NASA's THEMIS mission (Time History of Events and Macroscale Interactions during Substorms) included support for an extended network of Ground-Based Observatories (GBOs) with coverage over the North American auroral regions. Each station is equipped with a white-light auroral imager and a magnetometer providing an almost global-scale coverage of auroral phenomena. This project will extend the operation of the US-managed portion of the THEMIS-GBO network now that the NASA mission is being phased out. The Canadian portion of the THEMIS-GBO system will be funded through 2012 with option to renew/continue it until 2015. This award will enable the uninterrupted operation of the entire network until 2015. The observations made by the THEMIS-GBO network are strongly synergistic with other observational facilities supported by NSF and by the Canadian Space Agency. Among these other facilities are the Advanced Modular Incoherent Scatter Radars (AMISR) located at Poker Flat and Resolute Bay, and the many Super Dual Auroral Radar Network (SuperDARN) coherent scatter radars located in the northern hemisphere. Data from the THEMIS-GBO network will be made available to the general science community and will support scientific research on a wide variety of topics, including the appearance and disappearance of auroral arcs, the role of small-scale structures in auroral arcs, the relationship between auroral phenomena and the large-scale ionospheric convection, the relationship of polar-cap arcs to open and/or closed magnetic field lines, the current systems associated with auroral arcs and the properties of magnetic substorms during solar maximum as compared to solar minimum. These research topics all have relevance to our understanding of space weather and the effects space weather can have on technological systems. The project will provide direct research experience for undergraduate students.

NASA的Themis Mission（在近代期间事件和宏观互动的时间历史）包括对扩展基于地面的观测值（GBO）网络的支持，并在北美极光地区进行了覆盖。 每个站都配备了白色光的极光成像仪和磁力计提供了极光现象的几乎全球规模的覆盖范围。 现在，该项目将扩展到由NASA任务淘汰，该项目将扩大由Themis-GBO网络的运行。 THEMIS-GBO系统的加拿大部分将在2012年资助，以续订/继续为止，直到2015年。该奖项将使整个网络的不间断运行能够直到2015年。Themis-GBO网络的观察结果与NSF和加拿大Space Agencations支持的其他观察设施具有强烈的协同作用。 这些设施包括位于扑克平坦和脱落湾的高级模块化散射雷达（AMISR），以及位于北半球的许多超双极光雷达网络（Superdarn）相干散点雷达。 Themis-GBO网络的数据将提供给一般科学界，并将支持有关各种主题的科学研究，包括极光弧的外观和消失，小规模结构在极光弧中的作用，极光现象与极尺度的对流型的偏置和/或关闭的旋转界限，或者与距离型的相关的距离，或者是隔离的距离，或者是隔离的距离，或者关闭的距离，或者是隔离的界限。与太阳能最小值相比，太阳能最大值期间的磁化型的性能。 这些研究主题都与我们对太空天气的理解以及空间天气对技术系统的影响相关。 该项目将为本科生提供直接的研究经验。
