Satellite Application Facility for Numerical Weather Prediction

The NWP SAF aims to improve and support the interface between satellite data/products and European activities in NWP.

The NWP SAF is one of several EUMETSAT SAFs (Satellite Application Facilities). Utilising specialist expertise from the Member States, SAFs are dedicated centres of excellence for processing satellite data and form an integral part of the distributed EUMETSAT Application Ground Segment. Further information about SAFs is available on the EUMETSAT web site.

The SAF for NWP interacts, where appropriate, with related work in other SAFs and in other EUMETSAT activities in order to enhance collaboration and to minimise duplication of effort.

  • Training course: EUMETSAT/ECMWF NWP-SAF satellite data assimilation - September 15, 2021
    This 5-day course provides a complete overview of the usage of meteorological satellite observations in operational numerical weather prediction (NWP). It includes a series of lectures and practical sessions covering a range of topics – from fundamental theoretical concepts through to detailed practical implementations in modern state-of-the-art data assimilation systems. The course will take place from 7 to 11 March 2022 at ECMWF headquarters in Reading (UK). There is no course fee for this course. Registration closes: 29 October 2021 For more information, please see:
  • Data Reception Routes - September 13, 2021
    A new page, Data Reception Routes, summarises the routes via which data are received at DWD and MetOffice respectively. For some data types different reception routes are available and used at DWD and the MetOffice.
  • AAPP update 8.8 has been released. - August 24, 2021
    AAPP update 8.8 has been released. This update includes portability fixes (for gcc 8), DBNet station updates and a bug fix for HIRS processing. For details, see
  • NRT availability monitoring update - August 23, 2021
    The near-real-time data availability monitoring has been extended to provide coverage and timeliness plots based on DWD reception for the scatterometer on HY-2B and HY-2C (referred to as HSCAT) and also plots for geostationary ASR data streams additionally to the CSR data streams. Please visit the NRT availability monitoring web pages to access the plots.
  • MWRI DBNet monitoring page added - June 2, 2021
    DBNet monitoring is now being performed for FY-3D MWRI, see monitoring page. In addition, an update has been made to the monitoring software. In future, this should eliminate the occasional cases seen of incorrect DBNet-global scanline matching, which has resulted in plots displaying a few scanlines with very large navigational differences (as well as sections of the overpass with large BTDs).
