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.

Please visit the NRT availability monitoring webpages for further information.
- RTTOV v13.0 released - November 25, 2020
RTTOV v13.0 has been released. Updates from v12.3 include: new gas optical depth coefficients based on updated spectroscopy and new optical depth predictors; new “all trace gas” coefficients for various hyperspectral and non-hyperspectral VIS/IR sensors; for visible channels, a new parameterisation of Rayleigh extinction that may now optionally be excluded from simulations; option to treat Rayleigh multiple scattering in the DOM solver; updated VIS/IR cloud liquid water optical properties based on a newer refractive index dataset; new parameterisation for cloud liquid water effective diameter; optimisation of the MFASIS fast model and the DOM solver AD/K models; and RTTOV-SCATT updates to […]
- NWP SAF workshop on the treatment of random and systematic errors in satellite data assimilation for NWP - November 2, 2020
The ECMWF/NWP SAF workshop on the treatment of random and systematic errors in satellite data assimilation for NWP is currently taking place (2-5 November 2020) virtually, with livestreamed talks. You can find information on the workshop here, including links to the full programme and livestream.
- Timeliness plots and statistics for DBNet data - October 21, 2020
Timeliness plots and statistics for DBNet data are now generated daily and linked from the DBNet Monitoring “overview” page https://nwp-saf.eumetsat.int/site/monitoring/dbnet/. This is a preliminary service and further developments are planned in the coming months. It is expected that the information will be useful to both DBNet operators and NWP users.
