Abstract

The results of 25-year measurements of the aerosol optical depth of the atmosphere (AOD) at Mirny observatory (Antarctica) are discussed. It is shown that the annual average AOD values in 1996 – 2020 are characterized by statistically significant oscillation with a period of 5 years. The AOT variability is compared with the Antarctic oscillation index and the frequency of occurrence of the three main types of atmospheric circulation in the South Polar Region.
