| Abstract: | The analysis of time series of the Linke turbidity factors is performed for the atmosphere mass m = 2 (T
2) and atmospheric aerosol optical thickness for the wavelength λ0 = 0.55 μm (AOT) from the data of 14 actinometrical stations of Central Siberia and Trans-Baikal territory. It is shown that
over the period from 1976 to 2006, the increased atmospheric transparency is observed in the region. Quantitative estimates
of changes in multiyear mean annual variations of T
2 and AOT at different periods of averaging and for different time periods are derived. |
