A Phase II CEDAR Program of Groundbased Airglow Spectroscopyat McDonald Observatory

了解变化的原因和重要性 由于各种自然和人为因素， 对这些变化的观察需要在 不同的海拔高度。 一种技术是 研究的是光学曙暮光期间的观测， 由太阳辐射产生的辐射。 这些的倒置 太阳低角变化的观测给出了 所观察到的特定发射的高度变化。 该项目是一个合作项目的观察和 建模以尝试获得O、O2和N2的高度分布 浓度以及温度和综合太阳能 通量该数据库还将提供以下方面的宝贵信息： 共轭光电子通量与半球间输运 流程. *** //

To understand the causes and importance of the changes occurring in our atmosphere due to a variety of natural and man made influences requires observations of these changes at different altitudes on a global basis. One technique being investigated is the observation during twilight of optical emissions produced by solar radiation. The inversion of these observations with changing solar depression angle gives the height variation of the particular emission being observed. This project is for a collaborative program of observations and modeling to attempt to obtain height profiles of the O, O2 and N2 concentrations as well as temperature and the integrated solar flux. The data base will also provide valuable information on the conjugate photoelectron flux and interhemispheric transport processes. *** //
