Vertical Distribution of Gaseous in Environmental Atmosphere at Mt. Fuji Using Passive Sampler

The vertical distributions of the concentrations of O 3 , NO, NO 2 and SO 2 at the experimental sites of Mt. Fuji in Japan were measured by the passive sampler from July to November in 2007. When the air mass came from the Asian continent, the vertical distribution of the concentration of O 3 increased with altitude up to 67.2ppbv at 3240m, while the vertical distribution of the concentration of O 3 decreased with altitude when the air mass came from the Pacific. The concentrations of NO and NO 2 increased with the altitude more than 2000 m. This phenomenon depended on the altitude. The SO 2 fluctuation was seemed to depend on the direction, where an air mass came and also on the altitude. When an air mass came from the continent, the concentration of SO 2 increased with altitude as O 3 , and when an air mass came from the Pacific, the increase of the concentration with altitude was found when the altitude was more than 2000m as NO and NO 2 . The vertical distribution of temperature and the humidity indicated changes of an air mass at 1700, 2500 and 3200m. The vertical distributions of NO, NO 2 and SO 2 and the meteorological data such as temperature and humidity suggested that an atmospheric boundary layer existed near an altitude of 2000 meters.
