Measurement on global changes in atmospheric constituents with optical method

这个项目有两个主要目的；一是继续并进一步推进极地平流层大气化学的研究。另一个是进行初步研究，以了解全球大气化学。为了实现第一个目标，我们于1990年1月在瑞典基律纳对活性氮、臭氧和气溶胶进行了气球观测。在北极化学方面取得了非常重要的科学成果。为了实现第二个目标，我们访问了夏威夷和印度尼西亚的观测点。这些地点被认为对未来的观测很有希望。我们还邀请了阿拉斯加大学的科学家对北极大气环境进行合作研究。我们以这种方式开展的项目将为即将开展的全球环境研究项目“STEP”和“New Research Program”提供很好的基础。

This project has been performed with two major aims; One is to continue and promote further the studies on the atmospheric chemistry of the polar stratosphere. The other is to perform preliminary studies to understand the global atmospheric chemistry. To achieve the first goal, we made balloon observations of reactive nitrogen, ozone, and aerosols in Kiruna, Sweden in January 1990. Very important scientific results on the Arctic chemistry have been obtained. To achive the second goal, we visited observational sites of Hawaii and Indonesia. These sites have been found promising for future observations. We have also invited scientists from University of Alaska to make cooperative research on the atmospheric environment in the Arctic. The project we have performed in this way will provide very good basis for the coming programs "STEP" and "New Research Program" on global environment.
