A new extra-large set of diverse atmospheric profiles has recently been compiled by the NWP SAF and is now available to the scientific community for the first time in nearly 10 years. Comprised of a year of ECMWF Copernicus Atmospheric Monitoring Service (CAMS) forecast data on 137 levels, the profiles represent one of the most up-to-date estimates of the vertical structure of several significant meteorological variables, atmospheric gases, and aerosols. Each subset of 5000 thermodynamically consistent profiles is meticulously selected to form a microcosm of the full model, optimised for 20 important atmospheric variables. The dataset can be used to train or validate a variety of model applications. RadSim v4 – to be released soon – will be able to ingest this new dataset, supporting clear-sky, aerosol, and hydrometeor RTTOV simulations with these new profiles.
