SENSITIVITY OF THE URBAN AIRSHED MODEL TO OZONE PRECURSOR VEHICULAR EMISSIONS. VOLUME I: SENSITIVITY ANALYSIS FOR A SPECIFIC GEOGRAPHICAL LOCATION
In this study, the Urban Airshed Model (UAM) is applied to investigate the relationship between ozone concentrations and mobile source emissions, with the goal of helping transportation professionals to understand the application of the UAM and how it can improve the integration of transportation and air quality planning. This report first discusses the chemical background of ozone pollution and its relationship to vehicle emissions. Then the UAM model is described, as well as the methodologies applied in this project. Further, the sensitivity of ozone concentration to the changes in vehicle emissions is evaluated. It was found that under the conditions specified in this project, ozone concentration is more sensitive to the changes of nitrogen dioxide, rather than Volatile Organic Compounds (VOC) in vehicle emissions. This finding indicates a nitrogen dioxide based ozone control program may be appropriate for the specific region under the study. The significance of the findings for future studies is also discussed.
