Abstract:

We consider specific features in the spatial distribution and seasonal variations of the atmospheric aerosol optical depth (AOD) in a wavelength region of 0.55 μm on the territory of Povolzhye, Urals, and Western Siberia according to many-year data of satellite (MODIS/TERRA and AQUA) observations. The satellite values of AOD for particular regions of the Middle Urals are compared with AERONET observations in the region of Kourovka Astronomical Observatory. It is shown that the annual AOD variations from April to December are similar in all regions: with turbidity maxima, observed in spring and summer (August), and with minima in June and fall. On the average, the AOD values are larger in the south of the Western Siberia and Povolzhye and minimal in the Northern Urals. A high interrelation in the monthly AOD variations between individual regions is noted.
