Aerosol characterization by using Mt. Fuji as an observation tower

东亚地区是一个新兴的工业化地区，排放的气溶胶及其前体气体种类繁多，成分各异。它们显示出深刻的时间和空间变化，主要是由于其相对较短的停留时间。为了更好地评估气候影响等，观测气溶胶特性（浓度、粒度分布、成分、光学特性以及与云雾过程的关系等）因此，在自由对流层中，是必不可少的。因此，对气溶胶及其前体进行了研究。富士山是日本最高的山峰（海拔3776米）。在山顶（海拔3776米）进行了三次强化观测活动，7.8点（3400米a.s.1.）Tarou-bou（1300m a.s.1.），2005年至2007年夏季，山。结果发现，气溶胶和前体气体被当地的山脉和山谷风所统治，在夜间处于自由对流层条件下。发现的物种的起源是 ...更多信息 在高层大气中，白天和黑夜似乎不同。此外，如果锋面活动为输送创造了有利条件，即使在夏季也可以观测到各种大陆性污染物。山和山谷蜿蜒在Mt.通过简单的地面观测设备在山体和山脚下的地面观测和无线电探空的比较，首次对富士山进行了定量化研究。根据被动采样器测得的O_3和NO_x垂直平均廓线，夏季混合层的发展尺度约为2km。由于污染源少，山脚下。包括太郎府在内的富士山在城市空气污染方面可以提供参考。在那里将有可能评估生态系统对酸雨和雾的反应。虽然现有的大气传输模式对观测数据进行了概括，但还应使用替代的区域传输模式，以确定喜马拉雅山的地理位置。富士是更恰当地表达，在未来。少

East Asia is such a growing industrial region that many kinds of the aerosol and its precursor gas haying different composition are emitted. They display profound temporal and spatial variations due mainly to their relatively short residence time. For the better assessment of climatic impacts, etc., observations on aerosol characteristics (concentration, size distribution, composition, optical property and relations to cloud and fog processes, etc.) in the free troposphere are thus essential. Hence, research on aerosol and its precursor was carried out at Mt. Fuji, an isolated highest peak in Japan (3776m a.s.1.).Three intensified observation campaigns were carried out at the summit (3776m a.s.1.), 7.8 point (3400m a.s.1.) and Tarou-bou (1300m a.s.1.), etc. of the mountain during summers of 2005-2007. It was found that the aerosol and the precursor gas are ruled by local mountain and valley winds, being under a free tropospheric condition during night. The origin of the species found i … More n the upper atmosphere seems different between night and day. Moreover, various continental pollutants could be observed even in summer if the frontal activity creates favorable conditions for the transport. The mountain and valley winds at Mt. Fuji were quantified for the first time by comparing the surface observations by simple equipments on the mountain body with those at the mountain foot and radiosounding. A scale of the developed mixed layer turned out to be, from vertical averaged profile of 0_3 and NO_x by passive samplers, about 2km during summer. Because of few pollution sources, foot of Mt. Fuji including Tarou-bou can serve reference concerning the air pollution of the city. Evaluation of ecosystem response against acid rain and the fog would be possible there. Although the observational data was generalized by a present atmospheric transport model, alternative regional transport model should be used, by which geography of Mt. Fuji is more properly expressed, in the future. Less
