Recent process in the use of AMVs in the MSC deterministic prediction systems
The use of quality indicators coefficients for geostationary satellites at EC is being reviewed and validated. Currently, both EUMETSAT QI and CMISS/NESDIS RFF are employed to select AMV observations. In addition, the temporal thinning of AMV's is another important issue that is examined. Hourly GOES AMVs have also been evaluated. The impact of assimilating this product on hourly, 2-hourly and 3-hourly basis will also be presented. As well, another objective at MSC is to assimilate AMV's over the Northern Hemisphere continents and beyond 55 degrees zenith angle.
