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.

Recent News and Updates

  • Radiance Simulator v2.2 released - September 26, 2019
    Radiance Simulator v2.2 has been released. The main new features are: support for RTTOV v12.3, simulations for all solar-affected channels supported by RTTOV including use of the BRDF atlas and the MFASIS fast visible cloud parameterisation, clear-sky simulations using the Principal Components-based models PC-RTTOV and HTFRTC, ingest of DWD ICON model fields in GRIB format, ingest of ECMWF data in netCDF format, and the ability to modify the background CO2 profile used in the simulations.
  • Upgraded NRT quality monitoring - September 5, 2019
    Near-real-time data quality monitoring pages have been upgraded and refreshed. A new monitoring system has been introduced at the Met Office and plots are now available for many new instruments and L2 products at multiple centres. Please visit the refreshed NRT quality monitoring webpage to access and explore the new monitoring plots.
  • DBNet monitoring for FY-3D - July 16, 2019
    The NWP SAF DBNet monitoring┬áhas been extended to cover data from the MWHS-2 and MWTS-2 instruments on the Chinese FY-3D satellite. These data are part of EUMETSAT’s EARS-VASS┬áservice. The FY-3D component is currently in trial dissemination mode, and the NWP SAF plots help to assure the quality of the data.
  • NRT data availability monitoring enhanced to include additional data types - June 25, 2019
    The near-real time data availability (coverage and timeliness) monitoring has been extended to include the data from METOP-C (AMSU-A, MHS, IASI, ASCAT and AMVs) as well as clear sky radiances from GOES-16 and altimeter winds from Sentinel-3 A and B. ATMS and CrIS from NOAA-20 have also been added to the NRT data availability monitoring in recent months. Please visit the NRT availability monitoring webpages for further information.
  • NRT quality monitoring for MetOp-C instruments - May 23, 2019
    Near-real-time data quality monitoring pages have been updated to include monitoring of MetOp-C AMSU-A, MHS and IASI, from ECMWF. Please visit the NRT quality monitoring webpage to access monitoring plots from these instruments.
