Simulation of atmospheric emission and retrieval method for atmospheric composition from high-resolution IR spectra of satellite interferometer

Some developments that are planned to be included into an information system for atmospheric applications are considered. A fast algorithm to retrieve temperature, pressure, and mixing ratio altitude profiles of the atmosphere composition from high-resolution spectra that are recorded by the interferometer of a new generation on the satellite platform is discussed. The algorithm is distinguished by the analytical computation of the derivatives, entered the inverse calculations, and by the regularization technique. Validating this code, the MITI's IMG data, recorded on board NASDA's ADEOS satellite, is used in order to retrieve a realistic temperature profile of the low atmosphere up to altitudes of 20 km.
