Abstract
Major aspects of the physical and chemical transformations of sulfate and nitrate polluted air in central Japan are evaluated. The observed pollutant fields show that elevated SO
4
2− and NO
3
− concentrations occur in the central mountainous region of Japan in the late afternoon and early evening. Diagnostic analysis of one such episode, which occurred on 28 and 29 July 1983 using the STEM-II transport/chemistry model (Carmichael
et al., Atmospheric Environment, 1986) shows that these elevated SO
4
2− and NO
3
− levels are caused by precursors emitted in the Tokyo metropolitan area and subsequently transported ~150 km inland by an extended sea breeze circulation pattern. Predictions of SO
2, SO
4
2−, HNO
3, aerosol NO
3
− and PAN are presented and discussed. Nitrate is shown to be transported inland as HNO
3 during the day and then the equilibrium shifts to the aerosol phase as the polluted air mass is transported into the mountainous region in the late afternoon and early evening.
