This award to SRI International (Dr. Konstantinos Kalogerakis) will support the quantitative reevaluation of the mesosphere and lower thermosphere chemistry based upon new laboratory results. Nightglow emission signatures observed from space and ground-based instruments are commonly used as proxies for atmospheric composition, especially for the altitude region around 100 km that cannot be easily studied in situ. Monitoring the intensity and temporal evolution of such proxies by remote sensing is the method of choice to study many phenomena occurring in this region of the atmosphere. This award would support the quantitative reanalysis of the details relevant to the production and loss of excited atomic and molecular precursors responsible for prominent nightglow emissions. These results would quantify more precisely the study of atmospheric composition, radiative and energy balance, wave propagation and dissipation, as well as transport dynamics. One or two undergraduate students would be engaged in this work through a site REU grant awarded to SRI International.The thrust of this reevaluation to be supported by this award would be aimed at the investigation of the coupling between the OH Meinel and the O2 Atmospheric band emissions, which is connected to the collisions of O atoms with vibrationally excited OH. Part of this study would utilize observational data sets derived from multiple sounding rocket experiments that would be combined with modeling methodologies based upon recently developed efforts based upon new laboratory findings.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.

该奖项授予SRI International（Konstantinos Kalogerakis博士），将根据新的实验室结果来支持中层和降低热层化学的定量重新评估。 从空间和地面仪器中观察到的床上发射特征通常用作大气成分的代理，尤其是对于100公里约100公里的高度区域，无法轻松地进行原位研究。通过遥感监测此类代理的强度和时间演变是研究大气区域中许多现象的选择。该奖项将支持与负责突出夜总会排放的激发原子和分子前体的生产和损失有关的细节的定量重新分析。这些结果将更准确地量化大气组成，辐射和能量平衡，波传播和耗散以及运输动力学的研究。一两个本科生将通过授予SRI International授予的现场REU赠款从事这项工作。该奖项的重新评估的推力将旨在调查OH Meinel和O2大气乐队的耦合，这与O2大气乐队的排放之间的耦合，这与A Atoms与Atoms碰撞的OH ATOM相关联OH OH OH OH。这项研究的一部分将利用从多个发声的火箭实验中得出的观察数据集，这些数据集将与基于最近基于新的实验室发现的最近开发的努力相结合的建模方法。该奖项反映了NSF的法定任务，并被视为值得通过基金会的知识智能和更广泛影响的评估来通过评估来获得支持的审查审查标准。
