The two most significant periods when magnetospheric energy is transported from one region to another and shifted from magnetic fields to particles are during magnetic storms and substorms. In particular, during storms and substorms a substantial portion of the energy to converted into the high-energy portion of the particle distributions. This research program will use theoretical techniques and numerical test particle tracing techniques to examine how the energization of particles takes place and how the energetic particles are transported within the magnetosphere. The ultimate goal is to produce a predictive model of energetic particle injection during storms and substorms. This model could then be used in the construction of the GGCM.

磁暴和亚暴是磁层能量从一个区域转移到另一个区域以及从磁场转移到粒子的两个最重要的时期。 特别是，在风暴和亚暴期间，相当大一部分能量被转换成粒子分布的高能部分。 这项研究计划将使用理论技术和数值测试粒子追踪技术来研究粒子的碰撞是如何发生的，以及高能粒子是如何在磁层内传输的。 最终的目标是产生一个预测模型的高能粒子注入风暴和亚暴。 然后，该模型可用于GGCM的构建。
