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

  • 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, […]
  • AAPP update 7.15 released - February 23, 2017
    AAPP update 7.15 has been released. The changes include an update to the MAIA4 VIIRS cloud mask and inclusion of AAPP version numbers in BUFR products (requested by the DBNet Coordination Group).
  • AWDP v3.0 released - February 23, 2017
    AWDP v3.0 has been released. This version of the ASCAT and ERS scatterometer wind data processor features processing of ASCAT data on an optimized 5.6 km grid which is synchronized with the mid beam antenna pattern, resulting in better high resolution wind retrievals. In the Ambiguity Removal step, empirical background error correlations can be used […]
  • RTTOV v12 released - February 22, 2017
    RTTOV v12 has been publicly released. Updates from the previous version, v11.3, include a new visible/IR multiple scattering solver, updates to visible/IR ice cloud optical properties, new IR and MW sea surface emissivity models and land surface emissivity atlases, new coefficients allowing SO2 as a variable trace gas, updated non-LTE correction, new PC-RTTOV coefficients allowing […]
