This project addresses electrodynamic processes in the Earth's ionosphere at low and mid-latitudes. These processes will be studied simultaneously in both hemispheres in the American sector from locations along the same geomagnetic field lines. Data from ground-based all-sky imagers and in-situ satellite measurements will be analyzed. The results of this study will be made broadly available, will help to understand how inter-hemispheric coupling occurs, and can be incorporated in global scale models of ionospheric electrodynamics, which are relevant to understanding Space Weather. This research will involve graduate and undergraduate students. Specifically, this project will investigate the behavior of ionospheric perturbations related to equatorial Spread-F (ESF) and medium-scale traveling ionospheric disturbances (MSTIDs). Observations include all-sky imagers and Fabry-Perot interferometers at magnetically conjugate locations in the American Sector. The generation mechanism of MSTIDs will be investigated using the conjugate measurements as well as data from the C/NOFS satellite.

该项目研究低纬度和中纬度地球电离层的电动力过程。这些过程将在美国区域的两个半球沿相同地磁场线的位置同时进行研究。来自地面全天成像仪和现场卫星测量的数据将被分析。 这项研究的结果将广泛公开，将有助于了解半球间耦合是如何发生的，并且可以纳入电离层电动力学的全球尺度模型中，这与理解空间天气相关。这项研究将涉及研究生和本科生。 具体来说，该项目将研究与赤道 Spread-F (ESF) 和中等尺度行进电离层扰动 (MSTID) 相关的电离层扰动行为。观测包括位于美国扇区磁共轭位置的全天空成像仪和法布里-珀罗干涉仪。将使用共轭测量以及来自 C/NOFS 卫星的数据来研究 MSTID 的生成机制。
