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

  • Radiance Simulator v2.1has been released - June 20, 2018
    Radiance Simulator v2.1 has been released. The main new features are: support for RTTOV v12.2, temporal interpolation of model data to observation times, optional use of RTTOV parallel interfaces for multi-threaded simulations, more RTTOV options can be specified in the configuration file, output files now use netCDF-4 classic format with internal compression, and a new Python script which can be used to create configuration namelists and run RadSim from the command line.
  • CWDP v0.9 has been released - June 14, 2018
    The first beta version of the CFOSAT Wind Data Processor (CWDP) version 0.9 has been released in May 2018. CFOSAT is the French-Chinese ocean observation satellite, to be launched in autumn 2018. This software version can process simulated CFOSAT input data, a simulator is included. After launch a new CWDP version capable of processing real data will be released. We stimulate users to provide feedback, which will help us to improve the software in future releases. Note, this software is developed and supported by the OSI SAF and distributed by the NWP SAF.
  • PenWP v2.2 has been released - June 14, 2018
    PenWP v2.2 has been released in May 2018. This minor release of the Ku-band pencil beam scatterometer wind data processor includes an improved interface and handling of the 2DVAR Ambiguity Removal to streamline and simplify the processing. Moreover it is adapted to process OSCAT data from ScatSat-1(improved ISRO data version 1.1.3). Note, this software is developed and supported by the OSI SAF and distributed by the NWP SAF.
  • AWDP v3.2 has been released - June 14, 2018
    AWDP v3.2 has been released in May 2018. This minor release of the ASCAT and ERS scatterometer wind data processor includes an improved interface and handling of the 2DVAR Ambiguity Removal to streamline and simplify the processing. Note, this software is developed and supported by the OSI SAF and distributed by the NWP SAF.
  • 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.
