“…It is well known that the optical thickness of the atmosphere is an important parameter that characterizes the integral extinction of solar radiation as it passes through the atmosphere. As rightly stated in [6], large-scale studies of the physical properties of atmospheric aerosol should be carried out to address climate change issues. Trace amounts of gases in the atmosphere significantly affect the weakening of the optical radiation of the Sun.…”

“…In this regard, one of the important issues is the correct consideration of the effects of hydrometeorological factors on the optical properties of aerosol. It is shown in [6] that when studying the effect of moisture on the optical thickness of atmospheric aerosol, it is important to take into account the fact that water vapor affects the aerosol along the entire length of the vertical section of the atmosphere, as well as on the ground surface. Taking into account the indicated factor, the effect of all the accumulated column values of water vapor on the optical thickness of the aerosol should be studied.…”

“…Towards longer wavelengths of 750-940 nm, the hygroscopic growth factor once again starts to increase. The redistribution of the aerosol particle size distribution function is an expected outcome resulting from the hygroscopic growth of aerosols [6]. At the same time, it is unacceptable to analyze the statistical situation of aerosol pollution for the purpose of ecological monitoring of environmental pollution with gases and aerosols.…”

The emergence of strong desert vortices covering large areas, including the areas of large cities with dense population, the need to quickly obtain sufficient information on the state of desert ecosystems in large areas makes the application of remote sensing methods an urgent issue. At present, the method of measuring the desert aerosol using scattered solar radiation has been proposed, and the method of measuring the optical thickness of the dust aerosol has been substantiated. A new method of optimization of remote sensing systems and information-measurement systems in general is proposed in the article. A method of remote determination of aerosol optical thickness increase, which involves measuring the scattered radiation of the sun, has been proposed. The main goal of the study is to develop a remote sensing method that allows determining the dynamics and cause of the increase in aerosol optical thickness. The scientific novelty of the work is a new method that is invariant to the variations of the aerosol optical thickness under the influence of hydration and dehydration processes. By using the proposed three-wave biparametric Sun photometer, the effect of aerosol hygroscopic growth on the measurement results is eliminated.The given critical assessment of the state of atmospheric pollution monitoring and the consideration of the main shortcomings of the aerosol pollution monitoring carried out in the country will allow further improvement of such monitoring in the future. The proposed remote sensing method for determining the dynamics of aerosol optical thickness growth allows to determine the origin of aerosol optical thickness growth by measuring scattered solar radiation at two different wavelengths and in two optical air masses.
