Deriving the normalised ion-neutral collision frequency from EISCAT observations

Common programme observations by the EISCAT UHF radar revealed an extended interval, post geomagnetic local noon on 03 April 1992, during which the F-region ion velocity orthogonal to the geomagnetic field was significantly enhanced, to values exceeding 2 km s<sup>–1</sup> correspond...
