Abstract

Models of estimation of average and maximum concentrations of chemically active impurities in cross sections of plumes from remote stationary sources are suggested. Approbation of the models is carried out on data of aircraft sounding of multicomponent pollution of the winter atmosphere of the Norilsk industrial region. Process of active transition gas ® particle, observed at a distance of 58-103 km from a source of emissions, is numerically studied. Average and maximum sulfur oxidation rates in the winter polar atmosphere are estimated as 0.027-0.034 h-1 and 0.055-0.07 h-1, respectively.
