This project will make significant enhancements to Assimilative Mapping Ionospheric Electrodynamics (AMIE) model, and will use the new capabilities to investigate several scientific questions of fundamental importance to magnetosphere-ionosphere coupling and dynamic space weather events. Specifically, the model will be constructed using a spherical wavelet basis, affording better representation of fine structure, and will specify magnetic potential associated with inclined magnetic field lines. Conductances will be incorporated more accurately, and an assimilative framework will be added to allow for the time evolution of the state variables and the adaptive update of error covariances. Furthermore, space-based data from AMPERE, DMSP, POES, CHAMP, and additional new sources will be assimilated. The updated AMIE model will be used for a series of event studies to investigate localized and global energy deposition and plasma convection at high latitudes, important drivers for the thermosphere/ionosphere system which can have large effects on communication and navigation systems.

该项目将对同化映射电离层电动力学（AMIE）模型进行重大增强，并将利用新功能来研究对磁层-电离层耦合和动态空间天气事件具有根本重要性的几个科学问题。 具体而言，该模型将使用球形小波基来构建，从而提供精细结构的更好表示，并且将指定与倾斜磁场线相关联的磁势。 电导将被纳入更准确，同化框架将被添加到允许的状态变量的时间演变和自适应更新的误差协方差。 此外，还将吸收来自AMPERE、DMSP、POES、CHAMP和其他新来源的天基数据。 更新后的AMIE模型将用于一系列事件研究，以调查高纬度地区的局部和全球能量沉积和等离子体对流，这些是热层/电离层系统的重要驱动因素，对通信和导航系统有很大影响。
