Abstract

A comparative analysis of the seasonal mean diurnal behavior of aerosol characteristics was carried out using the monitoring data in the suburban area of Tomsk and in the background region in 2013-2019. It is revealed that the greatest contribution of anthropogenic sources to the diurnal variation of the concentrations of submicron aerosol and soot is observed in winter during their evening maximum at 8–9 p.m. The minimum urban load on these aerosol characteristics was detected in summer at 1–2 p.m. During the evening maximum of the aerosol and soot concentrations, a decrease in the parameter of condensation activity is observed in Tomsk compared to the background region.
