Abstract
Some results of lidar sensing of the ozonosphere in February and March of 1996 - 1999 at the Siberian Lidar Station (SLS) in Tomsk (56.5 degrees North, 85.0 degrees East) are presented. Observations shown that higher ozone contents in 1996 and 1998 were accompanied by a temperature rise in the middle stratosphere. High correlation between the vertical distribution and the total content of ozone in the lower stratosphere was found. The correlation analysis of vertical distributions of ozone and temperature revealed a significant positive correlation in the layer from 18 to 25 km as well as a significant negative correlation in the layer near 13 km. Altitude trends in the ozone content and the temperature in the stratosphere indicates a marked decrease of ozone and cooling of the atmosphere at altitudes of 22 - 30 km as well as an increase in the ozone content in the lower stratosphere, at the heights from 14 to 16 km. Trends in the NO2 content in 5-km layers in the stratosphere also indicate a statistically significant decrease in the NO2 content within the layer from 30 to 35 km.
