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

  • NRT availability monitoring update - May 25, 2023
    The near-real-time data availability monitoring has been updated to provide coverage and timeliness plots based on DWD reception for the geostationary radiances and AMVs from Himawari-9, GOES-18, MTEOSAT-10 as well as microwave radiances from MWTS-3 and MWHS-2 on the early morning orbit satellite FY-3E. Please visit the NRT availability monitoring web pages to access the plots
  • 10th Analysis Report of the NWP SAF AMV Monitoring - May 24, 2023
    The 10th Analysis Report of the NWP SAF AMV monitoring has been released and is available from the Analysis Reports section of the AMV monitoring webpages ( The analysis reports identify features from the monitoring statistics and document how these evolve over time. Where possible attempts are made to diagnose the cause of the difference between the AMVs and the model. This edition includes the use of the NWC SAF software package to look at two AMV case studies in the Tropical East African region, namely mesoscale convective systems and winds in the boundary layer.
  • NWP SAF Satellite Data Assimilation Training Course - May 10, 2023
    The next NWP SAF satellite data assimilation training course will take place at ECMWF, Reading, on 15-19 May 2023. The course provides a complete overview of the usage of meteorological satellite observations in operational numerical weather prediction (NWP). It includes a series of lectures and practical sessions covering a range of topics – from fundamental theoretical concepts through to detailed practical implementations in modern state-of-the-art data assimilation systems. Registration for this course is closed but lecture notes and course materials are available online. More information on
  • MWIPP v1.2 released - February 14, 2023
    This is an update release of the Microwave Imager Pre-processor (MWIPP). The main purpose of the update is to support MWI/ICI test data issued by EUMETSAT in November 2022. Also, some corrections have been made to the AMSR-2 solar angles. For details, please see the Release Note on the MWIPP web page.
  • IRSPP v1.2 released - February 2, 2023
    This is an update release of the InfraRed Sounder Pre-processor (IRSPP). Changes have been made to ensure compatibility with the set of MTG-IRS test data that was issued by EUMETSAT in November 2022. Also, some extra thinning options have been provided. For details, please see the Release Note on the IRSPP web page.
