The paper presents the results of expedition investigation of diurnal dynamics of ozone, nitrogen oxides, sulfur dioxide at different altitudes. The measurements were carried out to the south-east of Lake Baikal using a 30-m meteorological mast. Analysis of influence of thermal stratification on ozone content and other trace gases in a breeze circulation near the coastal zone is presented. Features of the altitude distribution of ozone and trace gases are revealed. Important role of breeze circulations in diurnal variations of ozone are noted, which influence transport and distribution of atmospheric impurities in Baikal region.
