The paper presents the approach to isolation of the regular component of daily behavior of the aerosol optical depth and columnar water vapor of the atmosphere. The average diurnal dynamics of these parameters in Tomsk is compared with that in suburb background area, as well as in other regions: Yekaterinburg, Irkutsk, Yakutsk, Ussurijsk. General features of the dynamics are observed in the regions of Tomsk, Yekaterinburg, and Irkutsk. Some individual peculiarities caused by local factors are characteristic of Yakutsk and Ussurijsk. The parameters of approximation of the average diurnal behavior of AOD of the atmosphere are presented for Tomsk, Yekaterinburg, and Irkutsk.
