Understanding and predicting thermospheric winds and temperatures during all conditions of space weather activity is important in the determination of satellite drag. The system proposed herein will yield unprecedented measurements of winds and temperatures beyond that which are currently available, leading to transformational changes in the understanding of not only satellite drag, but of a myriad of outstanding questions in the space sciences. The wind measurements have societal significance as they are important for space weather research and global circulation models to understand and predict space weather. Deployment, operation, and analysis of the data from this proposed system will enable undergraduate, graduate, and post-graduate opportunities in contemporary STEM topics, ranging from instrumentation advancement to Big Data and beyond. The project has good potential for high impact. The project aims to measure winds and temperature in the thermosphere through an acquisition of a Fabry-Perot interferometer with high sensitivity that will enable the measurements of very weak airglow emissions in the MLT region. Large thermospheric vertical winds are inconsistent with what the application of the mass continuity equation would predict using the horizontal divergence of the observed wind field. The measurements needed to resolve the discrepancy are nonexistent, thus highlighting the compelling need for advancement in the current remote sensing technologies. The observing system will yield unprecedented measurements of winds and temperatures beyond that which are currently available, leading to transformational changes in the space sciences. The added benefit is the portability of the Fabry-Perot system thus enabling collaborative studies.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

了解和预测所有空间天气活动条件下的热层风和温度对于确定卫星阻力非常重要。 本文提出的系统将产生超出目前可用的前所未有的风和温度测量结果，不仅会导致对卫星阻力的理解发生变革，而且会导致对空间科学中无数悬而未决问题的理解发生转变。 风测量具有社会意义，因为它们对于空间天气研究和全球环流模型了解和预测空间天气非常重要。 对该拟议系统中的数据进行部署、操作和分析将为本科生、研究生和研究生提供当代 STEM 主题（从仪器进步到大数据等）的机会。该项目具有产生高影响力的良好潜力。 该项目旨在通过购买一台高灵敏度的法布里-珀罗干涉仪来测量热层中的风和温度，该干涉仪将能够测量 MLT 区域非常微弱的气辉排放。 大的热层垂直风与质量连续性方程的应用利用观测到的风场的水平散度所预测的不一致。解决这一差异所需的测量并不存在，因此凸显了当前遥感技术进步的迫切需要。 该观测系统将产生前所未有的风和温度测量结果，超出目前的测量结果，从而导致空间科学的变革。 额外的好处是法布里-珀罗系统的可移植性，从而实现协作研究。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
