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。企鹅号团队将继续深入研究包含地球空间环境（地球空间）的多尺度电动力系统。本提案概述了几个对空间物理学和航空学很重要的科学课题，可大致归类为以下目标：(a)研究南尖端地区的重联和波；(b)研究解开全球地磁亚暴的特征；(c)了解日侧波粒相互作用；(d)观测和研究各种极帽现象和中性大气动力学。这些关键主题的前沿科学将通过从南极自主观测站的分布式网络获取多仪器数据来完成，该网络将利用成熟的技术成果建立和部署。在过去的几年里，自动地球物理观测站（AGOs）的供电系统和铱星数据传输的进步已经被证明是可靠地提供实时地球物理数据的有效手段。从极光区到极帽深处的5个古带将保持不变，为科学分析提供丰富的数据。额外的仪器，如基于gps的接收器，测量电离层中的总电子含量，将部署在AGOs。南极载人站、北极磁共轭区以及磁层和电离层航天器舰队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，并坚定地将这一努力作为其教育使命的基础。

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.
