CEDAR: Spectroscopic Studies in Aeronomy Using Advanced Interferometric Techniques

这项研究继续努力将先进的干涉光谱方法应用于空气动力学研究。这项研究强调了利用双标准具和三标准具系统的CCD探测器提高灵敏度的应用。其中包括地冕巴尔默-阿尔法夜辉和(OI)6300白辉的测量。一个主要目标是全面验证我们的白天测量结果。该系统将被转移到马萨诸塞州米尔斯通山的光学设施，在那里测量将定期进行协调，并与其他光学和雷达测量进行比较。计划中的其他测量将延长地冕Balmer-Alpha强度测量的长基线，目的是研究太阳活动周期的变化和预测的外层氢随低层大气甲烷积聚的变化。

This research continues efforts to apply advanced interference spectroscopic methods for studies in aeronomy. The study emphasizes applications that take advantage of the improved sensitivity of a CCD detector with double and triple etalon systems. These include geocoronal Balmer-alpha nightglow and (OI)6300 dayglow measurements. A primary goal is the full validation of our daysky measurements. The system will be moved to the optical facility at Millstone Hill in Massachusetts where measurements will routinely be coordinated and compared with other optical and radar measurements. Other measurements planned will extend the long baseline of geocoronal Balmer-alpha intensity measurements for the purpose of studying solar cycle variations and the predicted variation of exospheric hydrogen with lower atmosphere methane buildup.
