With this award, researchers from three U.S. institutions will focus on exploring and understanding near-Earth?s space environment (geospace) through the coordinated use of multiple data sets, including both a variety of individual spacecraft and strategically located ground observatories. Because those parts of the Earth?s magnetic field that reach farthest out into geospace intersect the ground at high latitudes, arrays of ground magnetometers and auroral imagers have long been a valued means of monitoring processes in remote parts of the magnetosphere. The ground stations used in this project are key links in arrays of ground-based ionospheric and magnetospheric observations in both the Arctic and Antarctic regions. In conjunction with data from other instruments located at these sites, with other Antarctic arrays of automated instruments, and with both low-altitude and high-altitude satellites, these instruments have played and will continue to play a significant role in the studies of geospace phenomena including solar wind?magnetosphere interactions and geomagnetic storms and substorms. Taken together, search coil instruments at these stations make it possible to study the entire range of ultra-low frequency (ULF) variations, from Pc 1 and Pi 1 pulsations down to Pc 5 pulsations, magnetic impulse events, sudden impulses, and substorm bays, with high sensitivity. The analysis efforts associated with this project will involve, and are highly suitable for, research training of both undergraduate and graduate students, and build on currently strong programs of faculty and student research.

获得该奖项后，来自三个美国机构的研究人员将通过协调使用多个数据集（包括各种单独的航天器和战略位置的地面观测站）来专注于探索和了解近地空间环境（地球空间）。由于地球磁场最远延伸到地球空间的部分在高纬度与地面相交，地面磁力计和极光成像仪阵列长期以来一直是监测磁层偏远部分过程的重要手段。该项目使用的地面站是北极和南极地区地面电离层和磁层观测阵列的关键环节。结合来自这些地点的其他仪器、其他南极自动化仪器阵列以及低空和高空卫星的数据，这些仪器已经并将继续在地球空间现象的研究中发挥重要作用包括太阳风、磁层相互作用以及地磁风暴和亚暴。总而言之，这些站的探测线圈仪器可以研究超低频 (ULF) 变化的整个范围，从 Pc 1 和 Pi 1 脉动到 Pc 5 脉动、磁脉冲事件、突发脉冲和亚暴湾，具有高灵敏度。与该项目相关的分析工作将涉及并且非常适合本科生和研究生的研究培训，并建立在当前强大的教师和学生研究计划的基础上。
