RadSim v4.1 has been released. This has been updated to work with RTTOV v14.1. New features include: support for new RTTOV capabilities including MFASIS-NN aerosol simulations and new simulation options, option to specify a range of channels to simulate instead of an explicit channel list, and support for temporal interpolation between ECMWF GRIB fields at multiple analysis times (not only multiple forecast times). A full list of updates is here.

NRT availability monitoring update
The NRT coverage and timeliness monitoring has been extended to now also include data from the new MWS instrument on Metop SG A1 based on the data reception monitoring at DWD. The new data have been included in the status overviews: NRT availability status and plots for coverage as well as time series and PDF’s of data timeliness and geographical plots of data timeliness are accessible via the following link: NRT availability
Update to the Web Based Satellite Sounding Training Application
Improvements to the WeSS4T web application: https://sounding.trainhub.eumetsat.int/, has been deployed on the Eumetsat Training Hub, hosted by the EWC. The update increases traffic load capability and improves overall user navigation. The application is an excellent tool for training in radiative transfer and for introducing the basic concept of data assimilation. Feedback regarding the use of this application is encouraged and appreciated.
RTTOV v14.1 has been released
RTTOV v14.1 has been released.
Updates from v14.0 include: MFASIS-NN neural network fast solver for visible/near-IR scattering simulations improved to support additional VIS/NIR channels for cloudy simulations and now supports aerosol simulations with CAMS optical properties, new cloud overlap options have been implemented, new option to turn off cosmic microwave background radiation contribution (for use with obs that are processed to remove this), new option to exclude sun-glint from the solar sea reflectance model (for certain simulated imagery applications), optimisation of the SURFEM-Ocean microwave sea surface emissivity model for gfortran builds, optimisation of the DOM solar solver with Rayleigh multiple scattering, faster cloud simulations with maximum-random overlap due to elimination of redundant zero-width columns, and various other updates and improvements.
See the RTTOV pages for more information.
Migration of “DBNet monitoring” email alerts to generic sender
The DBNet monitoring data outage and data consistency email alerts had previously been sent from a personal Met Office email account. However, as this is a service run on behalf of EUMETSAT’s NWP SAF, it seems appropriate that a more generic email address is used as sender. Therefore, as of the 9th January, these email alerts are sent from the email address dbnet-monitoring@metoffice.gov.uk, with the Display Name “NWPSAF DBNet monitoring”.
