<p class="MsoNormal" style="text-align: justify;">The operational
data assimilation system of Météo-France uses a Four-Dimensional
Variational scheme (4DVAR), performed on 6h time windows. The 4DVAR
scheme provides the initial state of a global spectral forecasting
model called “ARPEGE” with a T798 horizontal resolution, 70 levels in
the vertical.<span style=""> </span>The assimilation makes a massive
use of satellite data, namely atmospheric motion vectors from
geostationary platforms and from MODIS, radiances from HIRS, AMSU,
AIRS, IASI and SEVIRI, scatterometer data, GPS radio-occultation
bending angles. In the seminar, latest developments on the use of
cloudy AIRS and IASI radiances, on the use of microwave radiances over
land and sea-ice, and on the preparation for the use of SSMIS data will
be presented. Furthermore, the Concordiasi field campaign planned over
Antarctica for September-November 2010 will be presented. Its main
scientific objectives are the validation of the use of satellite data
and the understanding of ozone depletion linked with gravity-wave
activity and Polar Stratospheric Clouds.</p>
