This project involves the study of atmospheric gravity waves (AGWs) using airglow imaging data. Gravity waves are important to the mesopause region for, among other things, their effect on dynamics as well as a provision of a major energy source for the region. This is a true CEDAR link coupling the troposphere to the middle and upper atmosphere. AGWs, primarily generated in the troposphere, propagate horizontally and vertically to the upper mesosphere and lower thermosphere, causing perturbations to the atmospheric airglow layers. These perturbations act as tracers of the AGWs as they provide a signature for their horizontal wavelength, apparent phase speed, source directions, amplitude, and related wave parameters. This project, a follow-up study to the ANLC/ALOHA program, will continue the evolution of gravity wave exploration through participation in the Starfire Optical Range Experiment, a measurement program at Utah State University and the Bear Lake Observatory, and a study of the sources of AGW through analysis of phase fronts from the all-sky data base.

该项目涉及利用气辉成像数据研究大气重力波。 重力波对中层顶区域很重要，因为除其他外，它们对动力学的影响以及为该区域提供主要能源。 这是一个真正的CEDAR链路，将对流层与中高层大气耦合起来。 AGW主要产生于对流层，水平和垂直传播到上层中间层和下层热层，引起大气气辉层扰动。 这些扰动作为AGW的示踪剂，因为它们提供了它们的水平波长，视相速度，源方向，振幅和相关的波参数的签名。 该项目是ANLC/ALOHA方案的后续研究，将通过参加星火光学测距实验（犹他州州立大学和熊湖天文台的一个测量方案），以及通过分析全天空数据库的相锋来研究AGW的来源，继续推进重力波探测的发展。
