CEDAR: A Calibration 'Facility' for CEDAR (Coupling, Energetics, and Dynamics of Atmospheric Regions) Optical Aeronomy

测量气辉的仪器的绝对灵敏度对于将光子计数率转换为发射亮度和发射物种丰度是必要的。同样，必须准确知道传输通带，这不仅是为了确定正确的灵敏度，也是为了提取温度和风信息。中央校准设施的建立解决了整个航空界没有光学校准或光学校准不一致的突出问题。对所有地点的光学数据进行统一和准确的校准尤为迫切，因为同化模式努力整合地面数据，以便对全球运输和风暴应对情况进行描述，包括空间天气预报。该设施配备了两个标准光源、两个标准探测器和一个干涉滤光片校准仪器。这些光源机械上坚固耐用，不受震动和冲击，可以在设施中使用，也可以运往偏远地点的调查人员。可以将干扰滤光片运送到校准设施，以实现可靠且统一的通带和阻挡校准。

The absolute sensitivity of instruments measuring the airglow is necessary for the conversion of photon count rates to emission brightness and to emitting species abundances. Similarly, transmission pass bands must be precisely known, not only for proper sensitivity determination, but also for extracting temperature and wind information. Establishment of a central calibration facility addresses the outstanding problem of absent or inconsistent optical calibration across the aeronomy community. Unified and accurate calibration of optical data at all sites is particularly urgent as assimilative models strive to integrate ground-based data for global descriptions of transport and storm-response, including Space Weather forecasting. The facility features two standard light sources, two standard detectors, and an interference filter calibration instrument. The light sources are mechanically robust against vibration and shock, and can be used at the facility or shipped to investigators at remote sites. Interference filters can be shipped to the calibration facility for reliable and uniform pass band and blocking calibration.
