Abstract. The high-spatial-resolution observations of the au-roral E-region echoes by the Super Dual Auroral Radar Net-work (SuperDARN) HF radar at Pykkvibaer, Iceland con-sidered in a previous study are re-examined. Both the spec-tral power and Doppler velocity of the E-region HF echoes exhibit strong dependence on the slant range and expected off-perpendicular magnetic aspect angle (aspect angle atten-uation). We consider the aspect angle attenuation effects in identification of spectral HF echo types. It is argued that echoes with Doppler velocities close to the nominal value of the ion-acoustic speed Cs (∼350 m/s) and echoes with velocities greatly exceeding the Cs (up to 600 m/s) are more related in their generation mechanisms than pre...
