This paper describes the implemened information-computational system (ICS), oriented to the forecast of air quality over the area of the city and its suburbs. The concise description of the mathematical models, components of the ICS, the order of application execution, and visualization of calculation results are given. The qualitative coincidence of computed prognosis of concentrations of ozone, carbone oxide, and nitrous oxide with measurements of IAO SB RAS TOR-station is demonstrated.
