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.

测量气辉的仪器的绝对灵敏度是将光子计数率转换为发射亮度和发射物种丰度所必需的。同样，必须精确地知道传输带，这不仅是为了适当地确定灵敏度，也是为了提取温度和风的信息。建立一个中央校准设施解决了整个航空界光学校准缺失或不一致的突出问题。由于同化模型努力整合地面数据，以便对包括空间天气预报在内的全球运输和风暴反应进行描述，因此在所有站点对光学数据进行统一和准确的校准尤为紧迫。该设备具有两个标准光源，两个标准探测器和一个干涉滤光校准仪器。该光源具有抗振动和冲击的机械强度，可以在设施中使用，也可以运送给偏远地区的调查人员。干扰滤波器可以运送到校准设施进行可靠和均匀的通带和阻塞校准。
