Abstract:
Based on the long-term series of observations of the aerosol extinction of the atmosphere along a surface horizontal path near Tomsk, we analyze the interannual variability of the aerosol extinction coefficient be(l) in the spectral region from 0.44 to 3.91mm. The interannual stability of the most probable values is revealed. It is shown that the distribution of the frequency of occurrence for the aerosol extinction coefficient N(be) measured in the spectral region wavelength range from 0.44 to 3.91mm is close to lognormal. Specific features of the annual observation series manifest themselves mostly in the range of the increased values of the aerosol extinction coefficient. The most significant fluctuations of the spectral values of the aerosol extinction coefficient in the region under study are caused by smoke of forest fires. The interannual variation of the left branch of the dependence approximating distribution of the frequency of occurrence N(be) are caused by variations in the statistics of arctic air mass invasions into the region under study.
