Abstract

Results are presented of the analyses of the 3D structure of the atmosphere with TOVS sounding data for two atmospheric situations over Europe. Both situations include the occurrence of thunderstorms. The retrieval methods used are the International TOVS Retrieval Package (ITPP-4) and the Improved Initialization Inversion (`3I-2') algorithm. These methods are applied to locally received real-time direct readout HRPT data. Both methods show meso scale phenomena in the temperature fields, represented by the thicknesses 500/1000. Radiosonde observations, as well as model analyses, do not show this phenomenon. The synoptic structure of the temperature field as well as the humidity field is comparable with all methods. Thus it can be concluded that there may be additional information in satellite derived atmospheric data, also on a scale at about meso-alpha/meso-beta. Statistics show that the structures of the fields are comparable at 98 - 99% correlation coefficient. This result can be improved by not using cloudy retrieval boxes. Collocations with radiosondes show a good agreement within the troposphere, thus a good simulation of stabilities can be expected by satellite data.
