Summary:
This is a multi-instrument investigation using both ground and space based systems to investigate the characteristics and dynamics of the ionospheric source plasmas in ion outflow/acceleration regions at the base cusp field lines and in the polar cap. An accurate specification of source plasma characteristics is need to model and understand the injection of ionospheric ions into the magnetosphere during storms. In particular, we will examine the conditions under which lower-latitude enhanced-density ionospheric plasma is supplied to the ion outflow and acceleration regions, and the conditions under which this material is drawn into the polar cap, forming a polar tongue of ionization (TOI). We will employ a wide range of available ground based [incoherent and coherent scatter radar, Global Positioning System (GPS) receivers] and DMSP in-situ satellite diagnostics. The results of our studies will significantly advance knowledge of the temporal evolution and ultimate impact of stormtime ionospheric restructuring on the source regions providing outflow of heavy ionospheric ions to the magnetosphere.Performance Year | Reference | Actions |
