The investigators will upgrade recently installed lidars at Arecibo, Puerto Rico, and Juliusruh, Germany, for temperature and radial wind measurements in the mesopause region using atmospheric potassium atoms as tracers. These lidars will then be operated along with a sodium lidar in Fort Collins, Colorado, for at least five nights each season so that the seasonal variations of thermal structures in the mesosphere can be studied. The data will elucidate the global climatology of the mesopause region, as well as other interesting phenomena in the middle atmosphere, such as gravity waves and tides. When the necessary technology for wind and daytime measurements has been developed at Fort Collins, it will be transferred to Arecibo and Juliusruh for the lidars operated at those places.***

研究人员将升级最近在波多黎各的阿雷西博和德国的朱利叶斯鲁安装的激光雷达，使用大气钾原子作为示踪剂测量中层顶区域的温度和径向风。 然后，这些激光雷达将与科罗拉多柯林斯堡的钠激光雷达一起沿着运行，每个季节至少运行五个晚上，以便研究中间层热结构的季节性变化。 这些数据将阐明中层顶区域的全球气候学，以及中层大气中的其他有趣现象，如重力波和潮汐。 当柯林斯堡开发出必要的风和白天测量技术后，将把它转移到阿雷西博和朱利叶斯鲁，用于在这些地方运行的激光雷达。
