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.
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.
The NWP SAF DBNet monitoring has 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 service. The FY-3D component is currently in trial dissemination mode, and the NWP SAF plots help to assure the quality of the data.
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.
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.
We have fixed the issue with software downloads.
Many parts of the NWP SAF website is back up and running but we are still working on the Software Downloads area which is not functioning.
If you do come across any other missing links or strange behaviour please let us know via the helpdesk.
Thank you for your patience during this period.
The NWP SAF website suffered a serious issue early on 8th May that resulted in an outage. Although the website is now available again, we are still working to restore the full content and functionality. We apologise for the inconvenience to users and thank you for your patience while we work to restore full service. Please continue to report issues through the helpdesk as usual. We will update you when everything is back to normal.
AAPP update 8.4 has been released. The changes include: (i) updates for Metop-C and FY-3D; (ii) a tool to process CrIS from SDR to BUFR, including VIIRS cloud mask and the cluster analysis that was introduced in AAPP v8.3; (iii) corrections to BUFR encode/decode; (iv) portability updates. The software has been tested on both RHEL6 and RHEL7 (equivalent to CentOS6 and CentOS7).
Version 2.4 of the Cloud and Aerosol Detection Software (CADS) is released. The software update introduces two significant developments. Firstly, processing capability is added for Chinese hyperspectral infrared sounders (HIRAS and GIIRS). Secondly, flagging of contaminated data in the presence of aerosol is made channel-dependent. For details, please see the CADS web page.
