The PIs will develop a novel middle atmosphere temperature lidar that uses broadband tunable solid-state lasers and mesospheric iron as the fluorescence tracer. This system will be rugged and reliable, capable of making observations day and night, and capable of being deployed at remote sites or operated from research aircraft. After its construction, the system will characterize the thermal structure of the middle atmosphere to study iron and calcium in the mesopause region, and study the influence of tides and planetary waves. These observations will substantially improve the limited knowledge of middle atmosphere temperatures, quantify the natural variability, provide crucial tests of middle atmosphere circulation models, and significantly enhance understanding of large scale waves and tides in this region. Finally, the Arctic temperature observations planned will be the first made of the mesopause region at extreme high latitudes.

PI将开发出一种新型的中间气氛温度激光雷达，该温度激光雷达使用宽带可调固态激光器和中层铁作为荧光示踪剂。 该系统将是坚固且可靠的，能够日夜进行观察，并能够在偏远的站点部署或从研究飞机运营。 结构后，该系统将表征中间气氛的热结构，以研究中层区域的铁和钙，并研究潮汐和行星波的影响。 这些观察结果将大大提高对中间大气温度的有限知识，量化自然变异性，提供中间大气循环模型的关键测试，并显着增强对该地区大规模波和潮汐的理解。 最后，计划的北极温度观察将是极端高纬度的间膜区域的第一个。
