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Fabry-Perot多普勒成像仪的操作和维护，其中两个在马萨诸塞州的米尔斯通山天文台，两人在波多黎各的Arecibo天文台。这些仪器提供了有关地球热层中性成分的行为的数据，并有助于研究地球电离层和热层之间的相互作用，以响应太阳能强迫作为系统。这将解决在大气的不同纬度和层中能量和动量的分布。 数据和操作将通过客户端服务器体系结构集中，该架构允许远程操作，数据收集和自动分析。在观察几小时内，数据将继续发布到网络和Madrigal数据库。该项目将通过合作为本科生提供教育机会。 SSI正在寻求非传统的教育机会，以教育公众有关太空科学和光学的教育。 Astra团队将使用Millstone Hill和Arecibo数据来研究午夜温度最大（MTM）的大小，发生率和变异性以及上部热层上部的年度变异性。这些结果将与TimeGCM模型输出进行比较。热层垂直风将使用两种不同的技术在每个位置进行测量，即直接视线技术和Burnside技术，其中从水平风梯度推断出垂直风。 如果可用，将将这些垂直风与每个位置的不一致散点雷达测量的垂直运动进行比较。 这些观察结果允许对不同测量技术的准确性进行比较和验证，并最终可以更好地了解热圈的3-D动力学。
