The paper presents the results of solving the problem on choosing the set of spectral measurements channels capable of providing minimum errors in restoration of temperature from the data of sensing the upper atmospheric layers in the 15μm absorption band of CO2. The approach to solving the inverse problem allows one, in addition to temperature data, to extract the information on the profile of CO2 mixture ratio and on the probability of scattered photons survival. It is shown that using modern cooled detectors of radiation one can determine the atmospheric temperature up to 100 km with the accuracy of 1°K.
