Simulation of Sulphur Dioxide Mass-Flow Over Milan Area

The evaluation of the air pollution impact on a large urban area from industries partially or totally surrounding it, is a cause for concern in many European cities. The problem is particularly important in Milan, a city with about 2 million inhabitants and an area of about 190 km2, located at the centre of the Po Valley in an industrial region. The continental climate characterized by frequent and prolonged temperature inversions, much fog during the winter and winds scarcely exceeding 2 m. s-1, leads to pollution build-up.
