研究期間：10108~10207;The physical and chemical processes of formation, emission, transport and transformation of atmospheric pollutants including acid substances, Asian dust, biomass burning and atmospheric mercury in Asian region are very complicated, resulting in impact on regional environment and climate. Taiwan is also influenced by such impact in direct and indirect ways. Therefore, this proposed study Phase IV (2012/8-2015/7) will continue legacy of the Phases I (2003/8-2006/7), II (2006/8-2009/7) and III (2009/8-2012/7), and to integrate ground-based measurements, remote sensing observation, climatic dynamic analysis, and model simulation in order to analyze the physiochemical processes during the long-range transport of above atmospheric pollutants, and further to assess their impact on regional climate. Besides, we will collaborate with USA Navy and NASA’s 7-SEAS (7 South East Asian Studies) for investigating the impact of biomass burning of Southeast Asia in order to study the impact of atmospheric pollutants and biomass burning of the South Asia. We have been conducting the 7SEAS’ pre-studies: 2010 Dognsh Experiment and 2011-2012 Son La Campaigns in northern Vietnam, for identifying the characteristics of biomass burning aerosol and pollution over source and receptor regions. Meanwhile, a special issue of Atmospheric Environment will include the results of 2010 Dongsha Experiment.
