Ground-based Optical Aeronomy Facility Instrumentation: A Fabrication and Community Support Program

近年来，探测和分析高层大气光发射的技术取得了迅速的进展，从而得出与该地区光化学和动力学有关的物理参数。电荷耦合装置（CCD）可以同时测量许多波长，比光电倍增管的灵敏度更高，并且通过计算机控制和数字读取数据到存储器中，现在可以检索到的高层大气排放的信息量比以前大了大约两个数量级。作为大气区域耦合、能量学和动力学（CEDAR）计划的一部分，利用CCD技术构建了一个新的光谱仪。该装置还包括几个小型成像仪，它们提供摄谱仪所指向的结构（如极光形式）的单色图像。与其他机构的研究人员合作，计划进行几次高层大气排放观测活动，并将使用一种类似的仪器在轨道上进行观测，这样就可以同时对相同面积的空间进行地面和卫星观测。

Rapid advances have been made in recent years in the technology of detecting and analyzing optical emissions from the upper atmosphere, to yield physical parameters related to the photochemistry and dynamics of the region. The charge-coupled device (CCD) allows the simultaneous measurement of many wavelengths with higher sensitivity than photomultipliers, and with computer control and digital readout of data into memory, the amount of information now retrievable on upper atmosphere emissions is around two order of magnitude greater than previously. As part of the CEDAR (Coupling, Energetics and Dynamics of Atmospheric Regions) program, A new spectrograph has been constructed utilizing CCD technology. The unit also includes several small imagers, that provide monochromatic images of structures (such as auroral forms) that the spectrograph is being directed toward. Several campaigns of observations of upper atmosphere emissions are planned in conjunction with investigators from other institutions, and a similar instrument is to make observations from orbit, so that simultaneous ground and satellite observations of the same volume of space will be possible.
