Abstract

The relationships between the aerosol extinction coefficients in the wavelength range from 0.45 to 3.9 micron, measured on a long horizontal path, and the angular light-scattering coefficients at an angle of 45°, are studied taking into account the mass concentration of the absorbing substance in aerosol particles obtained in a local volume. The role of air humidity in the change in the spectral structure of the components of aerosol extinction of radiation associated with the variability of submicron and coarse aerosols is revealed. The research was carried out within the framework of the state assignment of IAO SB RAS.
