Austral High-Latitude Mesospheric and Thermospheric Dynamics and Thermodynamics

该奖项将继续在南极运行法布里-珀罗涉仪，以测量中间层上层和热层下层(约100公里高度)中性大气中的温度和风。极点的大气条件相对简单，这使它成为一个理想的地方，可以更多地了解驱动高层大气动力学行为的机制。在较低纬度，加热和冷却的昼夜效应以及阳光引起的电离变化使动态情况变得非常复杂；而在极地，这些混淆的影响是不存在的。因此，通过比较这两个区域，可以从大的每日信号中分离出全局效应。在运行期间，将发射温差、电离层、中间层能量和动力学(TIMED)卫星，南极测量将补充航天器的测量。

This award will continue the operation of a Fabry-Perot interferometer at South Pole for the purpose of measuring temperature and winds in the neutral atmosphere in the upper mesosphere and lower thermosphere (~100 Km altitude). The relative simplicity of the atmospheric conditions at the Pole makes it an ideal place to learn more about the mechanisms that drive the dynamical behavior of the upper atmosphere. At lower latitudes, the diurnal effects of heating and cooling and changes in the ionization caused by sunlight make the dynamical situation very complex; whereas, at the Pole these confounding effects are absent. Therefore, by comparing the two regions the global effects can be separated from the large daily signals. During the period of operation, the Thermospere, Ionosphere, Mesosphere Energetics and Dynamics (TIMED) satellite will be launched, and the South Pole measurements will complement those of the spacecraft.
