Counter-Electrojet Associated Changes in the Equatorial Anomaly: Part I -Evidence of Reversal of Upward Drifts [PDF]

, 1980
35-39Ionosonde data from two stations and ionospheric electron content data from five stations in the Indian zone have been used in conjunction with the ground magnetic data to study the changes in the equatorial anomaly associated with counter ...

Storm sudden commencements in geomagnetic H, y and Z fields at the equatorial electrojet station, Annamalainagar

, 1998
The signature of storm sudden commencements at the Equatorial Electrojet Station, Annamalainagar, are shown to consist of a positive impulse in horizontal field, H, and a negative impulse in eastward field, Y, in the same manner as the solar flare effect

Induced magnetic field of the equatorial electrojet at the surface of the earth

, 1981
The northward component of the induced magnetic field due to the equatorial electrojet at the Earth's surface is calculated using a more realistic local time variaton of the external field due to the electrojet than is provided for by models of the ...

Aspect angle dependence of the E region irregularity velocity at large flow angles [PDF]

, 2007
We present the Doppler velocity observations of 1-m plasma waves in the auroral E region by the Scandinavian Twin Auroral Radar Experiment (STARE) Norway VHF coherent radar in the context of simultaneous and coincident measurements of electron and ion ...

Geomagnetic storm effects on zonal and meridional equatorial electrojet currents

, 1997
The sudden commencements of geomagnetic storms at the equatorial electrojet station Kondaikanal are characterized by simultaneous increases of both the horizontal field H and the westerly declination D(W) or the decrease of eastward field, Y.

Equatorial Ionospheric VTEC Perturbations During the 21 June 2020 Solar Eclipse

Earth and Space Science
The annular solar eclipse of 21 June 2020, provided a valuable opportunity to examine the ionospheric response to celestial events. This study analyzes variations in Vertical Total electron content (VTEC) over the equatorial region using data from the ...

Complexities of counter equatorial electrojet currents [PDF]

, 1992
89-96Features of an unusual partial counter electrojet observed on 21 July 1976 are discussed by comparing the VHF backscatter radar signals, equatorial ionograms, TEC measurements and surface magnetograms on that day and neighbouring quiet days.
