Southern Hemisphere Mid-Latitude Ground-Based Investigationsof the Dynamics and Thermodynamics of the Mesosphere and Thermosphere

由于水平输送和耦合的核心重要性，必须在全球范围内研究高层大气，包括中间层和热层的动力学和热力学。到目前为止，大多数研究都集中在北半球，而南半球的研究仅限于南极洲。该奖项是对中间层和低热层中风循环的研究。一台光学高分辨率光谱仪将在坎特伯雷大学的约翰山天文台(位于新西兰)放置并运行。华盛顿坎特伯雷大学和阿拉斯加大学的这项国际合作将研究南半球中高纬度过渡地区的高层大气动力学。所获得的观测结果将借助NCAR含时热层和电离层全球环流模式(TIGCM)的模拟进行解释。*//

Investigation of the dynamics and thermodynamics of the upper atmosphere including the mesosphere and thermosphere must be done on a global scale because of the central importance of horizontal transport and coupling. Most of the studies to date have focused on the Northern Hemisphere, those in the Southern Hemisphere have been limited to Antarctica. This award is for studies of wind circulation in the mesosphere and lower thermosphere. An optical high-resolution spectrometer will be placed and operated at the University of Canterbury's Mount John Astronomical Observatory (in New Zealand). This international collaboration between the University of Canterbury, Washington, and Alaska will study upper atmospheric dynamics of the transition region between mid and high latitudes in the Southern Hemisphere. Observations obtained will be interpreted with the aid of simulation from NCAR time dependent coupled thermosphere and ionosphere global circulation model (TIGCM). *** //
