Collaborative Research: Studies of Solar Wind - Magnetosphere Interactions using Observations of ULF Waves at an Extensive Ground Array at High Latitudes

有了这个奖项，来自美国三家机构的研究人员将专注于探索和了解近地？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，来改善美国空间环境（地球空间）。因为地球的那些部分？由于地球空间的磁场在高纬度地区与地面相交，地面磁力计阵列和极光成像仪长期以来一直是监测磁层偏远地区过程的重要手段。本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。这些仪器与设在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相结合，在研究包括太阳风在内的地球空间现象方面已经并将继续发挥重要作用。磁层相互作用与地磁风暴和亚风暴。总的来说，这些站点的搜索线圈仪器可以研究整个范围的超低频率（ULF）变化，从pc1和Pi 1脉动到pc5脉动，磁脉冲事件，突然脉冲和亚风暴湾，具有高灵敏度。与此项目相关的分析工作将涉及并非常适合本科生和研究生的研究训练，并建立在目前强大的教师和学生研究项目的基础上。

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.
