CEDAR: Airglow Imaging of Atmospheric Gravity Waves

该项目涉及利用气辉成像数据研究大气重力波（AGWs）。重力波对中间层顶区域很重要，因为它们对动力学的影响以及为该区域提供主要的能量来源。这是连接对流层和中高层大气的真正的雪松链路。AGWs主要产生于对流层，在水平和垂直方向上向上层中间层和下层热层传播，对大气气辉层造成扰动。这些扰动作为agw的示踪剂，为其水平波长、视相速度、源方向、振幅和相关波参数提供了信号。该项目是ANLC/ALOHA项目的后续研究，将通过参与Starfire光学距离实验（Starfire Optical Range Experiment），犹他州立大学和熊湖天文台的测量项目，以及通过分析来自全天空数据库的相位前沿来研究AGW的来源，继续推进重力波探测的发展。

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.
