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.

Recent News and Updates

  • 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).
  • Radiance Simulator v3.0 released - June 2, 2021
    Radiance Simulator v3.0 has been released. The main new features are: support for RTTOV v13.0, simulation of satellite footprints, ingest of fields from the HARMONIE model in GRIB format, ingest of fields from JMA in GRIB format (clear-sky simulations only), new script to generate obs data files for geostationary sensors, new optional outputs including surface Jacobians, and channel height assignments consistent with the NWP SAF CADS package. A full list of updates is available here.
  • Doppler wind LIDAR monthly monitoring available - May 21, 2021
    Monthly monitoring plots for ESA’s Aeolus mission are now avaiable on the winds quality evaluation area. Please visit the doppler wind quality evaluation monitoring page for more information.
  • FSOi monitoring available - April 12, 2021
    Meteo-France’s FSOi diagnostic (Forecast Sensitivity to the Observations derived impact) estimates the contribution of observations to the reduction of the forecast error and, therefore, its quality. Please visit the DAE Diagnostics webpage for further information.
  • AAPP v8.7 released. - February 4, 2021
    AAPP update 8.7 has been released. This includes calibration updates, DBNet station updates and improvements for working with historical data. For details, please see the Release Note that is available at
