Abstract

In previous work, an integrated modelling system was developed, in order to analyze the urban NO* and NO; concentrations, and this model was successfully tested against the data from an urban measurement network. This paper discusses the extension of the modelling system in order to evaluate urban particulate matter concentrations. The model includes a treatment of traffic-originated pollution, pollution from stationary sources, regional and long-range transported background concentrations and resuspension of particles from street surfaces. The modelling system is based on urban dispersion models and a semi- empirical model, which utilizes data from the air quality monitoring network of
