Supplement to "On the accuracy of RTTOV-SCATT for radiative transfer at all-sky microwave and submillimeter frequencies"

This supplement contains a set of realistic cloudy and precipitating conditions from the Integrated Forecast System (IFS) of the European Centre for Medium-Range Weather Forecasts (ECMWF) and the corresponding simulated brightness temperatures for the journal article “On the accuracy of RTTOV-SCATT for radiative transfer at all-sky microwave and submillimeter frequencies”, which is under review at the Journal of Quantitative Spectroscopy and Radiative Transfer. These data are available as benchmark for model developers.

The IFS profiles correspond to model data interpolated (using the IFS observation operator) to the locations of the Atmospheric Infrared Sounder (AIRS) for a 12 h period centred on 03 UTC on 1 November 2018. Note that only a subset of the full set of AIRS locations are supplied here. The IFS model version cycle 46r1 was used, in a research experiment, to generate these profiles. The model was configured to T1279co resolution  (about 8-9 km) with 137 levels in the vertical. The forecast was initialized from operational analyses at 18 UTC on 31 October 2018, and hence corresponds to the 12 h forecast "background" used in the data assimilation cycle.

The following information concerns only the IFS model data:
