GEM: Stormtime Magnetospheric Electric Fields: Data Analysis, Assimilation, and Modeling

了解磁层中的电场模式（对流模式）对于理解磁层内粒子和能量的流动是必不可少的。许多模型可用于正常条件，但目前还没有模型可以描述磁暴期间的磁层电场。该项目将利用DMSP卫星的电场测量数据，结合Ae指数，生成一个基于Ae指数和风暴阶段参数化的风暴时间电场模型。结果将与AMIE模拟和雷达观测结果进行比较。

A knowledge of the electric field pattern (convection pattern) in the magnetosphere is essential to and understanding of the flow of particles and energy within the magnetosphere. Many models are available for normal conditions, but no models are currently available that describe the magnetospheric electric field during magnetic storms. This project will utilize electric field measurements from the DMSP satellite in conjunction with the Ae index to produce a storm-time electric field model parameterized on the Ae index and storm phase. Results will be compared with AMIE modeling and radar observations.
