Satellite Application Facility for Numerical Weather Prediction

The NWP SAF is a EUMETSAT-funded activity that exists to co-ordinate research and development efforts among the SAF partners to improve the interface between satellite data and NWP for the benefit of EUMETSAT member states. The NWP SAF is led by the Met Office, with partners ECMWF, KNMI and Météo-France. More about the aims of the NWP SAF.

 NWP SAF deliverables
The SAF is concerned with the NWP data assimilation process rather than with generating geophysical parameters. Its main deliverables are software packages and data monitoring reports.
