This grant supports an investigation into the dynamics behind the coupling of Earth's ionosphere and magnetosphere. It is important to understand how Earth's magnetic field couples to the outer layers of the atmosphere as a background to understanding how space weather effects the very near-Earth environment and ultimately societies most critical space and ground based assets. This study supports education and training in the fields of data analysis, numerical simulations and space plasma physics for one PhD student. In addition, it includes collaboration between national labs (Air Force Research Laboratory and U.S. Naval Research Laboratory) and an academic institution (Embry-Riddle Aeronautical University). The results of this study will be disseminated through public outreach events including lectures at local high schools.This project will specifically examine the relative importance of the field line resonator and the ionospheric Alfven resonator in generating Ultra Low Frequency waves at middle and low latitudes. This will be achieved through use of reduced two-fluid magnetohydrodynamics model in 2D and 3D which includes ionospheric conductance and collisions. SAMI is Another Model of the Ionosphere 3 (SAMI3) model data and Communication/Navigation Outage Forecasting System (C/NOFS) satellite data will provide ionospheric input to the model. The outcomes will be compared with magnetic observations conducted at South American Meridional B-Field Array (SAMBA) stations in Antarctica and Chile.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.

这笔赠款支持对地球电离层和磁层耦合背后的动力学进行调查。必须了解地球磁场如何与大气外层耦合，以此作为了解空间气象如何影响近地环境并最终影响社会最关键的空间和地面资产的背景。这项研究支持对一名博士生进行数据分析、数值模拟和空间等离子体物理学领域的教育和培训。此外，它还包括国家实验室（空军研究实验室和美国海军研究实验室）与学术机构（安柏瑞德航空大学）之间的合作。将通过在当地高中举办讲座等公共宣传活动传播这一研究结果，该项目将具体审查场线谐振器和电离层阿尔芬谐振器在中低纬度产生超低频波方面的相对重要性。这将通过使用简化的二维和三维双流体磁流体力学模型来实现，其中包括电离层电导和碰撞。SAMI是另一种电离层模型3（SAMI 3）模型数据，通信/导航中断预报系统（C/NOFS）卫星数据将为该模型提供电离层输入。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。
