Subsolar elevation of the equatorial electrojet

pure and applied geophysics, 1989
The subsolar elevation of the equatorial electrojet has been produced from satellite solstitial data available from 09 to 15 hr LT using a new approach with the general style of the overhead equivalent current system. It shows the bunching of the current around the dip equator; the return currents of the equatorial electrojet close to the flanks of the

The Equatorial Electrojet

pure and applied geophysics, 1989
The typical quiet day variations of the equatorial electrojet (EEJ) current intensity with time of the day, season, sunspot number, and geomagnetic latitude are presented in terms of the corresponding variations of ΔH which is the deviation of the horizontal component (H) of the geomagnetic field from its steady nighttime level.

On the equatorial electrojet

Journal of Geophysical Research, 1966
During 29 crossings of the geomagnetic dip equator near 80°W longitude in February and July 1964, airborne equipment obtained cross sections of geomagnetic field intensity and ionospheric characteristics. The magnetic anomalies due to the electrojet and the amplitudes of Esq echoes show fair correlation of details and fair-to-good correlation of large ...

Comparison of equatorial electrojet models

Journal of Atmospheric and Terrestrial Physics, 1977
Abstract Comparison of different models of the equatorial electrojet with several observed parameters shows that models using high electron collision frequency are in better agreement. The electron collision frequency in Richmond's (1972) numerical model has been adjusted empirically to fit experimental results.

The equatorial electrojet

Reviews of Geophysics, 1981
An integrated treatment of observations and models of the undisturbed equatorial electrojet is presented. Previous reviews have concentrated on particular aspects of the electrojet phenomenon, such as ground magnetic variations, the counterelectrojet, or E region electron density irregularities and associated plasma instabilities.

Modeling the equatorial electrojet

Journal of Geophysical Research: Space Physics, 1985
The equivalent circuit method has been modified to give greater accuracy and greater detail near the equator in order to model the equatorial electrojet. Electron collision frequencies used in the conductivity model are consistent with laboratory measurements.

The storm-time equatorial electrojet

Journal of Atmospheric and Terrestrial Physics, 1977
A Petrel rocket carrying a double cell rubidium magnetometer was launched from the Thumba Equatorial Rocket Launching Station during the early main phase of a magnetic storm. No ionospheric currents associated with the storm were observed, and the large field depression at the flight time must therefore be attributed to currents at higher altitudes ...
