Abstract

The results of experimental studies of the daily variability of surface ozone concentration (O₃) in the atmosphere of the arid territory of Mongolia, obtained during scientific expeditions for the period 2005-2014 at the Sainshand station, are presented. Variations of hourly average concentrations of the O₃ changed from 70 to 126 μg m^-3.The daily variation of surface ozone concentration has minimal values in the morning during sunrise, and then there is an increase in ozone concentration in the daytime. The average amplitude of diurnal variations of O₃ was 56 μg m^-3.The maximum values of O₃ in the daily dynamic were observed in 2014, and the minimum values in 2007.The factors leading to increased surface ozone content and their relationship to meteorological and turbulent characteristics of the atmosphere are analyzed. A special mode of behavior of surface ozone, characterized by its day and night increase in daily changes, was revealed.
