Abstract

The paper describes the use of Geographical Information Systems in the framework of the realization of regional air quality management plans. The criteria for represented area, point and line emissions sources are briefly resumed. Particular emphasis is place on methodology for spatial distribution of area emissions on 1 km x 1 km grid, particularly on the use of the official EC cartography related to land use. For area emissions, the municipal level seems to be the most reliable defined to estimate emissions. Inside the municipality a square grid mesh is built-up to evaluate emissions for the application of diffusion models. To disaggregate pollutant emissions from the municipal level to the mesh level, the methodology of proxy variables is used. When the emissions which has to be distributed depends on an extensi
