Air quality issues are the result of interplay between the following factors: chemical reactions, climate, and mass transport. To reduce the negative environmental impact of atmosphere, we need to identify as well as understand the reaction mechanisms that occur in the atmosphere and recognize the effect of these mechanisms on the environment as a whole. The research our laboratory performs is based on the belief that new interpretations of homogeneous and heterogeneous reactions occurring in the troposphere and stratosphere are important in the development of countermeasures against global warming. Thus, our laboratory uses several methods to conduct atmospheric chemistry research and to perform high-sensitivity measurement of atmospheric trace species.|

Trace gas analysis has a key role in investigation of the atmospheric environment. One of the goal of our laboratory is to develop new analytical methods to understand the fate of the atmospheric environment. |
