Dear users,
Due to some user requests, the changes in the output format for the following precipitation products:
- H60B: Blended SEVIRI / LEO MW precipitation
- H61B: Accumulated Precipitation at ground by blended MW and IR
- H63: Precipitation rate at ground by GEO/IR supported by LEO/MW IODC
- H90: Accumulated Precipitation at ground by blended MW and IR IODC
is postponed to the 1st of July 2025 (not the 6th May as previously announced).
- The precipitation rate values will be stored as integer values (decimillimetres rain per hour) instead of the current real values (millimetres rain per hour), having a scale factor (scale_factor) of 0.1 and an offset (add_offset) of 0.0.
- The undefined values (missing_values) are stored with the value of -99.
- In addition to the mentioned changes, in order to promote the processing and sharing of files created with the NetCDF API, the new files will be CF compliant. In this respect, we highlight the major change that will impact the operational use of the these products that is the invertion of the dimensions (y first , x last).
This new format will reduce significantly the products files dimension bringing benefits in terms of NRT files download via FTP and orders placing.
The test data for format familiarisation and system testing can be accessed starting from the 15th of May from our ftp site:

Dear Users, due to technical issues the distribution of the new format for precipitation products: H60B (Blended SEVIRI / LEO MW precipitation), H61B (Accumulated Precipitation at ground by blended MW and IR), H63 (Precipitation rate at ground by GEO/IR supported by LEO/MW IODC) and H90 (Accumulated Precipitation at ground by blended MW and IR IODC); is postponed to the 6th of May.

Due to a permanent and unrecoverable damage of the 50 GHz channel, the DMSP18 satellite has been set out from the production of H01.
The last available orbit was 20241031_1219_DMSP18_77565

Dear users, we inform you that, product H120 SSM ASCAT DR2021 EXT TS12.5 has been updated and it now covers the period (2021-01-01 until 2024-08-31).

The Snow Water Equivalent by MW radiometry product H65 (SN-SWE-HH) has been released and it will now be avaulable on EUMETCast.
The H SAF H65 product (SN-SWE-HH) is gridded MW daily SWE observation for Northern Hemisphere. H65 is extension of H13 product to full Northern Hemisphere coverage with improved error estimates added.
The product is a merge between two approaches. For flatlands and forested areas snow depth data from weather stations are used to produce a first guess that is converted into MW brightness temperatures by an emission model.
An assimilation process is then used to force the first guess field to match MW brightness temperatures from SSMIS instrument aboard DMSP 18 satellite.
For mountainous areas, look up tables are used to fix any unrealistic snow density values retrieved from assimilating the satellite observations.
The H SAF H65 daily product is made available three days after each full Hemispheric coverage by SSMIS instument.
The product is offered in EASE2 equal area scalable earth grid, offering easy summation of liquid water volume over larger areas of interest.
