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.

该项目以低和中纬度的方式解决了地球电离层中的电动力过程。这些过程将在美国部门的两个半球中同时研究，沿着相同的地磁磁场线。将分析来自地面的全基成像仪和原位卫星测量结果的数据。 这项研究的结果将广泛可用，将有助于了解半球间耦合的发生方式，并可以将与理解空间天气有关的电离层电动力学模型纳入全球尺度模型。这项研究将涉及研究生和本科生。 具体而言，该项目将研究与赤道扩散-F（ESF）和中尺度行进电离层扰动（MSTIDS）有关的电离层扰动的行为。观察结果包括在美国部门的磁性共轭位置上的全天空成像仪和Fabry-Perot干涉仪。将使用C/NOFS卫星的数据研究MSTID的生成机制。
