Abstract

Statistical characteristics of the variations of the spectral aerosol extinction coefficients α(λ) and meteorological parameters in near-ground atmospheric hazes are considered in this paper. To more adequately physically interpret the origin of variations, the total aerosol extinction coefficients are divided into components Δα₁, Δα₂ and Δα₃ caused, respectively, by submicron (radius r≈0.05 to 0.45 μm), intermediately dispersed (r≈0.5 to 1.5 μm) and coarse (r>1.5 μm) particles. The relation of these characteristics with meterological parameters of the atmosphere are analyzed, and the role of different factors determining the variability of the aerosol extinction in visible and IR wavelength ranges is assessed.
