Invited Speaker / Conférencier(ère) invité(e)

There has been an exciting recent development in auroral research associated with the discovery of a new subauroral phenomenon called STEVE (Strong Thermal Emission Velocity Enhancement). Although STEVE has been documented by amateur night sky watchers for decades, it is a new upper atmosphere phenomenon. Observed first by amateur auroral photographers, STEVE appears as a narrow luminous...

2230. Science Highlights from the Swarm Electric Field Instruments

Prof. David Knudsen (University of Calgary)

Atmospheric and Space Physics / Physique atmosphérique et de l'espace (DASP-DPAE)

Oral (Non-Student) / Orale (non-étudiant(e))

After four years in orbit, the Swarm Electric Field Instruments have contributed to dozens of scientific studies on topics that include the electrodynamics of auroral arcs, supersonic flow channels associated with region 1/2 currents and sub-auroral ion drifts, polar cap patch dynamics, Poynting flux, and magnetosphere-ionosphere coupling via Alfven waves. This talk will overview capabilities...

2241. Assessment of Swarm ionospheric flow measurements by inter-satellite comparisons

Oral (Non-Student) / Orale (non-étudiant(e))

We present recent results from a preliminary inter-satellite comparison of ionospheric flow measurements from the European Space Agency Swarm mission. Swarm consists of three identical satellites in near-polar circular orbits in the topside F region ionosphere. Each spacecraft carries a set of two orthogonal thermal ion imagers designed to measure full ion flow vectors twice per second. The...
