Major aspects of physical and chemical transformations of the polluted air mass resulting from high-precursor emission fluxes of NOx, SOx, and reactive hydrocarbons and their subsequent long-range transport were evaluated. The ammonium-nitrate-aerosol equilibrium formulation of Stelson et al. (1982a,b) and the Advanced Scavenging Module of Hales (1984) are incorporated into the two-dimensional Sulfate Transport Eulerian Model II of Carmichael et al (1986). Diagnostic-model analysis for a better understanding of the relationships between transport and chemistry of the polluted air mass under rather-complex flow situations were performed. This study was conducted in the Kanto District and the Nagano Prefecture in Japan in July, 1983, characterizing the impact of emissions from the Tokyo metropolitan complex on the air quality of an important resort and forest area in a mountainous region about 150 km away. Model results are in good agreement with observed data, and show that damage arising form a high O/sub 3/ concentration level can be reduced by reducing the NMHC sources around the Tokyo metropolitan complex.
