soil moisture-derived rainfall, obtained through the application of SM2RAIN to the SSMASCAT-A/B-NRT-O12.5 (H16 and H101, H104) soil moisture products, with the H-AUX-23 or H-AUX-67 rainfall estimates.

The EUMETCast Full dissemination of the Operational Precipitation product H60 (P-IN-SEVIRI_E) will start the 09/06/2022.

The H SAF 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 Low Earth Orbit (LEO) satellites, processed soon 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.

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.

The EUMETCast Full dissemination of the Operational precipitation product H60 (P-IN-SEVIRI-PMW) will start the 09/06/2022.

The H SAF H60 product (P-IN-SEVIRI-PMW) is the Blended SEVIRI / LEO MW precipitation estimates. Instantaneous precipitation maps are 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. 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.

Dear SSM product user,
the Metop-A satellite, launched on 19 October 2006, has massively exceeded its design lifetime of five years. However, it is now time for it to retire and this action is planned for November 2021. As a result Metop-A ASCAT SSM products (H101, H102) will be discontinued. The planned end date for the Metop-A ASCAT SSM products is 15th November 2021.
We will continue to provide ASCAT SSM from Metop-B and Metop-C. More detailed information can be found on https://www.eumetsat.int/plans-metop-end-life.

The H SAF snow products H34 (Snow detection by VIS/NIR of SEVIRI) and H35 (Snow detection and Effective snow cover by VIS/NIR of AVHRR) are now released in pre-operational status.

Dear users, from the 7th June 2021, products H01 (Precipitation rate at ground by MW conical scanners) and H02B (Precipitation rate at ground by MW cross-track scanners) will be disseminated only in NETCDF format. The dissemination of the BUFR format will be interrupted.

The H SAF is pleased to announce the Full dissemination for the following “Pre-Operational” Near-Real-Time products which is planned to start on 20/05/2021.

• (H34) Snow detection (snow mask) by VIS/NIR of SEVIRI, provides a binary map of snow / no-snow situation based on the acquisition of VIS/IR images from GEO;
