Investigation of the aerosol component of the optical density of the atmosphere under high mountain conditions

The data acquisition and processing system of the LGU atmospheric observation station on Mt. Shatdzhatmas near Mt. Elbrus is described. Particular attention is given to the study of a problem of atmospheric optics at this station: the variability of the aerosol component of the total spectral optical density of the atmosphere. A method for separating the residual optical density of the atmosphere in the absorption band into components is presented.
