Peak concentrations of ground-level ozone during the summer heat waves of 2010 and 2016 in the background region of the Kirov region of the Russian Federation

Abstract

The analysis of continuous monitoring data on surface ozone concentrations during summer heat waves in July and August 2010 and 2016 in a low-urbanized region of European Russia, Kirov region 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.
