This award is funded in whole or part under the American Rescue Plan Act of 2021 (Public Law 117-2). The Geospace environment comprises a complex system of the incoming solar wind plasma flow interacting with the Earth's magnetic field and transferring its energy and momentum into the magnetosphere. This interaction takes place mainly on the Earth's dayside, where reconnecting geomagnetic field line might be "open" and directly connected to the interplanetary magnetic field lines, thus providing direct pathways for the solar wind energy to be transferred down to the ionosphere and upper atmosphere. The spatial extent of the polar cap areas controlled by the ionospheric plasma convection demarcate the so-called "Open-Closed Boundary" where solar wind particles reach down polar ionospheres. Observations of that boundary serve the important role in validating geomagnetic field modeling and help studying space weather. Motivated by the compelling Geospace research in the polar regions, this award will allow scientists to investigate magnetosphere-ionosphere coupling processes and ionospheric irregularities inside the polar caps and their space weather impacts by establishing a new ground-based network that will be deployed in the Antarctic polar cap region. This will be achieved using three new instrumented platforms (next generation of Automatic Geophysical Observatories) along the snow traverse route from the Korean Antarctic Station Jang Bogo toward to the Concordia Station at Dome C by the Korea Polar Research Institute's (KOPRI) team. Geospace data collected by these three platforms will be shared by the U.S. and Korean researchers, as well as will be made available to other scientists. The research involves early-career researchers, as well as train students who will build and operate remote Antarctic platforms, as well as analyze collected data to investigate space weather events and validate models. This project expands the U.S. institutions partnership with the KOPRI scientists and logistical support personnel.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项是根据2021年《美国救援计划法》的全部或部分资助（公法117-2）。地理环境包括一个复杂的系统，即传入的太阳风等离子体流动与地球磁场相互作用，并将其能量和动量转移到磁层中。这种相互作用主要发生在地球时代，在那里，重新连接地磁磁场线可能是“开放的”，并直接连接到行星际磁场线，从而提供了直接的途径，以使太阳能能量转移到电离层和上层大气上。由电离层血浆对流控制的极性盖面积的空间范围划定了所谓的“开放式边界”，在该边界上太阳风颗粒沿极性ion圈降落。该边界的观察在验证地磁田间建模并帮助研究空间天气方面起着重要作用。由极地地区引人入胜的地图平方研究的激励，该奖项将允许科学家调查极性帽内部的磁层 - 离子层耦合过程和电离层不规则性，以及它们的空间天气通过建立一个新的基于地面的网络，该网络将部署在南极中极盖区域。这将使用三个新的仪器平台（下一代自动地球物理观测站）沿雪地路线，从韩国南极车站Jang Bogo到韩国极地研究学院（KOPRI）团队在Dome C的Concordia站。这三个平台收集的地理数据将由美国和韩国研究人员共享，并将提供给其他科学家。该研究涉及早期研究人员以及将建立和操作远程南极平台的培训学生，以及分析收集的数据以调查太空天气事件并验证模型。该项目扩大了美国机构与Kopri科学家和后勤支持人员的合作关系。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的评估标准通过评估来获得支持的。
