Positive Trend of Surface Ozone in the North of the Privolzhskii Federal Region of the Russian Federation

详细

The results of long-term continuous measurements of surface ozone concentrations, performed in 2010–2016 in the relatively low-urbanized region in the north of the Privolzhskii Federal Region of the Russian Federation (Vyatskie Polyany, Kirov oblast) are presented. A regular increase in the amplitude of diurnal variations of yearly average surface ozone concentrations is detected. The possible causes of this phenomenon can be both an increase in the atmospheric concentration of pollutants, i.e., precursors of tropospheric ozone, and climatic changes.
