Collaborative Research: PENGUIn - A High-Latitude Window to Geospace Dynamics

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。PENGUIn小组将继续深入调查一个多尺度电动系统，该系统包括地球空间环境。该建议概述了对空间物理学和高层大气学具有重要意义的几个科学专题，这些专题可大致分为以下几类：（a）研究南尖区的重联和波;（B）调查正在解开的全球地磁亚暴特征;（c）了解昼侧波粒相互作用;（d）观测和调查各种极冠现象和中性大气动态。将通过从南极洲自主观测站分布式网络获取多仪器数据来完成这些关键主题的尖端科学，这些观测站是利用成熟的技术成就建立和部署的。在过去的几年里，自动地球物理观测站（AGO）的供电系统和铱数据传输的进步已被证明是有效的，可靠地提供实时地球物理数据。从极光区到极冠深处的五个AGO将被保留，为科学分析提供丰富的数据。将在AGO部署其他仪器，如测量电离层总电子含量的GPS接收器。南极载人站、北极磁共轭区以及一组磁层和电离层航天器进行的补充测量将丰富这些科学调查。对学生的持续依赖为这项拟议的研究提供了更广泛的影响，并在其教育使命中坚定地支持这项努力。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The PENGUIn team will continue investigating in depth a multi-scale electrodynamic system that comprises space environment of Planet Earth (geospace). Several science topics important to the space physics and aeronomy are outlines in this proposal that can be broadly categorized as the following objectives: (a) to study reconnection and waves in the southern cusp region; (b) to investigate unraveling global geomagnetic substorm signatures; (c) to understand the dayside wave-particle interactions; and (d) to observe and investigate various polar cap phenomena and neutral atmosphere dynamics. Cutting-edge science on these critical topics will be accomplished by acquiring multi-instrument data from a distributed network of autonomous observatories in Antarctica, built and deployed with the matured technological achievements. In the last several years, advances in power supply systems and Iridium data transmission for the Automatic Geophysical Observatories (AGOs) have proven effective for providing real-time geophysical data reliably. Five AGOs that span from the auroral zone to deep in the polar cap will be maintained providing a wealth of data for science analyses. Additional instrumentation as GPS-based receivers measuring total electron content in the ionosphere will be deployed at AGOs. These scientific investigations will be enriched by complementary measurements from manned stations in the Antarctic, from magnetically conjugate regions in the Arctic, and from a fleet of magnetospheric and ionospheric spacecraft. Continued reliance on students provides a broader impact to this proposed research and firmly grounds this effort in its educational mission.
