Investigation of the Ionospheric Dynamics and MI Coupling in Antarctica

该提案寻求资金，以在南极南极站建造高频科学雷达，从而加强部署在世界各地的22雷达SuperDARN网络(http://superdarn.jhuapl.edu).)的研究能力南极雷达将填补南极上空极光物理研究的空白，帮助建立对南半球整个极光椭圆形的完全覆盖，并增加其他南极空间物理仪器的财富。该雷达将研究：(A)进入和离开南极极冠的太阳风等离子体以及通过极冠的电离等离子体斑块的运动；(B)全球电离层和磁层对流对太阳风和行星际磁场变化的反应；(C)磁层对太阳风突然变化以及地球磁暴和亚暴的反应；(D)等离子体斑块与中层风和热层重力波的相互作用。此外，通过扩大南半球的全球范围，可以解决全球磁暴和亚暴的地磁共轭问题，以及由于两个半球的太阳照度不对称造成的电离层等离子体对流的差异。SuperDARN网络具有以出色的时间和空间分辨率观测全球范围对流的能力，已被证明是可用于地面研究的最强大的工具，使科学家能够解决空间物理中最基本和最重要的问题。SuperDARN的国际社会为许多博士后研究员、研究生和本科生的教育做出了重大贡献，从而帮助培养了一代空间物理和航空领域的年轻研究人员。拟议的项目还将提供与空间气象研究等重要社会问题有关的数据，并加强来自其他文书的数据的实用性。

This proposal seeks funding to build the high-frequency scientific radar at the South Pole Station in Antarctica, thus enhancing research capabilities of the 22-radars SuperDARN network deployed around the world (http://superdarn.jhuapl.edu). The South Pole radar will fill a gap in the studies of auroral physics over the Antarctic, helping to establish complete coverage of the entire auroral oval in the Southern hemisphere and adding to the wealth of other Antarctic space physics instruments. This radar will be studying: (a) solar wind plasma entry into and exit from the Southern polar cap and motions of ionized plasma patches through the cap, (b) responses of the global ionospheric and magnetospheric convection to solar wind and interplanetary magnetic field changes, (c) magnetospheric responses to abrupt solar wind changes and geomagnetic storms and substorms, and (d) the plasma patches interactions with mesospheric winds and thermospheric gravity waves. In addition, by extending the global-scale coverage in the Southern hemisphere, questions about geomagnetic conjugacy of global magnetic storms and substorms and differences in the ionospheric plasma convection caused by the asymmetry of solar illumination in both hemispheres can be addressed. The SuperDARN network, with its ability to observe global-scale convection with excellent temporal and spatial resolution, has proven to be the most powerful tool available for the ground-based research, allowing scientists to address the most fundamental and important questions of space physics. The SuperDARN's international community contributed significantly to the education of many postdoctoral fellows, graduate, and undergraduate students, thus helping to grow a generation of young researchers in the field of space physics and aeronomy. The proposed project will also provide data relevant to important societal issues such as space weather studies and enhance the usefulness of data from other instruments.
