Title: Validation of a Radiative Transfer Model with Radiosonde and Satellite Data

The ARTS, Atmospheric Radiative Transfer System, is a new radiative transfer model developed by the SAT research group at IUP. It can be used for simulating any millimeter and sub-millimeter instrument for clear sky cases. AMSU-B is a passive microwave radiometer mounted on NOAA-15 and NOAA-16 satellites. Its purpose is to obtain data on global humidity profile of atmosphere.

In this study, to validate the model the simulated brightness temperatures were compared to AMSU-B brightness temperatures. The model simulations were based on radiosonde measurements from the DWD reference station at Lindenberg. The comparison was made for AMSU-B data from the satellites NOAA-15 and NOAA-16. The time period of the comparison is the whole year 2001.

The process of finding co-located matches in time and space, filtering mismatches and the results will be discussed during the talk.
