Monitoring of ground-level ozone in the Karadagsky State Nature Reserve in 2024.

The time course of the surface ozone concentration in the KaradagskyStateNatureReservein2024 has been analyzed. Two maxima are observed in the seasonalcourse of ozoneconcentration: the main one inJuly–August,andtheweaker one inApril–May. A similarseasonal pattern of ozone concentration is typical for European Mediterranean stations. The average daily course of the PCO in winter is practically not pronounced. In summer, the maximum average hourly ozone concentrations were recorded in the direction of airmasses,relative to the location of the BEMS, from the sea. During 2024, there was an episode(on August19) of exceeding the maximum permissible maximum single concentration of ozone(160  ug/m³).

The work was performedwithin the framework of the topic of the State assignment(№ 124030100098– 0).
