Ion Acceleration in the Magnetosphere and Ionosphere


  • Tom Chang


These past 20 years have seen substantial progress in understanding the nature of the plasma domains that play critical roles in the dynamics of the ionosphere and magnetosphere: the diverse auroral plasmas (including the striking inverted V events), the polar cusp and polar wind, the plasmasphere, the bow shock, the magnetotail, the plasma sheet and its boundary and earthward extension. On the other hand, with only a few exceptions, analytic descriptions of the various plasma phenomena that are relevant to the real geometry and physics of the geoplasma environment are generally inadequate.
