This project consists of two activities. The first will continue the operation and data distribution of observations from the Magnetometer Array for Cusp and Cleft Studies (MACCS). The second is a research program using the MACCS data along with SuperDARN radar, the Relocatable Atmospheric Observatory in Resolute Bay, nominally conjugate stations in the Antarctic and GPS TEC receivers at two of the MACCS sites. Data from the AMPERE satellites also will be used. The proposal identifies four topics: * Performing detailed studies of dayside high-latitude ULF waves and transient events, using multi-instrument ground-based and satellite data. * Providing observational and theoretical support for the recently-launched Radiation Belt Storm Probes mission by investigating the role of ULF waves in energizing or depleting radiation belt electrons during magnetic storms, in part using the recently developed ULF index. * Investigating the high-latitude field-aligned current structures associated with both transient events and steady convection, using magnetic field and GPS TEC data along with global data from the AMPERE project. * Using the combination of MACCS data with simultaneous data from both low-orbiting and high-orbiting satellites to separate spatial and temporal variations in magnetospheric and ionospheric processes, and carrying out theoretical and modeling studies of the excitation and propagation of ULF waves through the global magnetosphere-ionosphere system. This study will use the BATS-R-US global magnetohydrodynamic simulation code. The MAACS data are freely distributed to the entire science community.

该项目由两项活动组成。第一个将继续用于尖端和裂缝研究的磁力计阵列（MACCS）的观测结果的操作和数据分发。第二个是使用 MACCS 数据以及 SuperDARN 雷达、Resolute Bay 的可重定位大气观测站、名义上的南极共轭站以及两个 MACCS 站点的 GPS TEC 接收器的研究计划。来自 AMPERE 卫星的数据也将被使用。该提案确定了四个主题： * 使用多仪器地面和卫星数据对白天高纬度 ULF 波和瞬变事件进行详细研究。 * 通过研究 ULF 波在磁暴期间激发或消耗辐射带电子的作用，部分使用最近开发的 ULF 指数，为最近启动的辐射带风暴探测器任务提供观测和理论支持。 * 使用磁场和 GPS TEC 数据以及来自 AMPERE 项目的全球数据，研究与瞬态事件和稳定对流相关的高纬度场对准电流结构。 * 利用MACCS数据与低轨和高轨卫星同步数据相结合，分离磁层和电离层过程的时空变化，开展全球超低频波激发和传播的理论和模型研究磁层-电离层系统。本研究将使用 BATS-R-US 全球磁流体动力学模拟代码。 MAACS 数据免费分发给整个科学界。
