I：Seek Understanding of atmospheric chemistry at the molecular level using techniques and concepts of physical chemistry
II：Focus at the interface between chemistry and atmospheric science.
(1) Seek the "new" chemistry of the atmosphere；
(2) Exploration of how atmospheric gas components and aerosol impact atmospheric and environmental problems such as urban smog stratospheric ozone depletion climate change health etc.
III： Development and application of the advanced instrumentation (real-time on-line and quantitative measurements)
