CEDAR: Clustered Measurements of Space and Temperature Variability in the Winds of Upper Mesospheric and Upper Thermospheric Heights in the Auroral Zone

研究人员正在使用几台法布里-珀罗仪器来研究风和温度下的热层和中层小尺度结构。除了绘制中上层风的水平矢量图外，它们还以尽可能高的时间分辨率获得风观测。然后，他们研究垂直风的特征和相关的出现，以解决空间/时间模糊性。因此，他们研究的具体目标是：(1)对中间层上层的矢量风场进行成像，(2)获得中间层上层风、温度和排放率的时空变化以及波动的光谱特征，(3)检验关于风或温度排放率测量的分布方差作为全天视图中位置的函数在统计上没有显著变化的假设。

The investigators are using several Fabry-Perot instruments to study thermospheric and mesospheric small scale structures in wind and temperature. In addition to mapping horizontal vectors of upper mesospheric wind, they obtain wind observations at the highest possible time resolution. Then, they study vertical wind characteristics and associated occurrences resolving spatial/temporal ambiguities. Thus, the specific objectives of their research are (1) imaging the vector wind field in the upper mesosphere, (2) obtaining temporal and spatial variances in upper mesospheric winds, temperatures and emission rates, as well as the spectral characteristics of fluctuations, and (3) testing the hypothesis that there is no statistically significant variation in distributed variance of wind or temperature emission rate measurements as a function of position in the all-sky view.
