This project reorganizes and enhances the UCLA ground-based magnetometers in the United States, forming a network of fourteen Surface Magnetic Assessment in Real Time (SMART) stations. The SMART network will be used to answer unsolved questions about the plasmasphere. Students will be trained in the hardware and software implementations and in plasmasphere research. The SMART data will be made available to the scientific community and provide an important enhancement in the locations where magnetometer observations are collected to monitor space weather hazards such as geomagnetically induced currents.The objective of the research is better determination of seasonal and local time variations in plasmaspheric density using a remote sensing technique based on field-line resonances, obtaining statistics of events analyzed by magnetoseismology, and providing mid-latitude magnetometer data to the wider community. The methodology is deployment of updated magnetometers in an array of 14 sites in the USA in three meridional chains that connect with meridional chains operated by other groups in Canada.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目重组和加强了美国加州大学洛杉矶分校的地面磁力仪，形成了一个由14个真实的地表磁力评估站组成的网络。SMART网络将用于回答有关等离子体质谱仪的未解决问题。学生将接受硬件和软件实施以及等离子体生物学研究方面的培训。SMART数据将提供给科学界，并在收集磁强计观测数据以监测地磁感应电流等空间天气危害的地点提供重要的改进，研究的目的是利用基于场线共振的遥感技术更好地确定等离子体层密度的季节性和当地时间变化，获得磁震学分析的事件统计数据，并向更广泛的社区提供中纬度磁力计数据。该方法是在美国的14个站点中部署更新的磁力计，这些站点位于与加拿大其他团体运营的磁力链连接的三个磁力链中。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
