Magnetic field perturbations in the auroral zone are produced by a combination of distant ionospheric and local ground induced currents. Spatial and temporal structure of these currents is scientifically interesting and can also have a significant influence on critical infrastructure.
Ground-based magnetometer networks are an essential tool for studying these phenomena, with the existing...
We examine the conditions under which along-track ion flows and the average ion mass can be obtained by combining electric current measurements of the European Space Agency's Swarm Electric Field Instrument (EFI) Langmuir probes. Each EFI is equipped with two spherical probes and a planar probe. Using the orbit-motion limited approximation, we combine the expressions for the electric currents...
We report the findings of a case study in which in the Enhanced Polar Outflow Probe (e-POP) passed over a stable double-arc system in the pre-midnight sector. The arcs’ near infrared emissions were identified using e-POP’s Fast Auroral Imager (FAI). We have assimilated measurements from e-POP’s highly-resolved contemporaneous dataset in order to provide new and compelling insight into the...
