Paper Abstract

The problem of mean statistic variability of the state of the aerosol component is considered in the paper on the basis of the data of spectral measurements of the aerosol optical thickness (AOT) obtained in Tomsk in 2000-2002. The characteristic variations of the atmospheric haze particle size spectrum at the increase of the atmospheric turbidity is considered on the basis of inverting the spectral data. The estimates show that, in average, the increase of the atmospheric turbidity is caused by growth of the content of the accumulative fraction. Formation of the well-pronounced mode of intermediately dispersed particles is characteristic of the states of the atmosphere with enhanced turbidity. Analysis of histograms of the distribution density N(τε) of the spectral values τ(λi) on the interval of the annual variability in 2000-2002 has shown that, in spite of the noticeable inter-annual differences in the statistical distribution of the values of AOT, all histograms of the repetition index have well-pronounced maximum and stable range of the most probable values (MPV).
