Abstract
The results of the analysis of changes in the quality of atmospheric air in the city of Ufa from 2017 to 2020 are presented. The influence of meteorological factors on the level of pollution in the city of Ufa is considered. The basis for the analysis are instrumental measurements at nine Roshydromet stations. The daily values of the atmospheric pollution parameter are calculated. Trends in the level of atmospheric pollution by various impurities are determined. Using the method of wavelet transformation, the characteristic periods in the variations in the level of pollution are ascertained. Using the cross-wavelet analysis, links between air pollution and dangerous meteorological parameters are revealed. It is found that the average concentrations of sulfur dioxide, xylenes, and toluene increased in 2017-2020; high level of atmospheric pollution is observed in the calm weather, light winds, and temperature inversions. The observed changes in urban air pollution provide unique grounds for experimental assessment of the impact of various anthropogenic factors on the qualitative composition of atmospheric air.
