Paper Abstract

The paper studies the changes in the gas composition of the atmosphere in the surface layer for the Tomsk region (Akademgorodok) during the periods of sharp change of air masses. Studies were conducted for the summer seasons (June-August 1993-2018) for the periods of change of air masses from warm to cold. Ozone, carbon dioxide, carbon monoxide and sulfur dioxide (O3, CO2, CO, SO2) concentrations were used for the analysis of the change in chemical composition. The concentrations have been derived from TOR station. For the analysis of air mass change, ECMWF Era-Interim data on the potential temperature on the dynamic tropopause (PV-θ) was used. The paper studies the processes air mass change in which the difference of PV-θ anomaly was about 20-30 K. It was found that the concentration of CO2 is mainly increasing, and concentrations of O3 and aerosol are decreasing during the polar intrusion. For CO and SO2, no dependence on a sharp change in the air mass properties was found.
