Abstract:
We present work detailing the effects of ionospheric outflow in the magnetosphere during the Sept 27- Oct 4, 2002 and Oct 22- Oct 29, 2002 GEM storms. The Multi-Fluid LFM global MHD code is driven by OMNI solar wind and IMF data and by outflow from the Generalized Polar Wind (GPW) model. The GPW input results in a realistic and dynamic, although not self-consistent, outflow of O+, H+, and He+ from the ionosphere. The validity of this outflow and its entry into the magnetosphere is tested through comparisons to Cluster and geosynchronous spacecraft observations. We show the access of these various populations to the magnetosphere, and we examine their effects on plasma sheet structure and storm time dynamics.
