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. *** //

要了解由于各种自然和人为影响而导致大气层发生变化的原因和重要性，需要在全球不同海拔高度观测这些变化。 正在研究的一项技术是在黄昏期间观察太阳辐射产生的光发射。 这些观测值随太阳俯角变化的反演给出了所观测到的特定发射的高度变化。 该项目是一个观测和建模合作项目，旨在尝试获得 O、O2 和 N2 浓度的高度剖面以及温度和综合太阳通量。该数据库还将提供有关共轭光电子通量和半球间传输过程的有价值的信息。 *** //
