Abstract

The results of the experimental study of the spatial-temporal variability of the counting concentration of the highly dispersed (VDA) and submicron fraction (SMA) of aerosol in the atmosphere of the Baikal region are presented. A comparative analysis of the features of the distribution of the aerosol dispersion composition at the continental and coastal stations and during route measurements in the water area of Lake Baikal is carried out. The diurnal variations of the counting concentration of the highly dispersed (VDA) and submicron fraction (SMA) of aerosol have common patterns: the maximum diurnal concentrations are more often manifested in the morning, afternoon and evening hours. The general feature of the diurnal variations of the counting concentration of VDA and SMA is an increase in the concentration in the afternoon and evening hours. The average concentrations of VDA and SMA during of all period of measurements are equal: for suburban station of Ulan-Ude 4120 and 122 particles/cm³, respectively; for station “Boyarsky” 2646 particles/cm³, 43 particles/cm³; for water area of Lake Baikal 3055 particles/cm³ and 98 particles/cm³.
