Abstract

Was compared to the measured spectral aerosol extinction coefficients βa(λ) (λ: 0.5 - 3.9 μm) with coefficients directional light scattering βS(θ) (λ = 0.53 μm, θ: 1-45 °) and with mass concentration of the absorbing material in aerosol particles MBC. Measurements of optical and meteorological parameters were performed under conditions of forest fire smokes in July 2012 (706 realizations). It is shown that the magnitude of the aerosol attenuation of visible and infrared radiation can be estimated with certain accuracy, by measuring the light scattering parameters in a local volume. For dense fumes βa (0.55)< 1 km -1 was estimated single scattering albedo, which amounted to 97 - 98% in the visible region of the spectrum.
