Experimental measurements of the aerosol optical depth of atmosphere on the southeast coast of Lake Baikal

Аннотация

Based on long-term measurements of the aerosol optical depth of the Baikal region atmosphere (Tory station and the Boyarsky station), the optical characteristics of the atmospheric aerosol are analyzed. The research results showed that the annual variation of the atmosphere spectral transparency in the Baikal region is mainly formed under the influence of natural sources of aerosols. It was revealed that in the long-term course of average monthly AOD values of the st. Tory atmosphere for 2012-2019 the spring maximum decreased, while the summer maximum increased, because the frequency and duration of forest fires increased during the summer months.
