Society relies upon technologies such as power distribution systems and constellations of communications satellites for daily functioning. These technologies are susceptible to the effects of magnetic storms and other severe space weather. This project will study what factors lead to space weather in an effort to better predict impacts. Additionally, the work will involve undergraduate students from under-represented groups in STEM in research at a primarily undergraduate institution. Additionally, an Artist in Residence program will be developed to increase general science literacy and to make links between space science and art.The science objective is to determine nonlinear metrics that specify the dynamical state of the magnetosphere prior to the onset of, and during, extreme space weather. The research will investigate and statistically characterize, model, and forecast the spatiotemporal fluctuations of the ground magnetic field using advanced mathematical techniques. The central hypothesis is that space weather associated spatiotemporal fluctuations of the geomagnetic field follow the statistics of intermittency-induced criticality. Data will be used from arrays of ground-based magnetometers from high-to-equatorial latitudes.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.

社会的日常运作依赖于诸如配电系统和通信卫星群之类的技术。这些技术很容易受到磁暴和其他恶劣太空天气的影响。该项目将研究导致太空天气的因素，以更好地预测影响。此外，这项工作将涉及来自STEM中代表性不足群体的本科生在一所主要的本科院校进行研究。此外，还将发展一项艺术家驻场计划，以提高一般的科学素养，并将空间科学与艺术联系起来。科学目标是确定在极端空间天气发生之前和期间指定磁层动态状态的非线性指标。该研究将利用先进的数学技术调查和统计表征、建模和预测地磁场的时空波动。中心假设是，与空间天气相关的地磁场时空波动遵循间歇性诱发临界的统计。数据将从高纬度到赤道纬度的地面磁力计阵列中使用。该奖项反映了美国国家科学基金会的法定使命，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。
