“…Previously, it was shown that the pollution of the surface atmosphere with suspended solid particles up to 2.5 μm in size (PM2.5) across the territory of Krasnoyarsk occurs unevenly [7,10]. These studies did not assess the concentration of PM2.5 in the air of the ice-free Yenisei River.…”

PM2.5 particulate matter concentrations were measured at five monitoring posts along the Yenisei River over an area of about 18 km using certified CityAir stations. It has been established that in winter, the average daily concentrations of PM2.5 at these posts change almost the same way. Correlation coefficients are in the range of 0.75-0.96. High concentrations of PM2.5 are due to long periods of adverse meteorological conditions. It is shown that in the surface atmosphere above the Yenisei River, there is an uneven distribution of PM2.5 concentrations.

“…The most polluted cities include Krasnoyarsk. It is possible to assess the impact of various types of emission sources on the formation of unfavorable conditions by use of modern calculation models for the transport of impurities in the atmosphere, analysis of ground and satellite measurements and data re-analysis [4][5][6][7][8].…”

Atmospheric pollution is associated with weather conditions. Meteorological processes make a significant contribution to the creation of unfavorable meteorological conditions (NMU). NMUs are a special shortterm combination of meteorological factors contributing to the accumulation of pollutants in the surface layer of atmospheric air. We draw a particular attention to the temperature stratification of the lower layers of the atmosphere which can cause a temperature inversion – an increase in air temperature with altitude. Temperature inversion limits the vertical dispersion of harmful impurities in the atmosphere. Observational data show that the increased level of air pollution in the city of Krasnoyarsk is most pronounced in winter with temperature inversion and weak winds (no more than 1-2 m/s). To predict periods of increased concentration of pollutants in the boundary layer of the Krasnoyarsk atmosphere we consider a numerical algorithm for determining the time intervals of formation and destruction of temperature inversion based on a onedimensional vertical model.
