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.

该项目包括两项活动。第一个项目将继续进行尖点和裂缝研究磁强计阵列观测的操作和数据分发。第二个是一个研究方案，利用MACCS数据沿着SuperDARN雷达、Resolute湾可重新定位大气观测站、南极名义上的共轭站和MACCS两个站点的全球定位系统TEC接收器。AMPERE卫星的数据也将被使用。* 利用多仪器地面和卫星数据，对昼侧高纬度超低频波和瞬变事件进行详细研究。* 为最近发射的“辐射带风暴探测器”使命提供观测和理论支持，调查超低频波在磁暴期间激发或消耗辐射带电子方面的作用，部分使用最近开发的超低频指数。* 利用磁场和GPS TEC数据沿着AMPERE项目的全球数据，调查与瞬变事件和稳定对流有关的高纬度场向电流结构。* 利用MACCS数据与来自低轨道和高轨道卫星的同步数据相结合，将磁层和电离层过程的空间和时间变化分开，并对超低频波通过全球磁层-电离层系统的激发和传播进行理论和模拟研究。本研究将使用BATS-R-US全球磁流体动力学模拟程序。MAACS数据免费分发给整个科学界。
