Collaborative Research: CEDAR: Characterization of Ionospheric-Thermospheric Long-lasting SED (Storm Enhanced Density) Dynamics

这项研究的目的是了解一种名为中纬度长期风暴增强密度(LLSED)的现象的起源和发展。LLSED是从中纬度SED羽流发出的低纬度电子密度增强的区域。术语“羽流”指的是地球磁层和电离层中的结构，它们将这两个系统连接在一起，并在其中重新分配等离子体。LLSED持续时间超过6个小时，比产生它们的SED羽流存活时间更长，并可能对通信和导航系统产生不利影响。然而，对于它们的起因仍然没有达成共识。这项工作巧妙地将地面和天基数据与数值建模工具融合在一起，以检查航空和电信行业关注的电离层干扰。这笔赠款将支持一位早期职业生涯的少数族裔科学家，并为天主教大学的REU计划做出贡献。

The goal of the research is to understand the initiation and development of a phenomenon called mid-latitude long-lasting storm enhanced density (LLSED). LLSEDs are regions of enhanced electron density at low latitudes that emanate from midlatitude SED plumes. The term "plume" refers to structures in the Earth's magnetosphere and ionosphere that couple these two systems and redistribute plasma among them. LLSEDs last over 6 hours, outliving the SED plumes that spawn them, and can potentially adversely impact communication and navigation systems. However, there remains no consensus on their causes. The work skillfully fuses ground- and space-based data with numerical modeling tools to examine ionospheric disturbances that are of some concern for the aviation and telecommunication industries. The grant will support an early career minority scientist, and contribute to Catholic U's REU program.
