This project supports the operation and maintenance of four Fabry-Perot Doppler Imagers, two at the Millstone Hill Observatory in Massachusetts and two at the Arecibo Observatory in Puerto Rico. These instruments provide data on the behavior of the neutral components of the Earth's thermosphere, and contribute to studies of interactions among the Earth's ionosphere and thermosphere in response to solar forcing as a system. This will address the distribution of energy and momentum throughout different latitudes and layers of the atmosphere. Data and operation will be centralized through a client-server architecture that allows for remote operation, data collection and automated analysis. Data will continue to be published to the web and Madrigal database daily, within hours of observation. The project will provide educational opportunities for undergraduate students through collaborations. SSI is pursuing non-traditional educational opportunities to educate the public about space science and optics in general. The ASTRA team will use the Millstone Hill and Arecibo data to investigate the magnitude, occurrence rate and variability of the midnight temperature maximum (MTM), and the annual and semiannual variability of the upper thermosphere. These results will be compared with TIMEGCM model output. Thermospheric vertical winds will be measured at each location using two different techniques, a direct line-of-sight technique and the Burnside technique where vertical winds are inferred from the horizontal wind gradient. When available these vertical winds will be compared to vertical motion measured by the incoherent scatter radars at each location. These observations allow for the inter-comparison and verification of the veracity of different measurement techniques and will ultimately allow for a better understanding of the 3-d dynamics of the thermosphere.

该项目支持四个法布里-珀罗多普勒成像仪的运行和维护，其中两个位于马萨诸塞州的磨石山天文台，两个位于波多黎各的阿雷西博天文台。这些仪器提供有关地球热层中性成分行为的数据，并有助于研究地球电离层和热层之间作为一个系统对太阳强迫的相互作用。这将解决能量和动量在不同纬度和大气层中的分布问题。 数据和操作将通过客户端-服务器架构进行集中，该架构允许远程操作、数据收集和自动分析。数据将继续每天在观察数小时内发布到网络和 Madrigal 数据库。该项目将通过合作为本科生提供教育机会。 SSI 正在寻求非传统教育机会来教育公众有关空间科学和光学的知识。 ASTRA团队将利用磨石山和阿雷西博的数据来研究午夜最高气温（MTM）的幅度、发生率和变化，以及上层热层的年度和半年度变化。这些结果将与 TIMEGCM 模型输出进行比较。将使用两种不同的技术在每个地点测量热层垂直风，即直接视线技术和伯恩赛德技术（从水平风梯度推断垂直风）。 如果可用，这些垂直风将与每个位置的非相干散射雷达测量的垂直运动进行比较。 这些观测结果可以对不同测量技术的准确性进行相互比较和验证，并最终有助于更好地了解热层的 3 维动力学。
