Abstract

The aerosol extinction coefficients in the wavelength range from 0.45 to 3.9 μm measured on a long horizontal path are compared with optical parameters measured in the visible wavelength range in a local air volume. The following parameters were analyzed: “dry” and “wet” angular scattering coefficients at an angle of 45°, as well as the mass concentration of the absorbing substance (“soot”) in aerosol particles. Round-the-clock measurements were carried out from March till November in 2000-2006. The comparison was carried out for three seasons: spring, summer, fall and four types of aerosol weather: “, background”, “haze”, “smog” and “smoke haze”. The role of each factor in extinction of optical radiation at different wavelengths is revealed.
