Abstract
A comparison of the measured spectral aerosol extinction coefficients βa(λ) and scattering coefficients directed βS(θ). Coefficients βa(λ) were obtained from measurements of atmospheric transmission on horizontal path length of 1 km for wavelengths from 0.45 to 3.9 microns. Scattering coefficients βS (θ) were measured in the angular range from 1 to 15 ° at a wavelength of 0.53 μm. The data were obtained under conditions of forest fire smokes in July 2012 and in clean conditions in April 2013 (706 and 204 realizations, respectively). Under clean conditions, 82% of variations of the extinction of radiation in the whole wavelength range are caused by variability of coarse aerosol, and 98% of variations under smoke conditions are related to submicrometer particles.
