Photochemical air pollution episodes during 15-20 July 1981, covering the Tokyo Metropolitan Area under the stagnant meteorological conditions, were analyzed. Three-dimensional (3-D) pollutant and meteorological observations showed that polluted air masses followed sea and land breeze circulation patterns. Aged secondary pollutants were detected aloft from midnight until early morning. These pollutants subsequently entrained into the daytime mixed layer and affected O3 formation. To understand this stagnating system, a simple trajectory model was used. Simulated results showed good qualitative agreement with observations, but the model overestimated the surface concentration and underestimated the aircraft observations. This was mainly caused by the assumption of vertical uniformity within the model.
