The shaping of urban agglomeration boosts the regional economy, and also aggravates the hazy pollution in atmosphere. Under the background of rapid urbanization and industrialization, as well as the influence of the air parcel transported and diffused from external area, the city group in the Western Coast of Taiwan Strait, China (abbreviated to CGWCTS), located in the alternant belt of sea and continent, recently has presented the evident trend of multiplex air pollution. The issue of hazy pollution in CGWCTS can not be neglected and eschewed. The project intends to choose CGWCTS as the studied area containing different kinds of environmental observation sites, and aims at studying the physical and chemical mechanisms for the formation and dissipation of atmospheric haze among CGWCTS by the integrated methods of field and satellite observation, laboratory experiment, air models, and the tracer of stable isotopes. The main contents in this research are: (1) the key chemical factors and meteorological condition affecting the formation and dissipation of atmospheric haze among CGWCTS in different seasons; (2) the distinct sources and proportions of pollutants inducing haze phenomena; (3) the transportation characteristics for hazy pollution in different seasons in this area; (4) the scientific and feasible proposal for the mitigation of hazy pollution in CGWCTS combined with the goal of regional air quality improvement. The research findings might provide the scientific evidences for the accurate estimation of the process of hazy episodes in coastal city group in Southeastern China impacted by fast urbanization and East Asia monsoon, also be in favor of enriching the basic study on atmospheric haze in China.
