GEM: Self-Consistent Modeling of Inner Magnetospheric Plasma Energization and Disturbances

拟议的研究计划将通过检查粒子在现实磁场中的漂移来研究亚暴注入过程。这项研究将为亚暴期间磁层中的磁场、电流和压力的演变提供一幅自洽的图景。将对磁层规范模型进行修改，以允许边界条件随时间变化，以便能够模拟适合于亚暴中不同状态的条件，并与观测结果进行比较。电流系统对磁场结构的影响将自洽地结合在一起。还将增加其他改进措施，包括波-粒子相互作用的扩散和损失，以及粒子降水对电离层电导率的影响。

The proposed research program will study the substorm injection process by examining particle drifts in realistic magnetic fields. The study will develop a self-consistent picture of the evolution of the fields, currents, and pressures in the magnetosphere during a substorm. The Magnetosphere Specification Model will be modified to allow the boundary conditions to be varied in time so that conditions appropriate to the various states in a substorm can be simulated and compared with observations. The effects of current systems on the magnetic field structure will be incorporated self-consistently. Other refinements will also be added, including diffusion and losses due to wave-particle interactions, and the effect of particle precipitation on ionospheric conductivities.
