Abstract
We have developed a modelling system for predicting the emissions,
dispersion and chemical transformation of nitrogen oxides in an urban area.
The system takes into account of all source categories, including stationary
point and area sources, and vehicular sources. This paper describes a
comparison of the predicted NO% and NOi concentrations with the results of an
urban air quality measurement network. The comparison included four
monitoring stations in the Helsinki metropolitan area in 1993. The predicted
and measured NOi concentrat
