This project continues research efforts on the morphology and dynamics of the Earth's magnetosphere. The methodology emphasizes particle precipitation data and auroral imagery from low altitude satellites. Ionospheric convection as determined from HF radars as well as middle-magnetosphere satellite data will also play crucial roles in the program. Research will be conducted in four broad categories. The first category concerns the low-altitude signatures of magnetopause processes in which we will clarify the distinctions between various high altitude magnetospheric plasma regimes. The second category addresses dayside auroral phenomenology using coordinated satellite imagery and particle precipitation data, particularly from the DMSP satellites. The third category involves coordinated observations using the extensive DMSP satellite data and ground-based coherent radar data to investigate the dynamics of substorm behavior. Finally, the fourth category involves magnetic field-aligned processes that connect the low altitude regions to the middle magnetosphere.

该项目继续对地球磁层的形态和动态进行研究。 该方法强调粒子降水数据和来自低空卫星的极光图像。 由高频雷达和中磁层卫星数据确定的电离层对流也将在该计划中发挥关键作用。 研究将在四大类中进行。 第一类涉及磁层顶过程的低空特征，我们将在其中澄清各种高空磁层等离子体制度之间的区别。 第二类利用协调的卫星图像和粒子降水数据，特别是来自DMSP卫星的数据，研究昼侧极光现象。 第三类是利用广泛的DMSP卫星数据和地面相干雷达数据进行协调观测，以调查亚暴行为的动力学。 最后，第四类涉及磁场对齐的过程，连接低海拔地区的中间磁层。
