Abstract
The relevance of studying the dynamics of ozone concentration is due to the fact that at high concentrations it is a potent poison and a powerful oxidizer that extremely negatively impacts both biological objects and the environment. Based on the monitoring data, the paper examines the distribution of tropospheric ozone in Russia in 2023 in the surface air layer, as well as its vertical distribution based on the results of aircraft sounding. It is shown that the maximum allowable daily average concentrations established by the domestic hygienic standard, maximum single, daily average, and annual average, were exceeded at all measurement points. The current situation necessitates widespread public awareness of the results of monitoring and the development of environmental measures to reduce the concentration of ozone and its precursors in the surface air layer.
