抄録

In order to obtain information on the vertical distributionof ozone concentration in the lower atmosphere, field experiments were conducted at Mt. Fuji located on the prefecture boundary of Shizuoka and Yamanashi. The ozone concentration was monitored by Ogawa passive samplers at 20points from base to top of Mt. Fuji during the period from 12 to 20 July, 2005. The temporal variation of ozone concentration was also analyzed by the automatic monitoring data at three urban points on the base of Mt. Fuji and the top of Tanzawa about 30 km East from Mt. Fuji.<BR>The estimated average ozone concentrations were about 20 ppbv for the mixing layer and about 40 ppbv for the free atmosphere; these values agreed with the recently reported values observed at mountainous areas in the summer season. The estimated average ozone concentrations were about 20 ppbv for three urban points and about 40 ppbv for the top of Tanzawa, with a significant diurnal variation. It was considered that the mid-slop of Mt. Fuji was influenced by local air pollution occasionally depending on the meteorological condition.<BR>The passive sampler would be useful by coupling an UV-photometric monitor to analyze the transport of ozone and oxidant in the lower atmosphere.
