Extreme Surface Ozone Concentrations in the Kirov Region of the Russian Federation during Summer Heat Waves of 2010 and 2016

The purpose of this work was a comparative analysis of the peak values of surface ozone content recorded at the Vyatskiye Polyany monitoring station during summer heat waves in July-August 2010 and 2016, when wavy and abnormally high air temperatures were observed for quite a long time. The analysis of the continuous monitoring data is presented. The values of the maximum short-term (peak) recorded values, obtained at 20-minute, 1-hour and 8-hour averaging, were analyzed. Under close temperature conditions, the amplitudes and durations of peak ozone concentrations in 2016 significantly exceeded the values observed in 2010. One of the possible reasons for this difference may be associated with an increase in the concentration of ozone precursors in the region’s atmosphere.
