Electrodynamic Parameters of the Auroral Oval from Combined Spacecraft and Ground Measurements
(European Space Agency, 2006)
Spacecraft traversing the auroral oval respond primarily to the field-aligned currents at its poleward and equatorward borders that are part of a solenoidal current system. If electric and magnetic field measurements are ...
Time Evolution of the Substorm Current Wedge from Ground and Space-based Magnetic Fields
Over the past several years, intensive efforts have resulted in a significant improvement in the ground instrumentation for auroral studies in North America. A major part of this is due to the THEMIS ground program, both ...
