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
- 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. - AAPP v8.11 released - February 2, 2023
AAPP update 8.11 has been released. The update includes a calibration update for Metop-B AMSU-A, support for NOAA-21 VIIRS to CrIS mapping and an option to use ECMWF forecast files in MAIA. For details, see https://nwp-saf.eumetsat.int/site/software/aapp/documentation/release-history/. - RTTOV v13.2 released - December 1, 2022
RTTOV v13.2 has been released. Updates from v13.1 include: new MFASIS neural network fast solver for visible/near-IR cloud radiances, alternative physically-based treatment of polarisation applicable to cross-track scanners and imagers in RTTOV-SCATT, new microwave sea surface emissivity model SURFEM-Ocean based on new community physical surface model PARMIO, new option to input per-channel effective skin temperatures, new option to account for molecular depolarisation in the Rayleigh phase function, new subroutines to compute solar zenith and azimuth angles and geostationary satellite zenith and azimuth angles, and various other updates and improvements. See the RTTOV pages for more information. - PenWP v4.0 released - October 14, 2022
Version 4.0 of the Pencil beam scatterometer Wind Processor has been released. As compared to previous release 2.2, PenWP version 4.0 can process data from the Haiyang-2B/C/D satellites. The new NSCAT-4DS Geophysical Model Function is included for improved consistency between Ku-band wind retrievals and C-band wind retrievals and buoy winds. Sea Surface Temperature dependent adjustments to the backscatter can be applied to reduce wind speed biases. Improved and New Quality Control flags have been introduced. The backscatter calibrations have been tuned for the generation of climate data records from QuikSCAT, RapidScat and Oceansat-2.
