Results of measurements of ground level ozone concentration in an atmosphere of Ulan-Ude and at southern coast of Lake Baikal in October, 1998, in January, May, July, 1999 are given. Seasonal variations of ground level ozone concentration in Ulan-Ude are received for the first time. The high hourly average values of ozone in summer period are revealed. Formation and distribution of gas impurities in a coastal zone of Lake Baikal in summer period of observation is connected with photochemical and local circulating processes. The low values of ozone concentration are the reason of prevalence of processes of formation NO₂ above processes photolysis. High values of NO₂ concentration at southeast coast of Lake Baikal are caused by action of anthropogenous sources.
