INTRODUCTION
Two ENAMORS objectives are especially relevant with respect to
meteorological remote sensing activities: the validation of operational
remote sensing products and the identification of further actions in
methodological research for the development of novel applications, in
particular in the framework of new European meteorological geostationary
satellites. These two activities are closely related since validation is an
important phase of new algorithm design. This paper covers therefore these
two different topics. In section 2, the current Meteorological Product
Extraction Facility (MPEF) exploited at EUMETSAT is presented and the
problem of validation and operational quality control addressed.
The characteristics of the Meteosat Second Generation (MSG), the new
European meteorological geostationary satellite to be launched in 2000, are
presented in section 3. Its potential for the monitoring of land surfaces is
explored. Albeit MSG spectral characteristics are similar to the
NOAA/AVHRR instrument, the observation sampling is completely
different. The additional information conveyed by the frequent observations
is illustrated with a simple example. It turns out that an optimal exploitation
of geostationary observations will require dedicated retrieval algorithms.
