Rocket experiments for spectral estimation of electron density fine structure in the auroral and equatorial ionosphere and preliminary results [PDF]
Sounding rockets equipped to monitor electron density and its fine structure were launched into the auroral and equatorial ionosphere in 1980 and 1983, respectively. The measurement electronics are based on the Langmuir probe and are described in detail.

Effects of propagation parallel to the magnetic field on the type 1 electrojet irregularity instability [PDF]
A simple analysis is presented which indicates that Type 1 irregularities which have a slight component of propagation along the magnetic field may be more unstable than those which propagate across the field.

Does the Dayside Equatorial Ionospheric Electric Field Respond to Isolated Substorms?
Geophysical Research LettersSubstorms are known to induce global magnetosphere‐ionosphere coupling. However, the specific response of the dayside ionospheric electric field and its influence on the equatorial electrojet (EEJ) remain controversial.
