Vertical Distribution of Ozone in the Upper Troposphere–Stratosphere according to lidar Sounding Data at the Siberian Lidar Station in 2023

The paper analyzes lidar measurements of vertical ozone distribution in the lower stratosphere–upper troposphere at the Siberian Lidar Station of V.E. Zuev Institute of Atmospheric Optics, Siberian Branch, Russian Academy of Sciences, over Tomsk in 2023. The annual variation in the vertical ozone distribution is shown, as well as high ozone content in the lower stratosphere–upper troposphere recorded on March 9, 2023, which is assumed to be caused by a quire rare process of stratospheric–tropospheric air mass transport through the tropopause.
