  3. Objectives of H-SAF • The objectives of H-SAF are: • to provide new satellite-derived products: • - precipitation (liquid, solid, rate, cumulate) • - soil moisture (at surface, in the roots region) • - snow parameters (cover, melting conditions, water equivalent); • to perform independent validation of the usefulness of the new products for hydrological applications.

Maps for the accumulated precipitation in the previous 3, 6, 12 and 24 h are generated each 3 hours PR-OBS-5 is routinely available at ftp://ftp.meteoam.it. IPWG, 4th Workshop, Beijing, 13-17 October 2008

  16. Instantaneous precipitation on 8 February 2008 at 00 UTC and accumulated precipitation in the previous 24 h, computed by the COSMO-ME NWP model. Each 3 hours the model generates the map of instantaneous precipitation (at 00, 03, 06, 09, 12, 15, 18, 21 UTC) and the maps of accumulated precipitation in the previous 3, 6, 12 and 24 hours. PR-ASS-1 is routinely available at ftp://ftp.meteoam.it. IPWG, 4th Workshop, Beijing, 13-17 October 2008

  17. CONCLUSIONS The H-SAF Development Phase (2005-2010) is now running since 3 years. Of the envisaged 6 precipitation products, 5 are being generated routinely. The missing one (PR-OBS-4, the MW/IR blending by “morphing”) is expected to be ready in mid-2009. However, according to the developer (Vincenzo Levizzani), the capability to meet operational requirements (specifically timeliness) is not sure. Data are used by the Product validation teams and for impact studies in the Hydrological validation programme. All products can be accessed from the Italian Meteorological Service ftp site. Access is restricted to beta users (username and password needed), but IPWG members are entitled to get access. The H-SAF web site is open: http://www.meteoam.it/modules.php?name=hsaf. It contains, i.a.: - ATDD-2.0 (Algorithms Theoretical Definition Document - PUM-1.0 (Products User Manual). IPWG, 4th Workshop, Beijing, 13-17 October 2008
