By results of lidar observations carried out in 2007-2009 years in Kamchatka, the seasonal dynamics of
aerosol distributions in the range 30-80 km is analysed. Double layered structure of aerosol appearance, located
at 35-50 and 60-75 km was find out. The similarity and distinctions of aerosol distribution in Kamchatka with
the West Siberian ones was established. The method of correcting lidar signals, allowing to restore dispersion
ratio up to 80 km, is described.
