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.

该提案提出了一项三年计划，以研究即将到来的IPY期间北极大气环流。具体来说，这是一项结合卫星测量、激光雷达测量和气象探测和分析来研究对流层、平流层和中间层的观测研究。该研究是加拿大、德国、日本和美国六个机构的研究人员之间的国际合作。卫星观测产生中间层和平流层上层的全球天气尺度温度测量，而气象探测和分析则提供对流层和平流层下层的全球天气尺度测量。位于挪威安多亚（北纬 69°，东经 16°）、阿拉斯加查塔尼卡（北纬 65°，西经 147°）、努纳武特尤里卡（北纬 80°，西经 86°）和格陵兰坎加鲁斯瓦克（北纬 67°，西经 51°）的四个瑞利激光雷达天文台组成的国际网络将提供从北极东部到北极西部的一系列高分辨率温度测量。激光雷达将对北极平流层涡旋、阿留申反气旋、平流层冲浪区、行星波、潮汐和重力波的结构和环流进行高分辨率测量，并得到天气尺度卫星和气象观测的证实。拟议的活动将对北极大气环流进行全面分析，从而直接开展以下具体研究；极地涡旋和反气旋的结构、演化和变化，波与大尺度环流之间的耦合和反馈，中层和低层大气之间的联系，大气遥相关和变化模式。这项研究将为臭氧消耗、平流层气候、北极气候振荡以及北极远程水平和垂直输送的研究提供数据和分析。 拟议的活动将支持科学和工程学生的教育和培训。该活动将共同利用和促进北极的研究基础设施，加强国际合作，促进观察者、建模者和理论家之间的合作。 研究成果将纳入阿拉斯加大学和科罗拉多大学的 IPY 教育和外展项目，并通过各种专业、教育和外展项目进行传播。
