The Earth's magnetosphere exhibits a variety of behaviors that appear to represent distinct states of the magnetosphere. An alternative theory, however, is that these apparently disparate states are simply manifestations of a unified response of the magnetosphere to the solar wind driver. This work will clarify the situation by examining the relationship between magnetic substorms and magnetic storms and the relationship between magnetic substorms and steady magnetospheric convection (SMC). This project will examine these relationships primarily from a data analysis point of view, using data from global auroral imagers (Viking, Polar, and IMAGE satellites), neutral atom imagery (Polar and IMAGE), energetic particle measurements from the Los Alamos geosynchronous satellites and grand-based auroral and magnetic data.

地球的磁层表现出各种各样的行为，似乎代表了磁层的不同状态。 然而，另一种理论认为，这些明显不同的状态只是磁层对太阳风驱动器的统一响应的表现。 这项工作将通过研究磁亚暴和磁暴之间的关系以及磁亚暴和稳定磁层对流（SMC）之间的关系来澄清这种情况。 该项目将主要从数据分析的角度审查这些关系，使用来自全球极光成像仪（维京海盗、Polar和IMAGE卫星）的数据、中性原子图像（Polar和IMAGE）、来自洛斯阿拉莫斯地球同步卫星的高能粒子测量数据以及基于grand的极光和磁力数据。
