CEDAR: Global and Local Measurements of Lightning-Mesosphere Interactions

该项目将综合利用空间和地面数据来描述闪电电流与瞬态发光事件之间的关系，瞬态发光事件是对流层和高层大气之间向上能量耦合的直观表现。 具体而言，该项目将利用高时间分辨率光学和电磁测量对TLE观测进行详细的事件级分析，以评估TLE内部结构和动力学对中间层状态参数的影响。 此外，卫星光学数据将与地面电磁测量网络结合使用，以获得对流层热释光源和中间层相关响应的全球测绘。 这项工作的目标是提供一个基础，以评估可能的本地，区域和全球影响的TLE在高层大气中，并提供更好的规范的背景电磁环境，他们发起和传播。 这项工作将支持研究生的教育和研究培训，并涉及本科生的研究参与。

This project is to utilize a combination of space- and ground-based data to characterize the relationship between lightning current and transient luminous events (TLEs), which are the visual manifestation of upward energy coupling between the troposphere and upper atmosphere. Specifically, this project will conduct detailed, event-level analysis of TLE observations using high time resolution optical and electromagnetic measurements in order to assess the effects of internal TLE structure and dynamics on mesospheric state parameters. In addition, satellite optical data will be used in conjunction with a network of ground-based electromagnetic measurements to obtain a global mapping of tropospheric sources of TLEs and associated responses in the mesosphere. The goal of this effort is to provide a foundation for evaluating possible local, regional, and global effects of TLEs in the upper atmosphere and to provide better specification of the background electromagnetic environment where they initiate and propagate. This work will support the education and research training of a graduate student as well as involve research participation by undergraduates.
