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.
