“…Existing methods of atmospheric ozone recovery according to the measurements of modern IR probers show that in determining the total ozone content, accuracy of the order of 5-10% is achieved. The main difficulties and limitations of ozone detection based on the results of measurements of satellite IR probers are associated with the influence of variation in the temperature of the underlying surface and the vertical profile of the atmosphere, the presence of aerosol layers in the field of view of the radiometer and its spectral resolution of the recording of outgoing radiation of the Earth's [19][20][21][22] .…”

The report provides an analysis of the dependence of the ozone absorption coefficient on the change in temperature and pressure in the atmosphere in the spectral region of 1000-1070 cm-1. Two spectral sections of the outgoing radiation of the atmosphere (1002-1003 cm-1) and (1020 -1021 cm-1) of the ozone absorption band with the opposite dependence of the ozone absorption coefficient on the change in gas temperature were determined. The atmospheric model is presented in the form of homogeneous layers of 100 meters to an altitude of 40 km. The parameters of the layers are determined for the standard atmosphere and the contribution to the outgoing radiation of the atmosphere in the investigated spectral sections of the ozone absorption line 1002-1003 cm-1, 1020-1021cm-1 is equal to the contributions to the outgoing radiation of the Earth's surface and all the heterogeneous layers that make them up. A possible method of adjusting the temperature of the Earth's underlying surface and the ozone content is shown by the convergence of the results of simultaneous calculations of the amount of investigated gas in the atmosphere by the outgoing radiation in the investigated spectral areas.
