项目摘要

This award would continue the operations of the Magnetometer Array for Cusp and Cleft Studies (MACCS) network combined with the dissemination of its data and the scientific analysis of MACCS data in collaboration with other ground-based and space-based research teams. MACCS is a longitudinal array of high latitude fluxgate magnetometers covering the Eastern Canadian Arctic at high latitudes(75-85N), providing continuity of spatial coverage between existing Canadian and Greenland arrays. MACCS has contributed to the study of ULF waves and transients at these extreme latitudes as well as large cooperative studies of magnetosphere-ionosphere coupling, ionospheric convection, and magnetic storm and substorm processes. The combination of the location of several MACCS stations under the field of view of the SuperDARN / PolarDARN radar network, their proximity to the field of view of the AMISR radar system at Resolute Bay, Canada, and the nominal "conjugacy" of four MACCS stations with U. S. Antarctic stations as well as the recent addition of dual high-sampling-rate GPS TEC receivers makes possible additional comparative studies that would be quite rich in possible transformative outcomes. Each MACCS site transmits data in near real time (two through Iridium, six through the local wireless internet. The MACCS array has provided ground-based magnetic field observations that will continue to play a fundamental role in magnetospheric and ionospheric research and will continue to provide critical data for studies of various geospace phenomena including solar wind-magnetosphere and magnetosphere-ionosphere interactions, the dynamics of the high latitude polar cap regions of the magnetosphere, and geomagnetic storms and substorms. The scientific analysis of MACCS data would focus on the topics such as the detailed studies of high-latitude ULF waves, using multi-instrument ground-based and satellite data from the Van Allen Probes and SWARM and studies of the role of ULF waves in energizing or depleting radiation belt electrons during magnetic storms. Theoretical studies and modeling studies (using the Space Weather Modeling Framework) of the excitation and propagation of ULF waves through the global magnetosphere-ionosphere system, and exploring the physical mechanisms involved would be particular aspects of the science issues covered in this award.

该合同将继续用于尖端和裂隙研究的磁力计阵列（MACCS）网络的运行，并与其他地面和天基研究团队合作，传播其数据以及对 MACCS 数据进行科学分析。 MACCS是一个纵向阵列的高纬度磁通门磁力计，覆盖加拿大东部北极地区的高纬度（75-85N），提供现有加拿大和格陵兰阵列之间空间覆盖的连续性。 MACCS 为这些极端纬度的 ULF 波和瞬变的研究以及磁层-电离层耦合、电离层对流以及磁暴和亚暴过程的大型合作研究做出了贡献。 SuperDARN / PolarDARN 雷达网络视场下的几个 MACCS 站的位置、它们与加拿大雷索卢特湾 AMISR 雷达系统视场的接近程度以及四个 MACCS 站的名义“共轭”的组合与美国南极站的合作以及最近添加的双高采样率 GPS TEC 接收器使得额外的比较研究成为可能，这些研究将产生非常丰富的可能的变革结果。每个 MACCS 站点都近乎实时地传输数据（两个通过铱星，六个通过本地无线互联网）。MACCS 阵列提供了地面磁场观测，这些观测将继续在磁层和电离层研究中发挥基础作用，并将继续提供研究各种地球空间现象的关键数据，包括太阳风-磁层和磁层-电离层相互作用、磁层高纬度极冠区域的动力学以及地磁风暴和亚暴的科学分析。 MACCS 数据的重点是使用来自范艾伦探测器和 SWARM 的多仪器地面和卫星数据对高纬度 ULF 波进行详细研究，以及 ULF 波在激发或消耗辐射中的作用等主题磁暴期间超低频波的激发和传播的理论研究和建模研究（使用空间天气模型框架），以及探索所涉及的物理机制将是特别重要的。该奖项涵盖的科学问题的各个方面。
