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.

调查人员正在使用几台法布里-珀罗仪器研究风和温度中的热层和中间层小尺度结构。 除了绘制上层中层风的水平矢量图外，他们还获得了尽可能高的时间分辨率的风观测结果。 然后，他们研究垂直风特性和相关的事件解决空间/时间的模糊性。 因此，他们研究的具体目标是：（1）对中层上层的矢量风场进行成像，（2）获得中层上层风、温度和排放率的时空变化，以及波动的光谱特征，以及（3）检验假设，即风或温度排放率测量值的分布方差在统计上没有显著变化，在全天空视图中的位置功能。
