Investigation of subauroral ion drifts and related field-aligned currents and ionospheric Pedersen conductivity distribution

Investigation of subauroral ion drifts and related field-aligned currents and ionospheric Pedersen conductivity distribution

Based on Astrid-2 satellite data, results are presented from a statistical study on subauroral ion drift (SAID) occurrence. SAID is a subauroral phenomenon characterized by a westward ionospheric ion drift with velocity greater than 1000m/s, or equivalently, by a poleward-directed electric field...
