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.

在空间天气活动的所有条件下，了解和预测热圈风和温度对于确定卫星阻力很重要。 本文提出的系统将对当前可用的风和温度进行前所未有的测量，从而导致对不仅卫星阻力的理解，而且导致太空科学中无数的出色问题的变革变化。 风测量值具有社会意义，因为它们对于太空天气研究和全球循环模型很重要，以了解和预测太空天气。 该拟议系统数据的部署，操作和分析将使本科，研究生和研究生的当代STEM主题的机会，从仪器的进步到大数据及以后。该项目具有高影响力的潜力。 该项目旨在通过获得高灵敏度的Fabry-Perot干涉仪的采集来测量热层中的风和温度，这将使MLT区域中非常弱的气流排放的测量值。 大型热层垂直风与使用观察到的风场的水平差异预测的质量连续性方程的应用不一致。解决差异所需的测量是不存在的，因此突出了当前遥感技术的迫切需求。 观测系统将对当前可用的风和温度进行前所未有的测量，从而导致太空科学的变化变化。 额外的好处是Fabry-Perot系统的可移植性，从而实现了协作研究。该奖项反映了NSF的法定任务，并且使用基金会的知识分子优点和更广泛的影响评估标准，被认为值得通过评估来获得支持。
