Application the complex WRF/CAMx models to study the influence of adverse weather conditions on air quality in Tomsk city

Abstract

The influence of adverse weather conditions on air quality in Tomsk for certain dates in 2022 and 2023 was studied numerically using WRF and CAMx models. Calculated from hourly concentrations, the Common Air Quality Index is used to evaluate the level of air pollution. The numerical experiment was carried out on the implementation of measures to regulate emissions of business entities to improve the quality of atmospheric air in the city of Tomsk, depending on the declared regime of adverse weather conditions. It was found that in order to uniformly reduce the concentrations of the main pollutants of urban atmospheric air for the conditions under consideration, it is advisable to limit emissions from road traffic.
