AB: We have developed a 3D Hall magnetohydrodynamic (MHD) model with the goal of embedding this high-resolution module into the plasma sheet region of the Lyon-Fedder-Mobarry global MHD model. We intend to investigate the effect of the Hall term on the size and structure of fast flow channels observed in the plasma sheet. Owing to insufficient spatial spacecraft coverage of plasma sheet flow bursts, we appeal to global simulations possessing similar tail flow channels to assess the relative importance of the Hall term in plasma sheet transport. Current global ideal MHD models, however, contain features that are highly resolution dependent. The Hall term imposes a physical size scale on the equations in the plasma sheet, and we plan to quantify the effect of that term on the characteristics of fast flow channels.
