摘要：

We have developed a modelling system for evaluating the emissions, dispersion and chemical transformation of nitrogen oxides from traffic. This paper presents an application of the system for estimating the NO2 and NOx concentrations in the Helsinki metropolitan area in 1993. The highest concentrations of NO2 are located in the vicinity of the main roads and streets, and in the downtown area of Helsinki. The model predictions were compared with the results of the urban air quality measurement: network of the Helsinki Metropolitan Area Council. The predicted annual average concentrations and statistical concentration parameters of NO2 agree well with the measured data.
