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）的努力，旨在组织和计划一个研讨会，以将操作个体基于地面磁力计阵列的美国科学家和领导人员汇集在一起​​。 目的是通过设计集成数据存储，归档，传播和高级数据产品的共享框架来探索这些数组管理的效率，并通过设计共享框架来优化资源。 由于这些独立的阵列观察到地球太空环境的不同部分（地球空间），因此它们的进一步发展和整合具有提供强大的工具来综合有关其全球动态信息的强大工具。计划中的共享框架将与个人调查员团队提出和执行的科学研究分开，因此将提供急需的连续性，以资助单个研究资金的失误期间的仪器和数据分配。这些中断的效果更加复杂，因为这些磁力计阵列的观察结果是更广泛的研究社区和国际合作，除了它们在磁力计团队中的科学研究中，它们本身都使用了它们。 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方面的效率将增强和改善有价值的美国基础设施，以探索地球空间和理解其长期发展。地面磁力计利用地球磁场中的特征来探索和理解地球空间。 这些特征提供了有关与地磁风暴和实体相关的电离层电流的信息，磁层对行星际冲击的响应，随着太阳能风的变化的变化，电流的重新配置和对流的重新配置以及对流的反应以及通过长期period plasma浪潮传播的能量传播。 它们提供了地球空间观察的最长记录，因此是我们对这种环境中长期变化的理解的关键。 磁力计阵列得到了世界各地的国家支持和维护，因此美国阵列为综合地球空间全球动态的理解提供了宝贵的信息。这些阵列的运营和维护效率对于使这一宝贵的民族观察能力的持续支持和进一步发展至关重要。
