AB: The growth and expansion phases of substorms have been extensively analyzed, while the recovery phase has not received as much attention by the magnetospheric research community. The recovery phase has been generally assumed to be merely a return of the system to the quiet time state, while more detailed analysis has shown it to have a fairly complex process. This study will be looking at the recovery phase in greater detail. Also, the ability to look at substorm events both telescopically and microscopically has been realized by using the CLUSTER constellation in conjunction with POLAR and various geostationary satellites. Using events from the 2002 Cluster tail season, we will be focusing on the recovery phase of substorm sequences. CLUSTER data will provide a microphysical picture of the event, while the entire radial constellation beginning with solar wind data at the L1 point, through geostationary satellites, POLAR and CLUSTER will enable us to view the macroscopic picture. We have used the Lyon-Federer-Mobarry MHD simulation code to numerically model several of these events. These observations and model comparisons are giving us a better understanding of the recovery phase of the substorms.
