The project is a continuation of an on-going effort to develop a comprehensive model of ionosphere - magnetosphere coupling. The emphasis in this phase of the project will be on coupling the horizontal convective motion with field-aligned transport processes. An important aspect of the work is the inclusion of both magnetospheric drivers (field-aligned currents, hot plasma, field-aligned potential drops, and kinetic instabilities) and ionospheric drivers (varying boundary conditions at low altitudes). The overall goal is to elucidate the interplay between horizontal convection and the microphysics associated with field-aligned transport for different solar cycle, seasonal, and magnetic activity conditions.

该项目是开发电离层-磁层耦合综合模型的持续努力的延续。该项目这一阶段的重点将是将水平对流运动与场对齐的输送过程相结合。这项工作的一个重要方面是纳入了磁层驱动因素(场向电流、热等离子体、场向电位降和动力学不稳定性)和电离层驱动因素(在低海拔变化的边界条件)。总的目标是阐明水平对流和与不同太阳周期、季节和磁活动条件下的场向输运相关的微物理之间的相互作用。
