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.

  • AWDP v3.1 released - May 30, 2017
    AWDP v3.1 has been released. This minor release of the ASCAT and ERS scatterometer wind data processor includes flow-dependent errors in 2DVAR for the ASCAT coastal product. If activated, the scatterometer and background errors in 2DVAR are set according to the values of the MLE and the singularity exponent, leading to slightly improved wind statistics […]
  • Radiance Simulator v2 released - May 10, 2017
    Radiance Simulator v2 has been released. The code has a number of enhancements over the previous version, including; support for RTTOV v12, input profile batching (to enable simulation of very large datasets), support for emissivity atlases, land-sea-mask interpolation and other improvements and bugfixes. Please see the Radiance Simulator webpages for further information.
  • Start of CDOP-3 - March 1, 2017
    Start of CDOP-3, the third Continuous Development and Operations Phase. The Met Office continues to lead the NWP SAF, with partners ECMWF, Météo-France and Deutscher Wetterdienst.
  • PenWP v2.1 released - February 28, 2017
    PenWP v2.1 has been released in February 2017. This version of the Ku-band pencil beam scatterometer wind data processor can process OSCAT data from ScatSat-1. In the Ambiguity Removal step, empirical background error correlations (NBECs) can be used which yield improvements in the retrieved wind fields. Version 2.1 is also the version to be used […]
  • NWPSAF 1D-Var v1.1 released - February 27, 2017
    This is to announce the release of version 1.1 of the NWPSAF 1D-Var. The main new capabilities of this version are: Support for RTTOV v12 , enabling the most up-to-date RT capabilities (RTTOV 11.3 is also supported but older versions have now been removed). Ability to use PC-RTTOV to simulate PC scores from hyperspectral sounders, […]
