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被称为中纬度持久风暴增强密度（LLSED）的现象的产生和发展。llsed是低纬度地区由中纬度SED羽流发射的电子密度增强的区域。“羽流”一词指的是地球磁层和电离层中的结构，它们将这两个系统耦合起来，并在它们之间重新分配等离子体。llsed持续时间超过6小时，比产生它们的SED羽流还要长，并可能对通信和导航系统产生不利影响。然而，对其原因仍未达成共识。这项工作巧妙地将地面和天基数据与数值模拟工具融合在一起，以检查航空和电信工业所关注的电离层扰动。这笔拨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项目做出贡献。

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.
