The outer plasmasphere is highly structured and very dynamic across a broad range of time and length scales. This is due to the interplay between refilling on the dayside and the erosion of the outer plasmasphere caused by variable magnetospheric convection. New results using data from geosynchronous orbit emphasize the importance of substorms to the structure and dynamics of the plasmasphere and suggest that the substorm growth phase plays an important role in populating the nightside inner magnetosphere with dense, cold plasma. Recent multi-satellite studies that examine plasmaspheric dynamics during the growth and expansive phases of substorms are reviewed.
