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.

  • NRT data availability montioring for Aeolus HLOS winds - June 10, 2020
    The near-real-time data availability monitoring has been extended to provide coverage and timeliness plots based on DWD reception for the horizontal line-of-sight (HLOS) winds from the ALADIN Doppler Lidar on Aeolus (operationally disseminated since mid May). Please visit the NRT availability monitoring web pages to access the plots.
