项目摘要
Funds are provided to support the construction and installation of a closely-spaced array of four search coil magnetometers (induction antennas) on Svalbard for studies of Earth's space environment. The Svalbard archipelago is already the site of numerous optical sensors and auroral imagers, multiple radars including EISCAT and SuperDARN, and is the location of the northernmost stations in the IMAGE array of fluxgate magnetometers. This extensive array of instrumentation has been installed on Svalbard primarily because it is the only readily accessible site in the northern hemisphere at which the ionospheric footpoint of the magnetospheric cusp is consistently in darkness during the winter solstice. Magnetic field lines from the cusp region map to the outer boundary of Earth's magnetosphere, where it interacts with the solar wind and interplanetary magnetic field. Because of this, ground stations located under the cusp region can provide information about the first entry of energy and momentum from the solar wind to Earth's ionosphere. There is currently no search coil magnetometer array on Svalbard, however. Deployment of a closely-spaced two-dimensional array of search coil instruments, each with accurate GPS timing, will allow the PIs to determine phase differences between signals observed at different sites, and hence determine apparent propagation directions and infer wave source locations. In addition, the presence of a rich array of other instrumentation at several sites on Svalbard, especially under winter dark conditions, can provide detailed information on ionospheric regions that is not available at any other cusp latitude site. This study will contribute to our understanding of, and ability to predict, space weather phenomena that can cause power outages and increase pipeline corrosion, produce radiation damage to satellites, and create problems in radio communications, amongst other problems.
提供资金支助在斯瓦尔巴群岛建造和安装由四个搜索线圈磁力计(感应天线)组成的紧密排列阵列,用于研究地球的空间环境。斯瓦尔巴群岛已经拥有许多光学传感器和极光成像仪,包括EISCAT和SuperDARN在内的多个雷达,并且是IMAGE磁通门磁力计阵列中最北端的站点。之所以在斯瓦尔巴群岛安装这么多的仪器,主要是因为它是北半球唯一一个在冬至期间磁层尖端的电离层足点始终处于黑暗中的容易到达的地点。磁力线从尖端区域映射到地球磁层的外边界,在那里它与太阳风和行星际磁场相互作用。正因为如此,位于尖端区域下方的地面站可以提供有关太阳风首次进入地球电离层的能量和动量的信息。然而,目前在斯瓦尔巴群岛上还没有搜索线圈磁力计阵列。部署一个紧密间隔的二维搜索线圈阵列仪器,每个仪器都有精确的GPS定时,将使pi能够确定在不同地点观测到的信号之间的相位差,从而确定表观传播方向并推断波源位置。此外,在斯瓦尔巴群岛的几个地点,特别是在冬季黑暗的条件下,存在丰富的其他仪器阵列,可以提供电离层区域的详细信息,这在任何其他尖端纬度地点都是无法获得的。这项研究将有助于我们理解和预测空间天气现象,这些现象可能导致停电,增加管道腐蚀,对卫星产生辐射损伤,并在无线电通信中产生问题,以及其他问题。
