Statistical Characteristics of Surface Ozone Concentration in Three Points of Tbilisi in 2017-2018

Eliso N. Kekenadze

Abstract


The statistical characteristics of surface ozone concentration (SOC) in three points of Tbilisi city (A. Kazbegi av., A. Tzereteli av. and Varketili) in 2017-2018 are represented. The data of National Environmental Agency of Georgia about the eight hour values of SOC are used.

 In particular, it is obtained that the greatest average annual values of SOC in Varketili were observed (53.9 μg/m³, the range of the change:  1-134 μg/m³), smallest – at the A.  Tzereteli av. (21.6 μg/m³, the range of the change:  0-102 μg/m³).  The value of the correlation coefficient between the eight hour values SOC between the points sufficiently high and changes from 0.74 to 0.91. 

The correspondence of values of SOC at the indicated points of Tbilisi city to the standards of WHO is examined.
