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
  • SDP version 2.2 has been released. Compared to the previous version 2.1, the new version includes improvements in the Quality Control and improvement of the wind retrieval at low wind speeds. It uses the NSCAT-4 Geophysical Model Function for reduced wind speed bias at high wind speeds. SDP v2.2 is being used to create the climate data record for QuikSCAT in the OSI SAF. 02 October 2014.
  • AAPP update 7.7 has been released. This includes tools for working with sensor data record files from the new MWTS2 and MWHS2 instruments on Feng-Yun 3C. More information is available on the AAPP pages. 27 Aug 2014.
  • NWPSAF 1D-Var v1.0 has been released. This new version contains the merged capabilities of the now retired Met Office, SSMIS and ECMWF 1D-Var schemes. There is also now a graphical user interface (GUI) which produces plots of retrieval results and makes the installation and running of the software more straightforward. Further details can be found on the NWPSAF 1D-Var page 26 Aug 2014.
  • RTTOV 11.2 has been released. Changes from the previous release v11.1 include a new GUI, FASTEM-6, an update to the Baran ice particle optical property parameterisation for IR cloudy simulations, new internal interpolator options and other enhancements and bug-fixes. See the RTTOV pages for more information. 17 June 2014.
