Abstract

Diurnal variation of the effective height of the aerosol layer H_V in the region of Tomsk was investigated. The effective height was determined as the ratio H_V =V_τ / V_ε of the volume concentrations of aerosol particles in the atmospheric column V_τ and in the near-surface layer V_ε. The volume concentration of the aerosol was determined by inverting the characteristics of the spectral transmission of light in the atmospheric column and on the horizontal path. The variability of H_V was compared for the submicron and coarse particle fractions. It is shown that the effective height is minimal in the morning and is amounts to 0.20–0.21 km for both fractions of aerosol. By the evening, the ratio H_V increases to 1.43 km and 0.875 km for submicron and coarse aerosols, respectively.
