| Zusammenfassung |
| The Satellite Application Facility on Climate Monitoring (CM-SAF) aims at the
provision of satellite-derived geophysical parameter data sets suitable for
climate monitoring. CM-SAF provides climatologies for Essential Climate
Variables (ECV), as required by the Global Climate Observing System
implementation plan in support of the UNFCCC. Several cloud parameters,
surface albedo, radiation fluxes at the top of the atmosphere and at the
surface as well as atmospheric temperature and humidity products form a sound
basis for climate monitoring of the atmosphere. The products are categorized
in monitoring data sets obtained in near real time and data sets based on
carefully intercalibrated radiances. The CM-SAF products are derived from
several instruments on-board operational satellites in geostationary and
polar orbit as the Meteosat and NOAA satellites, respectively. The existing
data sets will be continued using data from the instruments on-board the new
joint NOAA/EUMETSAT Meteorological Operational Polar satellite. The products
have mostly been validated against several ground-based data sets both in
situ and remotely sensed. The accomplished accuracy for products derived in
near real time is sufficient to monitor variability on diurnal and seasonal
scales. The demands on accuracy increase the longer the considered time scale
is. Thus, interannual variability or trends can only be assessed if the
sensor data are corrected for jumps created by instrument changes on
successive satellites and more subtle effects like instrument and orbit drift
and also changes to the spectral response function of an instrument. Thus, a
central goal of the recently started Continuous Development and Operations
Phase of the CM-SAF (2007–2012) is to further improve all CM-SAF data
products to a quality level that allows for studies of interannual
variability. |
