• 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.

6-hourly SEVIRI images (10.8 µm channel) at 00,
06, 12, 18 and 24 UTC and the corresponding 24-h
accumulated precipitation (PR-OBS-5). 1st
February 2008. 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.

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.

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?namehsaf. It
contains, i.a. - ATDD-2.0 (Algorithms
Theoretical Definition Document - PUM-1.0
