A new type of All-Sky Imaging Fabry-Perot spectrometer developed at the Geophysical Institute performs ground-based imaging of upper atmospheric wind and temperature fields. The PI will use this instrument to explore small-scale structures in thermospheric wind and temperature, particularly near auroral arcs. In addition, the existing detector will be replaced with a CCD camera. This will improve the instrument's sensitivity, so data can be obtained with shorter exposures, reducing uncertainty due to advective smearing of the small-scale features this project will examine.***

地球物理研究所开发的新型全天空成像法布里-珀罗光谱仪对高层大气风场和温度场进行地面成像。 PI将利用这一仪器探索热层风和温度的小尺度结构，特别是极光弧附近。 此外，现有的探测器将被CCD摄像机取代。 这将提高仪器的灵敏度，因此可以在更短的曝光时间内获得数据，减少由于该项目将检查的小尺度特征的平流拖尾而导致的不确定性。
