Presented are the results of surface ozone monitoring in the atmosphere over Ulan-Ude during the period from 2000 to 2012. Revealed are seasonal and diurnal variations of surface ozone. The analysis of the seasonal variability of surface ozone concentration in di cates the presence of the clearly pronounced maximum in spring-summer period. A statistical model of forecasting single concentrations of the surface ozone is considered using the multiple regression analysis. Temperature, relative humidity, wind direction, wind speed, turbulence factor, temperature gradient, velocity of vertical flow, and concentrations of minor gas admixtures such as nitrogen oxides are used as predictors. Analyzed are statistical relationships, where observed ozone values are presented in the form of the regression function of the most significant predictors.
