Observations in support of models, and model-data comparisons. What are the radial, MLT, and field-aligned structures? What evidence is there for interhemispheric asymmetries? 2) The inner magnetospheric electric field: global modeling, observations, and impact. 3) Plasmaspheric plume density distribution. How well do plasmaspheric drainage plumes map to ionospheric SED plumes moving westward? What is the altitude and temporal signature as we move from low to mid to high latitudes? What creates the "lumpy" structure within plumes, and how does this structure evolve? Is the plasma inside late-storm plumes from the magnetosphere, or outflow from a hot-ionosphere high-latitude source? Where are the gaps in understanding? 4) PBL electric field variability. What is the altitude dependence of the variability and what implications does this have for field-aligned currents and the scaling of the magnetic field mapping function / electric field structuring? Do we have enough empirical evidence to make a statement and can data-guided models help? 5) Plasmapause location and structure. How do ionospheric and magnetospheric people locate the plasmapause / PBL? Are these compatible? What forms the structure seen on the PBL inner edge? 6) Wave/particle interactions and macroscale instabilities in the PBL. Where are these located (in plasmasphere, in ducts, on plasmapause, within plume, ..)? Where do they have an impact on particle trajectories through scattering or anomalous heating? 7) Conductivity control of PBL electrodynamics. How is the coupled electric field on PBL field lines affected by ionospheric conductivity in either or both hemispheres? WANT TO SPEAK?
