CEDAR: Ground-Based Imaging of Upper Atmospheric Wind and Temperature Fields in the Auroral Zone

地球物理研究所开发的一种新型全天候成像法布里-珀罗光谱仪对高层大气风场和温度场进行地面成像。PI将使用该仪器探索热层风和温度的小规模结构，特别是在极光弧附近。此外，现有的探测器将被CCD相机取代。这将提高仪器的灵敏度，因此可以用更短的曝光获得数据，减少由于该项目将检查的小尺度特征的平流涂抹而产生的不确定性

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.***
