Abstract:
Houston has long been known to suffer from poor air quality, especially ground ozone level produced from photochemical reactions between nitrogen oxides (NOx) and Volatile Organic Compounds (VOC) in the presence of sunlight. In order to investigate impact of various emissions on air quality in Houston, combination of biogenic emissions with anthropogenic emissions were simulated for 2012 ozone episode. In this research, impact of on-road mobile source emissions on air quality in Houston were assessed. On-road mobile source inventories were developed using the EPA's MOVES (MOtor Vehicle Emission Simulator) model. Emissions Preprocessor System was used to convert the developed on-road mobile source inventories to suitable format. The converted on-road mobile source inventories were combined with biogenic emissions as the air quality model input. CAMx (Comprehensive Air quality Model with extensions) model was used to simulate various air pollutants concentrations for 2012 ozone episode. Simulation results showed that various transportation patterns have quite different influences on the air quality in this region.
