Ground-based magnetic field observations continue to play a fundamental role in magnetospheric and ionospheric research. The Magnetometer Array for Cusp and Cleft Studies (MACCS) is an NSF-funded ground-based array that records and disseminates important magnetic field measurements for scientific analyses. MACCS is the only longitudinally-spaced cusp-latitude array in existence and will continue to provide critical data for studies of geospace phenomena including solar wind-magnetosphere and magnetosphere-ionosphere interactions, the dynamics of the cusp/boundary layer/mantle/polar cap regions of the magnetosphere, geomagnetic storms and substorms, and localized instabilities that produce large geomagnetically induced currents which can cause power grid blackouts on Earth. Therefore, MACCS supports understanding and preparation for extreme space weather events which are a risk to national security. Additionally, this project supports the training of undergraduate and graduate student researchersThe project will continue operation of MACCS, an important magnetometer array that has been funded by NSF since 1991 and continue dissemination of the MACCS dataset to the scientific community. A new low-cost magneto-inductive magnetometer sensor will be deployed and tested at MACCS sites. Additionally, scientific studies will focus on: (1) performing detailed studies of high-latitude ULF waves, using multi-instrument ground-based and satellite data including MMS, the Van Allen Probes, and SWARM, (2) Continuing studies of nighttime impulsive magnetic perturbations relevant to geomagnetically induced currents, (3) combining GPS data and magnetic field data from MACCS and neighboring arrays to better understand the dynamics of the ionospheric projections of dayside and nightside boundary domains, (4) using machine learning techniques to study factors influencing relativistic electron fluxes, (5) producing higher-level data products characterizing global ULF waves and turbulence, and (6) carrying out theoretical studies and modeling studies using the Space Weather Modeling Framework of the excitation and propagation of ULF waves through the global magnetosphere-ionosphere system.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.

地面磁场观测继续在磁层和电离层研究中起着基本作用。尖端和裂口研究（MACC）的磁力计阵列是NSF资助的地面阵列，记录并传播重要的磁场测量值，以进行科学分析。 MACC是存在的唯一纵向尖端纬度阵列，并将继续为地理位置现象的研究提供关键数据，包括太阳风层层和磁层 - 磁层 - 磁层相互作用，CUSP/CUSP/CUSP/边界层/边界层/地幔/地形区域的动力学的动力学，磁层的磁层，地理位置，并产生巨大的地理位置，以及定位的统计，并以构成的态度，以及，以至于，以及范围内的磁层和近极范围，以及，以及范围内的磁层和质量范围，以及磁层范围和磁层的范围，以及磁层范围和磁层的变化区域，并产生了磁层/地形区域。电流会导致地球上的电网停电。因此，MACC支持对极端太空天气事件的理解和准备，这是国家安全风险。此外，该项目支持对本科生和研究生研究人员的培训该项目将继续MACC的运行，MACC是一个重要的磁力计阵列，自1991年以来一直由NSF资助，并继续将MACCS数据集传播到科学界。将在MACCS站点部署和测试新的低成本磁电磁计传感器。此外，科学研究将重点介绍：（1）使用多仪器地面和卫星数据进行高纬度ULF波的详细研究，包括MMS，van Allen探针和群，（2）夜间冲动的脉动磁性扰动继续研究与GEMAGNET诱导的近距离型和磁性磁场相关的GPS数据和磁性数据，（3）与GPS数据相关的速度（3） （4）使用机器学习技术来研究影响相对论电子通量的因素，（5）生产较高级别的数据产品，以实现较高的数据来表征全球ULF波和湍流，以及通过ulf of ulf of ulf of ulf of the of the of ulf of the of ulf of of ulf offf of the of ulf， NSF的法定使命，并使用基金会的知识分子优点和更广泛的影响审查标准来评估值得支持。
