Abstract

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.
