Multi-Point Magnetospheric Studies

该项目是研究重点结合磁层亚暴现象的多点观测数据分析和涉及等离子体不稳定性的亚暴发生机制的理论发展的继续。分析将集中于使用来自地面阵列、ISTP卫星套件以及其他不在ISTP计划中的卫星（如DMSP）的数据来隔离亚暴。重点分析在膨胀阶段磁场能量向粒子动能的转换，以及在地面和空间观测到的事件的时空关系。研究结果将用于评估各种亚暴模型，并指导扩展开始机制的理论发展。

The project is a continuation of research focused on a combination of data-analysis using multi-point observations of magnetospheric substorm phenomena and theoretical development of a substorm onset mechanism involving plasma instabilities. Analysis will focus on isolated substorms using data from the ground based arrays, the suite of ISTP satellites as well as others not in the ISTP program such as DMSP. The analysis will focus on the conversion of magnetic field energy to particle kinetic energy during the expansion phase and the temporal and spatial relations of events observed on the ground and in space. Results will be utilized to evaluate various substorm models and to guide the theoretical development of the expansion onset mechanism.
