“…These minimal TOCs are most distinctly manifested for summer and fall periods (corresponding to the 150-300 counts in the year). It is noteworthy that the curve of decreasing TOC values in this interval resembles the decaying exponential dependence, pointed out by the authors in analysis of data, obtained using the IAO instrument in the period of 1994-2017 [5]. After average values (respectively, TOC IAO =359.6 DU, TOC IMCES =352.3 DU, and TOC OMI =342.1 DU) are subtracted from annual behaviors, presented in Figure 3а, and after smoothing over 11 points (this procedure removed the highfrequency variations), the TOC values came to closer visual correspondence (see Figure 3b).…”

We present the time series of the total ozone content (TOC) over Tomsk, obtained using three independent spectrophotometers, and carry out their comparative analysis. Comparison of measurements by these instruments shows that they well correlate in terms of the pronounced variations, arising in time behaviors; but the amplitudes of the bursts differ. On the whole, we can note that the TOC values, obtained using IAO instrument, exceed those from two other instruments, TOC values from NASA instrument being the lowest. These smallest TOC values are especially apparent for the summer and fall periods.

“…Some experiments in the field of stratospheric aerosol research include understanding the impact of stratospheric aerosols on climate and atmospheric dynamics, studying the composition and properties of polar stratospheric clouds, and tracking the dispersion of volcanic ash and other airborne particles. Many of these studies are focused on combining ground and airborne lidar measurements to achieve a better understanding of stratospheric aerosols and their behavior, as well as developing advanced data processing and analysis techniques to extract useful information from lidar data [7][8][9][10][11][12][13][14][15][16][17].…”

The possibilities of using broadband sources, as well as an additional wavelength of 630 nm in a lidar-balloon experiment on sensing stratospheric aerosol, are considered, a modification of the calculation procedures according to the Mie theory is carried out, taking into account the parallelization of calculations by wavelengths and particle radii using the tensorflow library, a visual and correlation analysis of the efficiency of using lidar wavelengths and broadband LED sources. The study was supported by the Russian Science Foundation grant No. 23-27-00057, https://rscf.ru/project/23-27-00057.

“…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.
