Multispectral Airglow Observations of Gravity Waves during the August 2017 Total Solar Eclipse

在日食期间，当月亮经过地球和太阳之间时，阴影导致地球大气层沿着经历日全食的狭长地带冷却。长期以来，人们一直假设内部重力波（GWs）会因突然的水平温度梯度而产生，然后从阴影区域传播出去。PI是一名早期的职业女性，她将在2017年8月21日北美日全食之前、期间和之后的不同位置部署两台成像光谱仪，观察日全食前后的气辉光。第三台成像仪将位于远离日食区域的地方，以提供对照数据集。科学目标是研究日食驱动的重力波在气辉中的演变。该实验有望提供有关大气如何对臭氧加热和电离光子通量的快速变化作出反应的信息。这项工作也将有助于讨论在日食期间引力波在哪里形成和传播。

During a solar eclipse, when the Moon passes between the Earth and the Sun, the shadow results in cooling of the Earth's atmosphere along the swath that experiences a total eclipse. It has long been hypothesized that internal gravity waves (GWs) would be generated in response to sudden horizontal temperature gradients, that would then propagate away from the region of the shadow. The PI, who is an early career female, will deploy two imaging spectrographs at separate locations along the line of totality that will observe airglow before, during, and after the North American total solar eclipse on August 21, 2017. A third imager will be located far away from the eclipsed area, to provide a control dataset. The science objective is to study eclipse-driven gravity wave evolution in the airglow. This experiment is expected to provide information about how the atmosphere reacts to fast changes in ozone heating and ionizing photon flux. The work will also contribute to the debate about where gravity waves form and propagate during a solar eclipse.
