Abstract:

Aerosol turbidity of the atmosphere over Antarctica is the lowest on the planet. However, it shows regional peculiarities in the temporal variability. In this paper, the main features of the interannual and seasonal variations in the aerosol optical depth (AOD) are revealed on the basis of the analysis of its long-term measurements at Mirny Station. Pronounced variations with a period of 5–6 years and amplitude of 0.005 relative to the average level of 0.023 in the interannual variability of AOD (0,5 mm) are shown. The annual variation in AOD of fine aerosol is characterized by spring and summer maxima (October and February), and that of coarse aerosol is characterized by one summer maximum. Approximation formulas are proposed that make it possible to estimate the monthly average values of spectral AOD in the wavelength range 0.34–2.14 μm.
