HF PUMP-INDUCED ELECTRON HEATING AND ARTIFICIAL AIRGLOW AT HIGH LATITUDES: ASPECT ANGLE DEPENDENCE

Large electron temperature increases (~3000 K) in the ionospheric F-region, produced by powerful HF wave injection, were measured using the EISCAT incoherent scatter radar near Tromsø, Norway, on 7 October 1999. Magnetic field-aligned measurements showed HF-initiated ion outflows reaching several hu...
