Electrodynamics in the low and middle latitude ionosphere: a tutorial
(Elsevier, 2004-03-24)
Electric fields in the low and middle latitude ionosphere result from currents driven internally by neutral winds and gravity, and externally by applied potentials. The resulting internal electric polarization fields arise ...
Long‐duration penetration of the interplanetary electric field to the low‐latitude ionosphere during the main phase of magnetic storms
(American Geophysical Union, 2005-11-26)
It is well known that the interplanetary electric field can penetrate to the low‐latitude ionosphere. It is generally believed that the penetration of electric fields can last only for ∼30 min because of the shielding ...
A measure of ionospheric irregularities: zonal velocity and its implications for L-band scintillation at low-latitudes
(2021-09-01)
We estimate the zonal drift velocity of small-scale ionospheric irregularities at low latitude by leveraging the spaced-receivers technique applied to two GNSS receivers for scintillation monitoring installed along the ...
Response of the topside and bottomside ionosphere at low and middle latitudes to the October 2003 superstorms
(American Geophysical Union, 2015-07-14)
Ionospheric observations from the ground‐based GPS receiver network, CHAMP and GRACE satellites and ionosondes were used to examine topside and bottomside ionospheric variations at low and middle latitudes over the Pacific ...
Ionospheric anomalies preceding the low-latitude earthquake that occurred on April 16, 2016 in Ecuador
(Elsevier Ltd, 2019-01)
A catastrophic seismic event of M w 7.8 occurred on April 16, 2016 in Ecuador. As with some other major earthquakes, many human lives were lost. Thus in the last two decades, the search for seismo-ionospheric signatures ...

Equatorial and low latitude ionospheric effects during sudden stratospheric warming events: Ionospheric effects during SSW events
(Springer, 2012)
There are several external sources of ionospheric forcing, including these are solar wind-magnetospheric processes and lower atmospheric winds and waves. In this work we review the observed ion-neutral coupling effects at ...
Enhanced lunar semidiurnal equatorial vertical plasma drifts during sudden stratospheric warmings
(American Geophysical Union, 2011-11-15)
Large scale electrodynamic and plasma density variations in the low latitude ionosphere have recently been associated with sudden stratospheric warming (SSW) events. We present empirical models of largely enhanced lunar ...
Physics‐based forecasts of equatorial radio scintillation for the Communication and Navigation Outage Forecasting System (C/NOFS)
(American Geophysical Union, 2005-12-28)
The plans for producing long‐term (6–24 hour) forecasts of equatorial plasma structure and radio scintillation for the Communication and Navigation Outage Forecasting System (C/NOFS) program are described. We discuss the ...
Ionospheric response to the 2009 sudden stratospheric warming over the equatorial, low, and middle latitudes in the South American sector
(American Geophysical Union, 2015-09)
The present study investigates the ionospheric total electron content (TEC) and F-layer response in the Southern Hemisphere equatorial, low, and middle latitudes due to major sudden stratospheric warming (SSW) event, which ...
