Emphasis has been placed on the analysis of multi-instrument experiments investigating the physics of the auroral oval/polar cap boundary and the vicinity of the plasmapause and inner edge of the ring current at mid-latitudes utilizing existing data sets from Millstone Hill and other incoherent scatter radars and available satellite overflights and supporting ground-based information. Ionospheric signatures of the cusp and the mechanisms involved in large-scale plasma transport into the polar cap during magnetic storms have been investigated. Data from Air Force sensors on DMSP satellites have been combined with ground-based observations to examine intense oxygen ion outflow, localized intensifications of the convection electric field, and SAR arcs all of which occur equatorward of the main auroral enhancements during geomagnetic storms. The characteristics of the ring current and plasmasheet particle populations are closely coupled to these ionospheric phenomena.
