This CAREER grant will study the upper atmosphere and magnetosphere-ionosphere-thermosphere (MIT) coupling at high latitudes. The polar upper atmosphere is a complex region driven by wave disturbances generated in the lower atmosphere and by the energy fed through the magnetosphere. The research work will advance our understanding of the variability of the polar upper atmosphere region by novel applications of lidar and radar observations, and computational models. This CAREER grant will integrate research and education by developing a new curriculum in atmospheric modeling, giving students an early exposure to current research topics in atmospheric research and high-performance computing. The grant will also support integration of research and education to develop a knowledgeable STEM workforce. The outreach activities will actively pursue efforts to broaden participation amongst members of underrepresented groups and develop a diverse scientific workforce that is reflective of our society. The overall goal of this CAREER grant is to study atmospheric wave dynamics and magnetosphere-ionosphere-thermosphere (MIT) coupling in the polar regions using observations and computational models. The research will investigate the following key aspects of the polar aeronomy: 1) the dynamics, coupling, and interactions of polar atmospheric waves; 2) the localized magnetospheric energy deposition and MIT coupling at high latitudes; and 3) the interactions and comparative contributions of the lower atmosphere wave forcing and magnetospheric forcing to the variability of geospace.Results from this research will advance our understanding of the role wave-wave and wave-mean interactions, intra-hemispheric coupling, and inter-hemispheric asymmetries on the polar upper atmosphere. The research will also lead to improvement in computational models used to upper atmospheric research.The research also includes a major educational development component. The educational activities will: 1) develop a new curriculum for atmospheric modeling and create an inventory of numerical programs that will be used for both education and research, and develop and publicize an education website to host this inventory for highly interactive model runs and learning; 2) mentor graduate and undergraduate students with interdisciplinary knowledge and solid skills, and provide research opportunities for underrepresented students via the Call Me Mister program; and3) involve high school students and K-12 teachers from South Carolina rural communities in atmospheric science education via Clemson's Emerging Scholar and outreach programs.This career grant will provide education and training opportunities for the next generation of STEM workforce and implement activities for broadening participation and the development of a diverse scientific workforce.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.

这项CAREER基金将研究高纬度地区的高层大气和磁层-电离层-热层（MIT）耦合。极地高层大气是一个复杂的区域，由低层大气产生的波扰动和通过磁层提供的能量驱动。这项研究工作将通过激光雷达和雷达观测的新应用以及计算模型，促进我们对极地高层大气区域变化的理解。这项职业补助金将通过开发大气建模的新课程来整合研究和教育，使学生尽早接触到大气研究和高性能计算的当前研究课题。该拨款还将支持研究和教育的整合，以培养一支知识渊博的STEM劳动力队伍。外联活动将积极努力扩大代表性不足群体成员的参与，并发展一支反映我们社会的多样化科学队伍。这项CAREER资助的总体目标是利用观测和计算模型研究极地地区的大气波动动力学和磁层-电离层-热层（MIT）耦合。本研究将从以下几个方面探讨极地航空学的关键问题：1)极地大气波的动力学、耦合和相互作用；2)高纬度地区局部磁层能量沉积与MIT耦合；低层大气波强迫和磁层强迫对地球空间变率的相互作用及其比较贡献。本研究结果将促进我们对波-波和波-平均相互作用、半球内耦合和半球间不对称在极地高层大气中的作用的理解。这项研究还将改进用于高层大气研究的计算模型。这项研究还包括一个主要的教育发展组成部分。教育活动将：1)开发一个新的大气建模课程，并创建一个将用于教育和研究的数值程序清单，并开发和宣传一个教育网站，以托管这个清单，用于高度互动的模型运行和学习；2)为研究生和本科生提供跨学科知识和扎实技能的指导，并通过Call Me Mister项目为代表性不足的学生提供研究机会；3)通过克莱姆森的新兴学者和推广项目，让南卡罗来纳州农村社区的高中生和K-12教师参与大气科学教育。这项职业补助金将为下一代STEM工作人员提供教育和培训机会，并开展活动，以扩大参与和发展多元化的科学工作人员。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
