Net Field-Aligned Currents Observed by Triad.
Abstract
In an appreciable fraction of the Triad passes over the northern auroral oval, a step-like level shift is observed in the component approximately in the dipole east-west direction. This implies that there is a net field-aligned current flowing into or away from the ionsophere in a current sheet parallel to an L-shell. This report discusses the results of detailed analysis of these step-like level shifts and an underlying basic pattern of field-aligned current flowing in the polar cap boundary region.
