A recent analysis of data acquired viewing the Earth limb edge-on from the space shuttle has demonstrated that the present model of the nightglow emission is incomplete. The observations were made by the Arizona Airglow Experiment (GLO). It uses a new technique referred to as "hyperspectral imaging" in which vertical profiles of all of the prominent nightglow emissions are recorded simultaneously.This proposal requests support to continue the analysis of archival data with the main purpose of providing a more appropriate nightglow model. A review of all present model parameters will be undertaken. That will be followed by static and finally dynamic representations of nightglow condition. The GLO data archive is extensive. Many conditions have been observed that will be used to constrain the model process.

最近对从航天飞机上观察地球边缘获得的数据的分析表明，目前的夜辉发射模型是不完整的。这些观测是通过亚利桑那州的气辉实验(GLO)进行的。它使用一种称为“高光谱成像”的新技术，同时记录所有突出的夜辉发射的垂直剖面。这项提议要求提供支助，继续分析档案数据，主要目的是提供一个更合适的夜辉模型。将对所有现有的模型参数进行审查。然后是静态的，最后是动态的夜光条件表示。GLO的数据档案非常广泛。已经观察到了许多条件，这些条件将用于约束模型过程。
