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.

  • MWIPP v1.0 released - February 6, 2019
    The initial version of the Microwave Imager Pre-Processor (MWIPP) has been released. This package processes microwave imager data from SSMIS, AMSR-2, GMI and MWRI, handling data in both hdf5 and BUFR formats. For details, please see the MWIPP web page.  
  • Associate Scientist mission delivers improved infrared emissivity atlas for RTTOV - January 23, 2019
    A recent associate scientist mission hosted by the University of Wisconsin has improved the global land surface infrared emissivity atlas for RTTOV v12.3 (the next release) which should enable more accurate simulations over land for infrared sounders. The current version of the RTTOV v12 CAMEL module is based on the NASA MEaSUREs CAMEL monthly mean land surface emissivity database for the single year of 2007. The new atlas is based on the full CAMEL climatology for 2000 to 2016. It provides a more sophisticated treatment of snow, and includes emissivity standard deviations computed from the climatology. More information can be […]
  • The NWP SAF is celebrating its 20th Anniversary! - November 28, 2018
    The NWP SAF has reached an important milestone this week. Twenty years ago, on 25 November 1998, the agreement was signed for the creation of the SAF on Numerical Weather Prediction. It was led by the UK Met Office with ECMWF, Météo France and KNMI as partners. Following a period of development, the NWP SAF became operational in 2004, and has been providing satellite data processing software and monitoring services to users ever since. In the latest phase DWD joined the SAF, replacing KNMI which consolidated its NWP activities in the OSI SAF. The focus of the NWP SAF over […]
  • AAPP v8.3 released - November 19, 2018
    AAPP update v8.3 has been released. The main changes are: (i) to support Metop-C (e.g. instrument calibration files), and (ii) to provide a VIIRS to CrIS clusters analysis, which was a request of the International TOVS Study Conference. For details, please see the Release Note.
  • Registration deadline extended for NWP SAF Satellite Data Assimilation Training Course 2019 - November 15, 2018
    The registration deadline for the The NWP SAF Satellite Data Assimilation Training Course 2019 has been extended to 15th December 2018.
