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.
 NWP SAF news
  • AAPP update 7.10 has been released. The main change is the addition of VIIRS to CrIS mapping software. More information is available on the AAPP pages. 16 Jun 2015.
  • The first public beta version of the Pencil beam Wind Processor (PenWP) is ready for release by the EUMETSAT Numerical Weather Prediction SAF. PenWP generates surface winds from backscatter data from the SeaWinds (on QuikSCAT or ADEOS-II), OSCAT (on Oceansat-2), HSCAT (on HY-2A) and RapidScat (on the International Space Station) scatterometer instruments.
    We invite you to become a beta user of the PenWP software package. If you are interested, please email 09 Jun 2015.
  • AAPP update 7.9 has been released. This includes a new version of the MAIA4 cloud mask for VIIRS. A new feature is that MAIA4 can accept model background fields from the GFS model - available via the internet. More information is available on the AAPP pages. 24 Feb 2015.
  • Version 2.1 of the Aerosol and Cloud Detection Software has been released. As a new feature, the software makes use of collocated imager information to assist the cloud detection for IASI radiances. See the Cloud Detection Software pages for more information. 19 Feb 2015.

 Visiting scientists

A visiting scientist programme allows scientists from institutions that are not SAF members to participate in the activities of the SAF. More about visiting scientists.
