Satellite data assimilation

Specific research is done to improve the use of satellite data over what is implemented by ECMWF for the IFS, for the benefit of the ARPEGE, ALADIN and AROME data assimilation systems. Satellite data assimilation is a fast moving area, with lots of good opportunities from new satellite instrument technologies. The work at GMAP is stimulated by strong cooperations with CNES, NESDIS, ECMWF, Eumetsat and ESA.
