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

了解磁层中的电场模式(对流模式)对于了解磁层内的粒子和能量流动是必不可少的。在正常情况下有许多模型可用，但目前还没有描述磁暴期间磁层电场的模型。该项目将利用DMSP卫星的电场测量，结合Ae指数，制作一个风暴时间电场模型，该模型以Ae指数和风暴阶段为参数。结果将与AMIE模型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.
