- Abstract
Presented are some results of sulfur dioxide measurements over South Baikal and Irkutsk Reservoir performed with the research vessel I.D. Papanin. It is obtained that sulfur dioxide concentration over the whole South Baikal did not exceed 1-2 μg/m at the absence of northwestern air mass transport in the region. On one of the days, two maxima of sulfur dioxide concentration were registered at the west-northwestern wind: over Irkutsk Reservoir (>80 μg/m) and over Lake Baikal, between Listvyanka and Bol'shie Koty settlements (>40 μg/m). It is supposed that the revealed maxima are the traces of sulfur dioxide plume from the sources in Irkutsk city. Numerical experiments with the mathematical model and the analysis of air mass trajectories corroborate this idea.
