Electric fields in the equatorial ionosphere derived from CHAMP satellite magnetic field measurements
(Elsevier, 2009-03-09)
The day-time eastward equatorial electric field (EEF) in the E-region plays an important role in equatorial ionospheric dynamics. It is responsible for driving the equatorial electrojet (EEJ) current system, equatorial ...
Swarm SCARF equatorial electric field inversion chain
(SpringerOpen, 2013-11-22)
The day-time eastward equatorial electric field (EEF) in the ionospheric E-region plays a crucial role in equatorial ionospheric dynamics. It is responsible for driving the equatorial electrojet (EEJ) current system, ...
The equatorial electrojet during geomagnetic storms and substorms
(American Geophysical Union, 2015-02-16)
He climatology of the equatorial electrojet during periods of enhanced geomagnetic activity is examined using long‐term records of ground‐based magnetometers in the Indian and Peruvian regions. Equatorial electrojet ...
Electric field and magnetometer observations of the equatorial electrojet: An IEEY program
(Instituto Geofísico del Perú, Radio Observatorio de Jicamarca, 1994)
As part of the IEEY program, a chain of magnetometers was deployed along the Peruvian sector crossing the equatorial electrojet. Simultaneous vertical drift measurements were made using Jicamarca's normal I.S. F-region ...
By‐dependent prompt penetrating electric fields at the magnetic equator
(American Geophysical Union, 2002-04-13)
We propose a new type of prompt penetrating electric field effect which seems to be related to the y‐component of the interplanetary magnetic field and the NBZ current system. We report an equatorial electric field pattern ...
Solar cycle effects on the electric fields in the equatorial ionosphere
(American Geophysical Union, 1977-11-01)
The horizontal east‐west electric fields in the equatorial F region are estimated by using the vertical electron drift data over Jicamarca, Peru. The reversal of the electric field from west to east near the sunrise hours ...
Interplanetary drivers of ionospheric prompt penetration electric fields
(Elsevier, 2010-02-10)
In this paper we discussed the penetration effects of common interplanetary magnetic cloud (MC) structures like sheath region, both sheath and magnetic cloud boundary layer (MCBL), MC body, and shock-running into a preceding ...
A real‐time forecast service for the ionospheric equatorial zonal electric field
(American Geophysical Union, 2012-09-18)
The zonal electric field is the primary driver of two important features of the equatorial ionosphere: (1)The Equatorial Ionization Anomaly (EIA), and (2) plasma density irregularities, also known as spread‐F. During ...
Electric fields and zonal winds in the equatorial ionosphere inferred from CHAMP satellite magnetic measurements
(American Geophysical Union, 2007-12-16)
The Equatorial Electrojet (EEJ) produces a strong magnetic signal in measurements of the low‐orbiting CHAMP satellite. Six years of data with more than 30,000 dayside equator crossings provide a unique data basis to study ...
Equatorial zonal plasma drifts measured by the C/NOFS satellite during the 2008–2011 solar minimum
(American Geophysical Union, 2013-06-26)
We use the measurements by the Vector Electric Field Investigation (VEFI) on board the Communication/Navigation Outage Forecasting System (C/NOFS) satellite to study the local time and seasonal‐ and longitudinal‐dependent ...
