Summary

We outline, and discuss the calibration of, an experimental method for the measurement of magnetospheric field-aligned currents using coherent scatter radar data. The technique is applied to identify and analyse a localised upward field-aligned current sheet observed in the late afternoon mid-latitude ionosphere. We argue that this current arises from the earthward transport of hot plasma due to ongoing magnetospheric erosion.
