CEDAR计划的主要目标之一是开发一个 确定高度分布的全球技术及其应用 不同大气成分随时间的变化， 上层大气。 一种很有前途的技术， 所追求的是使用与发射强度相关的变化， 原子氧和分子氮在暮光之城， 提供这些信息。 本项目概述的工作将 利用建模技术来反演这些暮光观测结果 组成密度高度分布。 的成功 这种方法将导致一种简单的技术， 在地球仪中用来确定 上层大气。 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//
