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.

这项研究继续努力将先进的干涉光谱方法应用于航空学研究。 该研究强调利用具有双和三标准具系统的 CCD 探测器的更高灵敏度的应用。 其中包括地冕 Balmer-alpha 夜光和 (OI)6300 日光测量。 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磨石山的光学设施，在那里测量结果将定期进行协调并与其他光学和雷达测量结果进行比较。 计划中的其他测量将延长地冕巴尔默-α强度测量的长基线，以研究太阳周期变化以及预测外层氢随较低大气甲烷累积的变化。
