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/.
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.
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.
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.
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 different runs.
