A study of the generation mechanisms of high latitude and equatorial F-region irregularities using DE-2 data

Characteristics of small scale (approx. 10 km and smaller) density irregularities in the various domains of the high latitude F-region in the winter (i.e., dark) hemisphere are examined. The DE-2 spacecraft has made it possible for the first time to study simultaneously on a systematic basis the spectral characteristics of not only the density irregularities but of the velocity irregularities, as well. Density irregularity spectra near auroral acceleration and shear regions have been studied using AE-D data.
