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
- AAPP v8.10 released - August 9, 2022
AAPP update 8.10 has been released. The update includes support for “version 2” IASI eigenvector files from EUMETSAT (due for implementation later in 2022) and support for FY-3E MWTS-3 and MWHS-2. There are also portability updates for gfortran10. For details, see https://nwp-saf.eumetsat.int/site/software/aapp/documentation/release-history/.
- IASI local versus global processing monitoring at Lannion - March 21, 2022
A new website http://nwpsaf.meteo-spatiale.fr/ provides comparison between local and global processing of IASI data. This includes L1C mean spectral differences in brightness temperature, maps of cloud fraction differences from IASI local overpasses and statistics as well as cloud type retrievals from AVHRR.
- Updates to DBNet station status page - March 16, 2022
The DBNet “Station Status” webpage now highlights any station data feeds with poor consistency with global data (as well as displaying reception status). Please refresh the cache if this page isn’t updating as expected (by pressing CTRL + F5 on a Windows browser). Additional data consistency email alerts are also now being sent to regional centre coordinators and station operators to warn of any new consistency failures.
- MWIPP v1.1 released - March 16, 2022
A new version of the Microwave Imager Pre-processor (MWIPP) has been released. The main change in version 1.1 is to support ingest and pre-processing of the MWI and ICI simulated data released by EUMETSAT in January 2021. For details, see the MWIPP web page.
- Web Based Satellite Sounding Training Application - March 15, 2022
NWP SAF users can now experiment with RTTOV simulations and 1D-Var retrievals directly online with the new Web Based Satellite Sounding Training Application https://sounding.trainhub.eumetsat.int/. A selection of satellite instruments and input profiles from the NWP SAF profile database are used for the simulation and the retrieval tools. Users can modify the temperature, humidity, observation and background errors, noise, satellite zenith angle, or surface emissivity, and see how it impacts simulations and retrievals. The tool can display the results of the K-Model (Jacobian) as well as the result of the Direct Model (brightness temperatures and radiances), and the differences between the […]
