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.

  • New domain - July 7, 2020
    The NWP SAF website has moved to a new domain, https://nwp-saf.eumetsat.int/. Please use this url in future. The structure of the site remains the same so urls may be edited such that www.nwpsaf.eu is replaced with nwp-saf.eumetsat.int/ e.g. https://www.nwpsaf.eu/site/software/rttov/ becomes https://nwp-saf.eumetsat.int/site/software/rttov/
  • NWP SAF is moving domain today - July 7, 2020
    Please see https://www.nwpsaf.eu/site/the-nwp-saf-is-moving-domain/. Whilst we are working on this no new user accounts may be created and the Help Desk will be inaccessible. We hope to have these functions restored by 14:00 UTC.
  • The NWP SAF is moving domain - July 2, 2020
    On Tuesday the 7th of July the NWP SAF will be moving domain to https://nwp-saf.eumetsat.int/. The purpose of this change is to provide a consistent identity across all of the EUMETSAT SAFs. This change will take place between the hours of 09:00 BST – 15:00 BST (08:00 UTC – 14:00 UTC). During this period, new account registrations and the helpdesk will be disabled. After the domain switch is complete, https://nwpsaf.eu/ will redirect to https://nwp-saf.eumetsat.int/. We will make a further announcement when the change is complete and the helpdesk and account registrations have resumed operation. Thank you for your cooperation during […]
  • 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.
  • NWP SAF 1D-Var v1.2 has been released - June 5, 2020
    The new version allows the retrieval of surface emissivity from a subset of IASI channels simultaneously with atmospheric profile information. This retrieval uses principal components of the emissivity and a background from an atlas . See the 1D-Var pages for more information.
