Relatively high O3 concentrations were observed during an episode on July 16 and 17, 1981 in the Tokyo Metropolitan Area. The stagnant meteorological conditions which existed then were mainly caused by the local sea and land wind circulation systems. To better understand the physical and chemical relationships at work during this particular episode the SAI Urban Airshed Model (UAM) was applied. Vertical cross-sections of simulated pollutant patterns are analyzed for the Tokyo domain, including the diurnal variation in the patterns. The effects of vertical meteorological conditions and the previous day's secondary pollutants are emphasized. The entrainment of O3 and CARB from aloft on the second day of simulation was shown to have significant impact on the timing and location of the second day's maximum O3. Limited field-observed data from aircraft for O3 are compared with the simulated results.
