This project will utilize both VHF radio and a network of GPS sensor data collected in the southern (Western Australia) hemisphere, in a collaboration between the US, Australia, and India, to improve the understanding of the storm-time response of the mid-latitude ionosphere. The observations will be obtained in a longitude sector which has a large offset between geographical and geomagnetic sectors, thought to be important for storm-enhanced plasma density (SED) plume generation, and which is similar to that in the northern hemisphere where the proposers have conducted such investigations in the past. Specifically, the investigation will focus on the dynamics and evolution of SED structures, including a comparison between SED behavior in the two hemispheres, as well as on associated total electron content (TEC) gradients and generation of scintillation, which will be observed at unprecedented spatiotemporal detail. This project will provide access to data and research opportunities to students as well as support full-time post-doc involvement.

该项目将利用甚高频无线电和在南半球(西澳大利亚)收集的GPS传感器数据网络，与美国、澳大利亚和印度合作，以提高对中纬度电离层风暴时间响应的理解。观测将在地理和地磁部分之间有很大偏移量的经度部分获得，这被认为对风暴增强等离子体密度(SED)羽流的产生很重要，而且类似于提出建议的人过去在北半球进行过此类调查的地方。具体地说，研究的重点将是SED结构的动力学和演化，包括两个半球内SED行为的比较，以及相关的总电子含量(TEC)梯度和闪烁的产生，这将以前所未有的时空细节进行观察。该项目将为学生提供访问数据和研究的机会，并支持全日制博士后参与。
