Collaborative Research: Continued study of ULF waves at cusp latitudes on Svalbard to probe Earth's space environment

该提案要求支持由四个搜索线圈磁力计（感应天线）组成的密集阵列的持续运行和数据分析，该阵列于 2006 年 9 月开始在挪威斯瓦尔巴群岛安装，用于研究地球空间环境中的 ULF 波和相关现象。除了感应线圈磁力计之外，斯瓦尔巴群岛上的仪器还包括许多极光成像仪和光度计、包括 EISCAT、SPEAR 和 SuperDARN 在内的多种雷达，以及磁通门磁力计 IMAGE 阵列中最北端的站。这样一整套仪器能够将观测中的各种特征与特定磁层区域（例如等离子体片、低纬边界层、尖点或等离子体地幔）关联起来，比其他地点的早期研究更有信心和可靠性。感应线圈磁力计的作用是检测频率范围 0.02 - 5 Hz 内的磁波动。该项目是空间科学界为更好地了解地球磁层动态及其与太阳风和国际货币基金组织相互作用而开展的国际努力的一部分。

This proposal requests support for the continued operation of, and analysis of data from, a closely-spaced array of four search coil magnetometers (induction antennas) the installation of which began in September 2006 on Svalbard, Norway, for studies of ULF waves and associated phenomena in Earth?s space environment. In addition to induction coil magnetometers, instruments on Svalbard include numerous auroral imagers and photometers, multiple radars including EISCAT, SPEAR, and SuperDARN, and the northernmost stations in the IMAGE array of fluxgate magnetometers. Such a complete suite of instruments enables the association of various features in the observations with specific magnetospheric regions, such as the plasma sheet, low latitude boundary layer, cusp proper, or plasma mantle, with more confidence and reliability than in earlier studies at other locations. The role of induction coil magnetometers is to detect magnetic fluctuations in the frequency range 0.02 - 5 Hz. This project is part of an international effort by the space science community to better understand the dynamics of Earth?s magnetosphere and of its interaction with the solar wind and IMF.
