Abstract

Based on multiyear sun photometer measurements in the region of Tomsk, we discuss the specific features of seasonal and interannual variations in the finely and coarsely dispersed components of aerosol optical depth (AOD) of the atmosphere. The average spectral dependences and characteristics of AOD in characteristic (for annual behavior) months of the year, i.e., February, April, July, and October, are presented. The absence of statistically significant trend in multiyear AOD variations is noted. The annually average value is 0.04 for coarsely dispersed AOD component, and 0.12 for finely dispersed component (without accounting for the anomalous value 0.11 in 2012).
