Abstract:

Data of many-year minutely measurements of the concentration of aerosol and gaseous pollutants in the near-ground layer have been analyzed to study the spatial structure of mesoscale inhomogeneities in the concentration within the lower troposphere. A periodic structure has been revealed in analyzing longitudinal correlation functions with a varying time lag. Excluding diurnal behavior has allowed us to separate significant peaks in the correlation functions of the concentrations that are most likely caused by transport from neighboring industrial centers. The mean speed of transport ranges from 1.2 to 1.4 m/s, and the mean wind speed exceeds it roughly by 15-20%.
