The air pollution modelling system used in Tartu (population 101,000) is aimed at examining the pollution levels in different meteorological conditions, and determining optimal traffic schemes and strategic development plans for the city. The system consists of: (i) a Gaussian plume model AEROPOL, and (ii) a database on sources of NOx, CO, SO2 and particulates (from industrial, traffic, and domestic heating sources). The calculations of annual average and maximum concentrations are performed and fair agreement with monitoring results is found. A similar scheme is used in Parnu (population 60,000) and Kuressaare (population 15,000).
