Abstract
The paper presents the results of lidar measurements of the vertical ozone distribution in the lower stratosphere - upper troposphere at the Siberian Lidar Station (SLS) 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 and the increased ozone content in the lower stratosphere - upper troposphere recorded in March 2023 are shown. It is assumed that the event of high ozone content in the lower stratosphere - upper troposphere on March 9 was caused by a rather rare process of stratospheric - tropospheric transfer of an air mass through the tropopause.
