Changeability of Monthly Mean Values of Surface Ozone Concentration (SOC) in Three Points of Tbilisi from January 2017 to October 2021

The statistical characteristics of the surface ozone concentration (SOC) in three points of Tbilisi city (A. Kazbegi av., A. Tsereteli av. and Varketili) from January 2017 to October 2021 are represented. The data of National Environmental Agency of Georgia about the mean monthly values of SOC are used. In particular, it is obtained that the greatest average values of SOC during entire period of observations in Varketili were observed (68.0 mcg/m³), smallest - on A. Tsereteli av. (43.9 mcg/m³). The value of the linear correlation coefficient between the mean monthly values of SOC on all points changes from 0.88 to 0.96. The influence of limitation on the movement of public transport in Georgia in different time periods from March 2020 to August 2021 in connection with the pandemic of coronavirus COVID-19 to the changeability of the level of SOC is studied
