Scientific paper

We present a multi-spacecraft study of electric fields and relativistic particles (from hundreds keV to MeV) dynamics during substorms dipolarization events. The data set include ~180 dipolarization events identified by at least 10 nT increase in Bz_GSM observed by Polar spacecraft when close to the magnetic midnight and the equatorial plane. The typical AE indexes during these dipolarization are about ~1000. Some of these dipolarization are also observed simultaneously by Cluster in the magnetotail. Most of these dipolarization events are characterized with relative large amplitude electric fields observed by Polar, with the peak-to-peak value in the range from several mV/m to ~100 mV/m, which can be two orders magnitude larger than what is normally expected during dipolarization. For a significant portion of events, large electric fields (more than ~10 mV/m) observed by Polar are found associated with flux enhancement of energetic particles at Polar and LANL GEO spacecraft. The study will address the role of the electric field that can energize and transport relativistic particles during substorm dipolarization.
