Since the industrial revolution, with more fuel use, more biomass burning, more motor vehicle exhaust, the concentration and distribution of both regional and global atmosphere have changed observably. And that leads to problems like global warming, ozone depletion, acid deposition, air quality going down and so on, which have much effect on earth environment and ecosystems, and put huge threat to human development. Therefore, the observation and study of atmosphere components is quite important. Carrying on long-term steady observation of atmosphere components and its relevant qualities is essential for learning atmosphere components and its changing process. Such based studies on atmosphere components changing law, and responding to climate change and disasters, is one of the essential issues of achieving the unity of man and nature both nowadays and in the future.
