Abstract

The research studies the unfavorable meteorological and synoptic situations contributing to an increase in the concentration of sulfur dioxide (SO₂) and carbon monoxide (CO) in the air basin of the Southern Baikal region. Atmospheric impurities and meteorological parameters were registered at the Listvyanka station with SV-320 and R310-A chemiluminescent gas analyzers, as well as a Meteo-2M ultrasonic weather station. General synoptic processes over the region were studied using the Digital Atmosphere software and the HYSPLIT trajectory model. The influence of various meteorological conditions on the atmospheric air over the Listvyanka station in 2020 and 2021 was determined.
