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

这项提议要求支持继续运行和分析由四个搜索线圈磁力仪(感应天线)组成的近距离阵列的数据，该阵列于2006年9月开始在挪威斯瓦尔巴特群岛安装，用于研究地球-S空间环境中的超低频波及相关现象。除了感应线圈磁强计外，斯瓦尔巴群岛上的仪器还包括许多极光成像仪和测光仪、包括EISCAT、SPEAR和SuperDARN在内的多个雷达，以及磁通门磁强计图像阵列中最北端的站。这样一套完整的仪器使观测中的各种特征能够与特定的磁层区域相联系，例如等离子体片、低纬边界层、尖点本身或等离子体地幔，比在其他地点的早期研究更有信心和可靠性。感应线圈磁强计的作用是检测0.02-5赫兹频率范围内的磁波动。该项目是空间科学界国际努力的一部分，目的是更好地了解地球--S磁层的动力学及其与太阳风和国际货币基金组织的相互作用。

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.
