SUMMARY:John Coxon (Southampton): Temporal behaviour of Birkeland current
 s in AMPERE
TZID:Europe/London
UID:20200603-8a17841a7042f22601705cf024c71b4f@warwick.ac.uk
CREATED:20200601T115759Z
DESCRIPTION:Abstract: Birkeland currents\, also known as field-aligned cu
 rrents\, are currents which flow along Earth’s magnetic field lines\, el
 ectrodynamically linking the magnetopause and partial ring current to th
 e ionosphere. I use observations from the Active Magnetosphere and Plane
 tary Electrodynamics Response Experiment (AMPERE) to investigate the Bir
 keland currents through the polar cap and the timescales of those curren
 ts. I will start by reviewing my work examining Birkeland currents in th
 e context of the Dungey Cycle and particularly look at their magnitudes 
 and location with respect to magnetic reconnection. Then\, I will move o
 nto looking at the timescales of currents’ reaction to components of the
  Interplanetary Magnetic Field (IMF) using the Spatial Information from 
 Distributed Exogenous Regression (SPIDER) technique pioneered by Robert 
 Shore at the British Antarctic Survey. I will follow this with some prel
 iminary results of using SPIDER in a case study of a geomagnetic storm. 
 If time allows\, I will then present some wildly preliminary work which 
 I’m very excited about.
