Solar & Electrojet Control of the Equatorial Sporadic E [PDF]

, 1974
263-268Variations of Es with sunspot activity (R2) have been studied, analyzing different parameters representing the Es layer, from the Ionospheric Data Bulletins, The percentage occurrence of fb Es > 4 MHz is found to be the most reliable parameter ...

Does the Dayside Equatorial Ionospheric Electric Field Respond to Isolated Substorms?

Geophysical Research Letters
Substorms 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.

On Ps6 and longer period geomagnetic pulsations in the Indian equatorial region

Annales Geophysicae
Adopting an appropriate procedure suitable for processing the amplitude-time records based on the two-component spectral analysis technique, the statistical information on Ps6 and other longer periods are worked out on the geomagnetic field registrations

Can lower E-region dust particles be responsible for counter electrojet? [PDF]

Geofísica Internacional, 2008
Ablation of meteors leaves a large number of dust particles of sizes ranging from nanometers to several micrometers in the upper mesospheric region. These dust particles can affect the equatorial E-region conductivities in several ways.

Lunar tidal effects on zonal and meridional equatorial electrojet currents

, 1995
39-44Significant lunar tidal oscillations have been shown to be present in all the three H, D ( = Y) and Z components of the geomagnetic field at the equatorial station Kodaikanal. The variations in H and Y fields are shown to be nearly opposite in phase

A climatological model of the equatorial electrojet based on Swarm satellite magnetic intensity observations

Journal of Space Weather and Space Climate
The Equatorial Electrojet (EEJ) is a spatially localized electric current in the ionospheric dynamo region, flowing along the magnetic dip equator at an altitude of about 110 km, mainly on the dayside.

Satellite measurements of the equatorial electrojet.

Journal of geomagnetism and geoelectricity, 1985
Satellites that observed magnetic field in the near-earth environment are mentioned, before the review of relevant studies of satellite data. The contributions, problems and prospects of satellite observations of equatorial electrojet fields are then critically discussed in relation to the major results from satellite data such as: the deviation of ...
