Air pollution dispersion modelling activities

The Air Quality division has seven departments: *Air Quality Information System * Emission and Sources * Modelling and Expertise Pool *National Inventorization System *Air Quality Monitoring *Central Air Quality Laboratory *Calibration Laboratory The work of the Modelling and Expertise Pool department is focused upon: the development of air pollution dispersion models; the application of such models in the preparation of expert reports and opinions; forecasts of air quality control; the processing of operating information on pollutant concentrations obtained by the Airborne Monitoring section. The SYMOS97 air pollution dispersion model was developed at the CHMI. It models the dispersion of continuous, neutral or buoyant plumes from single or multiple point, area or line sources. It can handle complex terrain and it can also be used to simulate the dispersion of
