CEDAR: Conjugate Studies of Low and Midlatitude Ionospheric Processes

该项目涉及中低纬度地区地球电离层中的电动力学过程。这些过程将在沿相同地磁力线的美国地区的两个半球同时进行研究。将分析来自地面全天成像仪和现场卫星测量的数据。这项研究的结果将被广泛提供，将有助于理解半球间耦合是如何发生的，并可纳入与理解空间天气有关的全球尺度的电离层电动力学模型。这项研究将涉及研究生和本科生。具体地说，该项目将调查与赤道扩展F(ESF)和中等尺度行进电离层扰动(MSTID)有关的电离层扰动的行为。观测包括全天空成像仪和法布里-珀罗涉仪，它们位于美国地区的磁性共轭位置。将利用共轭测量以及来自C/NOFS卫星的数据来研究MSTID的产生机制。

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.
