Air quality is one of the main priorities for the improvement of the life quality in urban regions, as air pollution is usually, concentrated in such densely populated areas. Most of the countries have a national air quality monitoring network that allow an analysis of the air quality status, especially for urban regions that are nodes in this network. As the network is geographically distributed, it can be mapped in a natural way on an intelligent agents based system. The paper describes the modeling framework of an air quality monitoring and analysis multiagent system for urban regions.
