Determination of the gas composition from satellite measurements of the thermal radiation of the atmosphere
A.S. Garkusha

On the basis of calculations of outgoing thermal radiation of the atmosphere was studied the opportunities of determination the gas composition of the atmosphere by the measurements of IR Fourier-interferometer IRFS-2. On the basis of line-by-line calculations of the operators for direct problem and error matrix of optimal estimation method was investigated the possibilities of determination the total column amounts such gases  as CO2, O3, CH4, HNO3, N2O, CH3OH, HCFC-22, CFC-11, CFC-12 , PAN, and CCl4. Operators for the method of multiple linear regression was constructed and artificial neural network was trained to determine the total column amounts of the following gases: O3, N2O, CH4, HNO3, HCFC-22, CFC-11, CFC-12 and CCl4. The errors of these methods was evaluated.
