9302086 Torr Under a previous award, a new photometric technique was developed which allows observations of weak airglow signals to be observed in the daytime. Such measurements made at twilight provide a means of retrieving thermospheric composition and temperature and a scaling factor for the solar EUV flux. A prototype of the instrument was designed, fabricated and tested. In the continuing award, tests will be conducted with the instrument in Huntsville, Alabama, and at McDonald Observatory, in Texas. This will allow assessment of the effects due to the underlying water vapor absorption features which are not as severe in the arid climate at McDonald. These measurements will provide important information for the interpretation of atmospheric composition and temperature data. ***

[302086]根据先前的一项奖励，一种新的光度测定技术被开发出来，可以在白天观测到微弱的气辉信号。这种在黄昏进行的测量提供了一种获取热层成分和温度的方法，以及太阳极紫外通量的比例因子。设计、制造并测试了该仪器的原型。在后续的奖励中，将在阿拉巴马州的亨茨维尔和德克萨斯州的麦克唐纳天文台对该仪器进行测试。这将允许评估由于潜在的水汽吸收特征而造成的影响，而这在麦克唐纳的干旱气候中并不那么严重。这些测量将为解释大气成分和温度数据提供重要信息。＊＊＊
