The paper considers the spatial-temporal distribution features and seasonal variability of atmospheric aerosol optical depth (AOD) in the spectral range of 0.55 μm in the Baikal region according to long-term data (2005–2019) of satellite observations (MODIS/Aqua). The satellite AOD values are compared with the AERONET observation results at the Geophysical Observatory of the Institute of Solar-Terrestrial Physics SB RAS. It is shown that the interannual variability of AOD is mainly due to the impact of forest fires and has the same character: the maximum atmospheric turbidity was observed in 2008, 2012, and 2014, and the minimum in 2010, 2013, and 2016. A decrease in AOD with an increase in latitude with a gradient of Δτ = 0.002…0.001 per degree of latitude is noted. The average seasonal AOT variations at six observation points are characterized by spring (April) and summer (July) maximums and low autumn AOD values. From June to November, the decline in average monthly AOD values is more than 60 %.
