This is a short-term (less than one-year) effort to organize and plan a workshop to bring together U.S. scientists and lead personnel who are operating individual ground-based magnetometer arrays. The purpose is to explore efficiencies in the management of these arrays and optimize resources by designing a shared framework for integrated data storage, archiving, dissemination, and high-level data products. Since these independent arrays observe different portions of Earth's space environment (Earth-space), their further development and integration has potential for providing a powerful tool for synthesizing information about its global dynamics. The planned shared framework will be separate from the scientific research, proposed and performed by individual investigator teams, and thus will provide much needed continuity for funding the instrumentation and data distribution during lapses in individual research funding. The effects of these interruptions are compounded because observations from these magnetometer arrays are used by the broader research community and in international collaborations, in addition to their use in scientific research by the magnetometer teams, themselves. Efficiencies in the operation and maintenance of ground-based magnetometer arrays as well as in the development of new global high-level data products will strengthen and improve a valuable U.S. infrastructure for exploring Earth-space and understanding its long-term evolution. Ground-based magnetometers make use of signatures in the Earth's magnetic field to explore and understand Earth-space. These signatures provide information about ionospheric currents associated with geomagnetic storms and substorms, the magnetosphere's response to interplanetary shocks, the reconfiguration of currents and convection as the solar wind driving changes, and the propagation of energy through Earth-space carried by long-period plasma waves. They provide the longest record of Earth-space observations and thus are key to our understanding of long-term variations in that environment. Magnetometer arrays are supported and maintained by countries all over the world so the US arrays contribute valuable information to synthesizing an understanding of the global dynamics in Earth-space. Efficiencies in operations and maintenance of these arrays are important to enable the continuing support and further development of this valuable national observing capability.

这是一项短期（不到一年）的工作，目的是组织和规划一个讲习班，使美国科学家和操作各个地面磁力计阵列的主要人员聚集在一起。 其目的是探索这些阵列的管理效率，并通过设计用于集成数据存储、归档、传播和高级数据产品的共享框架来优化资源。 由于这些独立的阵列观测地球空间环境（地球-空间）的不同部分，其进一步发展和整合有可能为综合全球动态信息提供一个强有力的工具。计划中的共享框架将独立于科学研究，由个人研究团队提出和执行，因此将在个人研究资金失效期间为仪器和数据分发提供急需的连续性。这些中断的影响是复杂的，因为来自这些磁强计阵列的观测除了被磁强计小组自己用于科学研究之外，还被更广泛的研究界和国际合作所使用。 地面磁强计阵列的运行和维护以及新的全球高水平数据产品的开发将加强和改善美国探索地球空间和了解其长期演变的宝贵基础设施。地面磁力计利用地球磁场中的特征来探索和了解地球空间。 这些特征提供了与地磁暴和亚暴相关的电离层电流、磁层对行星际冲击的反应、电流和对流随着太阳风驱动力变化的重新配置以及长周期等离子体波携带的能量通过地空传播的信息。 它们提供了地球空间观测的最长记录，因此是我们了解该环境长期变化的关键。 磁强计阵列得到世界各国的支持和维护，因此美国的阵列为综合了解地球空间的全球动态提供了宝贵的信息。有效地操作和维护这些阵列对于能够继续支持和进一步发展这一宝贵的国家观测能力至关重要。
