Multi‐Scale Ionospheric Poynting Fluxes Using Ground and Space‐Based Observations

Three events are presented where high-resolution measurements from the Swarm satellites coincided with excellent F-region ionospheric coverage The Super Dual Auroral Radar Network (SuperDARN). Large-scale convection patterns SuperDARN, together field-aligned-current he Active Magnetosphere and Planetary Response Experiment (AMPERE), provide information on quasi-static dynamics traversed by Swarm. Because observations orbital path favorable SuperDARN/AMPERE observing conditions, it was possible to filter electric field into a component that agreed SuperDARN field. residual is thus indicative of small- mesoscale not captured field-aligned current (FAC) patterns. Calculations Poynting flux between different instruments show small-to mesoscales can be highly variable within structures like FACs. In shown, medium-scale fluxes occasionally dominate over those large-scale processes.
