| Abstract | Photochemical smog model system, UAM-V/SAIMM was applied to gain an insight view of the formation and accumulation of the pollutants in the Hanoi Metropolitan Region domain. Horizontal grid of 4km x 4km was selected. The vertical structure of the SAIMM model consisted of 6 levels with the model top at over 5000m while the UAM-V model consisted of 6 layers with the top height of 50m, 100m, 500m, 1500m, 2500m, and 3500m Annual average gridded anthropogenic emission database including area sources and point sources were prepared for the model input. Emission factor were taken from a limited measurements available for the sources in Hanoi, US EPA AP-42 and other literature sources. Biogenic VOC emissions were determined based on land use pattern of Hanoi Metropolitan Region. Due to the lack of VOC emission profiles in Hanoi, the reported European VOC emission profiles were used in this study. 03 episode of March 3rd to 4th in 2003 was selected for simulation. Hourly surface boundary conditions were estimated from observed pollutant concentration in Hanoi while constant default values were used as upper layer lateral boundary conditions. For the episode selected, visual spatial and temporal comparisons between simulated results by two models and observations for 03 as well as statistical performance criteria evaluations of the models performance was conducted. The selected model system produced acceptable 03 predictions for the domain. However the monitoring data is still limited and not enough to produce a reasonable comparison with modeling output. This thesis provides some preliminary results. Hence, it is necessary to conduct follow-up researches for more accurate modeling results. |
