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 Met Office 1D-Var v3.4 has been released. This new version adds support for the RTTOV v10 radiative transfer model and the addition of SSMIS liquid water retrieval capability. Further details can be found on the Met Office 1D-Var page. 11 May 2012. New monitoring pages showing plots of SSMIS and AIRS radiances vs Met Office global NWP are now available. Links to additional external monitoring sites have also been added to the monitoring links webpage. 18 April 2012. EUMETSAT has extended the duration of support services to licensees of NWP SAF software. For further details see the Software Request Forms page. 2 March 2012. AAPP version 7.1 has been released. The new version introduces capability to process Sensor Data Record (SDR) data from the Advanced Technology Microwave Sounder (ATMS) and Cross-track Infrared Sounder (CrIS) on the Suomi NPP satellite, as well as bug fixes and other enhancements. New users, and existing users of AAPP v6, can access the package by registering here. More information can be found on the AAPP pages. 2 March 2012.  Further news items can be seen on the NWP SAF News page.	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.
