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.

该提案要求支持继续运行由四个搜索线圈磁力计（感应天线）组成的密集阵列并分析其数据，该阵列于2006年9月开始安装在挪威斯瓦尔巴特群岛，用于研究地球上的超低频波和相关现象。的空间环境。除了感应线圈磁力仪外，斯瓦尔巴特群岛上的仪器还包括许多极光成像仪和光度计，包括EISCAT，SPARG和SuperDARN在内的多个雷达，以及IMAGE阵列中最北端的磁通门磁力仪。这样一套完整的仪器使观测中的各种特征与特定磁层区域，如等离子体片、低纬度边界层、尖点或等离子体地幔相关联，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为0.02 - 5 Hz的磁场波动。该项目是空间科学界为更好地了解地球动力学而开展的国际努力的一部分。的磁层及其与太阳风和IMF的相互作用。
