The EUMETSAT Satellite Application Facility (SAF) on support to operational hydrology and water management (H SAF) was established by the EUMETSAT Council in July 2005 and the Development phase started on 1st September 2005.
H SAF membership includes 12 EUMETSAT member or cooperating States (Austria, Belgium, Bulgaria, Finland, France, Germany, Hungary, Italy, Poland, Romania, Slovakia and Turkey) and ECMWF. The H SAF is hosted by the Italian Met Service.
In the framework of the H SAF the interest for new satellite products focuses on:
- Precipitation rate and cumulate precipitation, including liquid/solid discrimination;
- Soil moisture in the surface layer and possibly in the roots region;
- Snow parameters such as effective cover, wet/dry discrimination, water equivalent.
ECMWF is a contributor to the core soil moisture product and is represented in the H SAF Steering Group and the Project Team.
