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，传输通带必须精确已知，不仅用于正确的灵敏度确定，而且用于提取温度和风信息。 建立一个中央校准设施解决了整个高层大气科学界缺乏或不一致的光学校准的突出问题。 统一和准确地校准所有站点的光学数据尤为紧迫，因为同化模型努力整合地面数据，用于对传输和风暴反应的全球描述，包括空间气象预报。 该设施具有两个标准光源，两个标准探测器和一个干涉滤光片校准仪器。 这些光源在机械上坚固耐用，能够抵抗振动和冲击，可以在设施中使用，也可以运送到偏远地点的研究人员。 干涉滤光片可以运送到校准设施进行可靠和统一的通带和阻塞校准。

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.
