Goals
The overarching goal of this focus group is to understand the physics of collisionless magnetic reconnection on magnetospheric length scales (hundreds of ion inertial lengths). To this end, we have identified several broad questions to be addressed during the course :
- Q1: Can global resistive magnetohydrodynamics (MHD) codes accurately model magnetospheric reconnection?
- Q2: How does the physics of collisionless reconnection observed in Particle-In-Cell (PIC) simulations scale up to reality?
- Q3: Can we extend global resistive MHD models to include microscale physics which is needed to accurately model reconnection?
The three questions Q1-Q3 are motivated by a currently popular approach to GGCM development known as the MHD Spine" approach.
