Overview:
Rapid developments in Asia have resulted in large increases in the emissions
of trace gases and aerosols, and understanding their impacts on the
oxidizing capacity and the radiative budget is one of the foci of
international atmospheric chemistry and climate research. Our research has
thus initially aimed to understand the atmospheric distributions of
chemically important trace gases and aerosols and the processes that shape
the temporal-spatial distributions. We have carried out extensive field
measurement and analysis of regional air pollution such us ozone, haze, and
acid rain. The study regions include the Pearl River delta (including Hong
Kong), Yangtze River delta, the Huabei plains (including Beijing), which are
the three economically most important regions in China, maritime regions of
the South China Sea and the western Pacific, and the Qinghai-Tibetan
Plateau.
These studies provide valuable data for documenting chemical changes caused
by the rapid industrialization in Asia. Using statistical, meteorological,
and chemical models we have studied emission, transport, and chemical
processes that influence the atmospheric abundance of trace gases and
aerosols, and assessed their impact on visibility and crop yields. Our
research contributed to international atmospheric chemistry programs such us
PEM-West B, China-MAP, TRACE-P, ACE-Asia, IGAC-Megacity, and ABC. We are
also involved in a significant way in an on-going China¡¦s National Basic
Research Programme (the 973 programme)¡¦s research project on acid rain
pollution and control (http://www.craes.cn/cn/xiangmu/973_01.html).
