Abstract
Ozone in the surface air layer in high concentrations is a powerful oxidizer that has a negative impact on biological objects and environmental elements. Therefore, it is very important to study the dynamics of its concentration in all regions of the planet. In the work, based on annual monitoring data, ozone concentrations in Russia in 2024, mesoscale differences in its content in individual regions, and its vertical distribution according to aircraft sounding data are considered; the comparison with hygienic standards is made. It is shown that the average annual ozone content in the surface air layer across Russia varied from 17 to 92 mg/m3; maximum hourly concentrations, from 90 to 222 mg/m3. In the annual course, the maximum concentration is usually observed in spring under background conditions and in summer in urban areas. A secondary maximum became noticeable at background stations in early autumn. The magnitude of mesoscale differences in concentrations reaches 50-70 mg/m3 and changes significantly during the day and year. In most measurement points, the maximum permissible daily average concentrations established by the domestic hygienic standard were exceeded: maximum one-time, daily average, and annual average. The current situation necessitates wide public awareness of the monitoring results and the development of environmental protection measures to reduce the level of ozone and its precursors concentration in the ground layer of air.
