(2006) A study of aspect angle effects in the E-region irregularity velocity using multi-point electric field measurements. Geophysical Research Letters, 33 (21). L21102. ISSN 0094-8276Full text not available from this repository.
E-region irregularity velocity measured by the STARE Norway VHF radar is considered as a function of magnetic aspect angle α and EISCAT-derived electron drift velocity at 7 locations with α between 0.38° and 2.64°. It is shown that the irregularity line-of-sight (l-o-s) velocity normalized to the electron velocity component V e0 comp exhibits a decrease with an increasing aspect angle for V e0 comp exceeding 500 m/s. The rate of velocity decrease is greater than those reported previously and is close to that predicted by the linear theory of electrojet irregularities without assuming anomalously large collision frequencies.
