This proposal sets forth a three-year plan to study the circulation of the Arctic atmosphere during the upcoming IPY. Specifically, this is an observational study that combines satellite measurements, lidar measurements, and meteorological soundings and analyses to study the troposphere, stratosphere, and mesosphere. The study is an international collaboration between investigators at six institutions in Canada, Germany, Japan and the United States. The satellite observations yield global synoptic-scale temperature measurements of the mesosphere and upper stratosphere while the meteorological soundings and analyses provide global synoptic-scale measurements of the troposphere and lower stratosphere. An international network of four Rayleigh lidars located in observatories at Andoya, Norway (69N, 16E), Chatanika, Alaska (65N, 147W), Eureka, Nunavut (80N, 86W), and Kangarlussuaq, Greenland (67N, 51W), will provide a chain of high-resolution temperature measurements from the eastern Arctic to the western Arctic. The lidars will yield high-resolution measurements of the structure and circulation of the Arctic stratospheric vortex, the Aleutian anticyclone, the stratospheric surf-zone, planetary waves, tides, and gravity waves that are corroborated by the synoptic-scale satellite and meteorological observations. The proposed activity will provide a comprehensive analysis of the circulation of the Arctic atmosphere that will directly address the following specific studies; the structure, evolution, and variability of polar vortices and anticyclones, coupling and feedbacks between waves and large-scale circulation, links between the middle and lower atmosphere, atmospheric teleconnections, and modes of variability. This study will provide data and analyses in support of studies of ozone depletion, stratospheric climate, climate oscillations in the Arctic, and long-range horizontal and vertical transport in the Arctic. The proposed activity will support education and training of students in science and engineering. The activity will jointly draw on and contribute to research infrastructure in the Arctic, enhance international collaborations, and promote collaboration among observers, modelers and theorists. The research results will be integrated into the University of Alaska and University of Colorado IPY Education and Outreach programs and disseminated through a variety of professional, educational, and outreach programs.

该提案制定了一项为期三年的计划，以研究即将到来的IPY期间北极气氛的循环。具体而言，这是一项观察性研究，结合了卫星测量，激光雷达测量以及气象声音和分析，以研究对流层，平流层和中层。这项研究是加拿大，德国，日本和美国六个机构的研究人员之间的国际合作。卫星观测结果产生了中层和上层平流层的全球概要温度测量值，而气象声和分析则提供了对流层和下层平流层的全球概要测量。一个由四个瑞利雷达的国际网络，位于挪威安多亚（69n，16e），阿拉斯加查塔尼卡（65n，147w），尤里卡（Eureka），努纳武特（80n，86w）和kangarlussuaq，greenland（67n，51W），将乘坐高空的温度悬浮在eristion can arrinct can ar arrinct arterions arrigation can ar ar ar ar ar ar ar ar ar ar ar ar ar ar ar ar ar ar ar ar ar ar ar ar ar ar ar ar ar ar ar ar aras，art arrinct arrigation can arrigation can arrigation can激光雷达将对北极平流层涡流的结构和循环产生高分辨率的测量，这是由概要级卫星和气象学观察所证实的。拟议的活动将对北极气氛的循环进行全面分析，该分析将直接解决以下特定研究；极性涡流和反气旋，波和大规模循环之间的耦合和反馈的结构，演变和变异性，中间大气和下大气之间的联系，大气远程连接以及可变性模式。这项研究将提供数据和分析，以支持研究臭氧耗竭，平流层气候，北极气候振荡以及北极远程和垂直转运的研究。 拟议的活动将支持科学和工程学学生的教育和培训。该活动将共同利用并为北极的研究基础设施做出贡献，增强国际合作，并促进观察家，建模者和理论家之间的合作。 该研究结果将融入阿拉斯加大学和科罗拉多大学IPY教育和外展计划，并通过各种专业，教育和外展计划进行分发。
