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(AGW)。重力波对中层顶区域很重要，因为除其他外，它对动力学的影响以及为该区域提供主要能源。这是一个真正的雪松连接，将对流层与中高层大气连接起来。大气环流主要产生于对流层，沿水平和垂直方向传播到中间层上层和热层下层，对大气辉光层造成扰动。这些扰动充当了AGW的示踪物，因为它们提供了它们的水平波长、视相速度、源方向、幅度和相关的波参数的信号。该项目是ANLC/ALOHA计划的后续研究，将通过参与星火光学距离实验、犹他州立大学和熊湖天文台的测量计划以及通过分析全天数据库中的相位前锋来研究AGW的来源，继续发展重力波探测。

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.
