Satellite Magnetic Field Data Analysis: Magnetospheric/Ionospheric Currents and Waves

调查人员将继续分析由卫星磁强计获得的磁场观测数据。这项工作是一个综合的团队方法，以推进对场向电流、磁层和电离层电流、电磁波和湍流的理解。该小组将研究与场向电流相关的两个不同的研究课题：沿着卫星轨道比较预测和测量的磁场扰动，以及研究磁层中磁流体动力快模波驱动源的相对重要性。第一项研究将使用超级雷达网络和AMIE数值模型的测量结果。第二项研究将利用来自AMPTE、CRRES和GOES卫星的多点观测。

The investigators will continue analysis of magnetic field observations acquired by satellite-borne magnetometers. The effort is an integrated team approach to advance understanding of field-aligned currents, magnetospheric and ionospheric currents, and electromagnetic waves and turbulence. The group will investigate two different research topics related to field-aligned currents: comparing predicted to measured magnetic field perturbations along a satellite orbit, and studying the relative importance of driving sources for magnetohydrodynamic fast mode waves in the magnetosphere. The first study will use measurements by the SuperDARN radar network and the AMIE numerical model. The second study will make use of multi-point observations from the AMPTE, CRRES and GOES satellites.
