Abstract:
The Active Magnetosphere and Planetary Electrodynamics Response Experiment (AMPERE) provides one of the few in-situ datasets that allows studies of global properties of magnetosphere-ionosphere (M-I) interactions. The characterisation of the Birkeland currents, sensed by the Iridium constellation of satellites for both hemispheres simultaneously, is possible particularly for storm-time events. Other data sets (e.g. HF radar) that provide large spatial coverage may also be combined with AMPERE data in order to understand hemisphere differences in power input. In this presentation, we focus on the ability of AMPERE data to provide details of M-I coupling in both hemispheres simultaneously. The presentation will be illustrated using examples showing comparisons from north and south hemisphere Birkeland current configurations and Poynting flux.
