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

  • AAPP v8.2 released - May 10, 2018
    AAPP v8.2 has been  released. This is an AAPP update release. The main changes are to support new FY-3 BUFR sequences (already used in GTS data dissemination) and to update the NOAA-20 capabilities. Note that 2 new test cases are available to demonstrate these functions.
  • RTTOV v12.2 released - April 6, 2018
    RTTOV v12.2 has been released. Updates from the previous version, v12.1, include the option to run the MFASIS fast visible cloud parameterisation, new visible/IR cloud liquid water optical properties expressed in terms of particle size, RTTOV-SCATT updates (calculations in terms of radiance instead of brightness temperature, optional output data enabling dynamic all-sky emissivity retrievals, new optical properties for cloud liquid water and non-spherical particles), a new solar sea BRDF option, new MW cloud liquid water permittivity parameterisations, new PC-RTTOV coefficients enabling all trace gases and aerosols, and a much improved implementation of the HTFRTC PC-based model in RTTOV. See the […]
  • 8th Analysis Report of the NWP SAF AMV Monitoring - March 8, 2018
    The 8th Analysis Report of the NWP SAF AMV monitoring has been released and is available from the AMV monitoring webpages. The Analysis Reports document features seen in O-B monitoring of AMVs and where possible offer an explanation of these features. The 8th Analysis Report covers new datasets and changes to existing datasets since the 13th International Winds Workshop.
  • Release of new NWP SAF ERA-5 satellite monitoring - March 7, 2018
    Satellite monitoring time-series using ERA-5 as the reference atmospheric state are now available on the ECMWF monitoring site, and linked from the Monitoring overview page. Atmospheric states produced by re-analysis projects are generated using a fixed state-of-the-art NWP system applied to historical observations. As such they provide a much more suitable reference against which we can assess the quality of a satellite over its lifetime. To support users involved in climate applications, long timeseries quality statistics for satellites monitored against the ERA-5 reference have been included as an additional option to the existing operational monitoring web pages. ERA-5 replaces ERA-Interim […]
  • OPS-LRS v8.0 released - February 26, 2018
    This is a new release of the IASI level 1 processor OPS-LRS. It incorporates the latest OPS release from CNES, and addresses two issues that are listed on the AAPP “bugs” page. There is no change to the scientific content of the package or the way it is run. Note, to download OPS-LRS v8.0 you will first have to modify your software preferences: Select “Software Downloads” (at top of page) then click on “Change Software Preferences” and tick the box for OPS-LRS v8. The example AAPP build script has been updated to use OPS-LRS v8.0.
