| Summary: | Reconstruction of the atmosphere composition vertical profile by emitted radiation intensity measurements V. S. ANTYUFEEV Abstract — We consider the method of reconstructing the concentration of species and gases in the atmosphere by the measured values of intensity of radiation emitted and absorbed in various radiation frequency bands. At the first step, we reconstruct the altitude profile of the total absorption factor for different observation frequencies. At the second step, we reconstruct the components concentrations at differ-ent altitudes. The inverse problem is ill-posed, statistical regularization is used for its solution. The reconstruction method proposed is compared to the standard one. The discharge of extremely active chemical species results in a severe environmental pollution, including the Earth atmosphere. The chemical reactions involving some chlorine compounds destroy molecules in a thin ozone layer in the upper atmo-sphere, which protects life on earth against a cosmic ray flux. These reactions are possibly involved in the formation of the so-called ‘ozone hole ’ over the Antarctic Regions. In this connection the monitoring of the upper atmosphere of the Earth by man-made satellites is needed. The processing of these observation results allows one to assess the trends for a change in concentration of species which destroy the ozone layer, neutral species, the amount of ozone in the upper atmosphere, where it is concentrated. Numerous research teams are now working on these problems all over the world. The launch of a man-made Earth satellite and its scientific equipment are an ex-pensive undertakings. In this connection four countries, viz. France, Finland, Swe-den, and Canada joined forces in order to launch the ‘ODIN ’ satellite from the |
