Minutes of the July 21, 2008 Meeting
Smoky Mountain AMS Chapter
A few people met first for dinner at Calhoun's on the River in Knoxville, and then around 20 people convened for the meeting in the Plant Biotech Building on the University of Tennessee Ag campus. Our speaker was Dr. Joshua Fu (Assistant Professor in the Department of Civil and Environmental Engineering at the University of Tennessee) who spoke about a very timely topic: "Air Quality during the 2008 Beijing Olympic Games".
The following was an abstract of his talk: "China is taking major steps to improve Beijing’s air quality for the 2008 Olympic Games. However, concentrations of fine particulate matter and ozone in Beijing often exceed healthful levels in the summertime. Based on the US EPA’s Models-3/CMAQ model simulation over the Beijing region, we estimate that about 34% of PM2.5 on average and 35–60% of ozone during high ozone episodes at the Olympic Stadium site can be attributed to sources outside Beijing. Neighboring Hebei and Shandong Provinces and the Tianjin Municipality all exert significant influence on Beijing’s air quality. During sustained wind flow from the south, Hebei Province can contribute 50–70% of Beijing’s PM2.5 concentrations and 20–30% of ozone. Controlling only local sources in Beijing will not be sufficient to attain the air quality goal set for the Beijing Olympics. There is an urgent need for regional air quality management studies and new emission control strategies to ensure that the air quality goals for 2008 are met."

Dr. Fu is an Assistant Professor in the Department of Civil and Environmental Engineering at the University of Tennessee. The focus of his research work includes ozone and PM emission and AQ modeling in State of TN, US and Asia by using Models-3/CMAQ and CAMx; development of real-time mobile source emissions for AQ models, international air quality modeling assessment; global climate change with the effects of air quality; development of cost-effective control strategies and alternative standards for managing tropospheric ozone and particulate matter; development of environmental decision support system on identification and demonstration of large-scale environmental management and policies; information technology research on the applications of a large-scale global climate and air quality modeling assessment.
