Abstract:

The results of lidar observations obtained at the Institute of Atmospheric Optics SB RAS, Tomsk, in January-March, 1996-2000 are presented. The data on the presence of water in mesosphere and upper stratosphere are discussed. The influence of geophysical processes on aerosol layer formation is considered. The correlation between aerosol layer formation in the upper stratosphere and anomalous winter absorption of radio waves in the lower ionosphere is considered. It is shown that the conditions for water condensation and water aerosol formation appear in periods of anomalous winter absorption of radio waves in ionosphere above the stratopause, which can descend in these periods to altitudes of about 40 km.
