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，目的是组织和计划一次研讨会，将操作单独地面磁力计阵列的美国科学家和领导人员聚集在一起。 目的是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探索这些阵列的管理效率并优化资源。 由于这些独立的阵列观测地球空间环境（地空）的不同部分，因此它们的进一步发展和集成有潜力为合成有关其全球动态的信息提供强大的工具。计划中的共享框架将与科学研究分开，由个体研究人员团队提出和执行，因此将为个体研究经费中断期间的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，因为这些磁力计阵列的观测结果除了被磁力计团队本身用于科学研究之外，还被更广泛的研究界和国际合作所使用。 地面磁力计阵列的运行和维护以及新的全球高级数据产品的开发效率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风暴和亚暴相关的电离层电流、磁层对行星际冲击的响应、太阳风驱动变化时电流和对流的重新配置以及长周期等离子体波携带的能量在地球空间传播的信息。 它们提供了最长的地球-空间观测记录，因此是我们了解该环境的长期变化的关键。 磁力计阵列受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。这些阵列的运行和维护效率对于持续支持和进一步发展这一宝贵的国家观测能力非常重要。
