Analysis of Twilight Airglow Measurements

雪松计划的主要目标之一是发展一种全球技术，以确定高层大气中不同大气成分的高度分布及其随时间的变化。目前正在研究的一种很有前途的技术是利用黄昏期间与原子氧和分子氮有关的发射强度变化来提供这一信息。本项目概述的工作将使用建模技术将这些黄昏观测结果转化为组成密度高度分布。这种方法的成功将导致一种简单的技术，可在全球范围内广泛使用，以确定高层大气的成分动力学。3/3/89 / /

One of the major goals of the CEDAR program is to develop a global technique for determining the height distribution and its variation with time of the different atmospheric constituents in the upper atmosphere. One promising technique which is being pursued is to use the variation in emission intensity associated with atomic oxygen and molecular nitrogen during twilight to provide this information. The work outlined in this project will use modeling techniques to invert these twilight observations into constituent density height distributions. The success of this approach will lead to a simple technique which can be widely used around the globe to determine the compositional dynamics of the upper atmosphere. 3/3/89//
