Lidar and Spectrophotometric Measurements of Vertical Distributions of Ozone, Nitrogen Dioxide, and Temperature in the Stratosphere over Tomsk (Western Siberia)

摘要

At present lidar and spectrophotometric measurements of stratospheric ozone, nitrogen dioxide, and temperature at the Siberian Lidar Station (SLS) in Tomsk are used to study dominating atmospheric processes determining the variability of the vertical distribution and total content of ozone. The results of integrated measurements and synoptical analysis show that a good positive correlation between temperature and ozone and a variable correlation between ozone and nitrogen dioxide in the lower and middle stratosphere are observed for synoptical periods with strong dynamic activity of the stratospheric circulation processes. Sufficiently good negative correlation between ozone and nitrogen dioxide is observed in the periods with homogeneous stable circulation and weak dynamic activity. A better negative correlation between ozone and nitrogen dioxide in winter-spring may be observed for a seasonal change of the stratospheric circulation transfer.
