| Zusammenfassung |
| We present electron phase space density (PSD) calculations as well as
concurrent Pc5 and chorus wave activity observations during two intense
geomagnetic storms caused by interplanetary coronal mass ejections (ICMEs)
resulting in contradicting net effect. We show that, during the 17 March
2013 storm, the coincident observation of chorus and relativistic
electron enhancements suggests that the prolonged chorus wave activity seems
to be responsible for the enhancement of the electron population in the outer
radiation belt even in the presence of pronounced outward diffusion. On the
other hand, the significant depletion of electrons, during the 12 September
2014 storm, coincides with long-lasting outward diffusion driven by the
continuous enhanced Pc5 activity since chorus wave activity was limited both
in space and time. |
