Bottom-type scattering layers and equatorial spread F
(European Geosciences Union (EGU), 2004-12)
Jicamarca radar observations of bottom-type coherent scattering layers in the post-sunset bottomside F-region ionosphere are presented and analyzed. The morphology of the primary waves seen in radar images of the layers ...
The equatorial E-region and its plasma instabilities: a tutorial
(European Geosciences Union, 2009-04-02)
In this short tutorial we first briefly review the basic physics of the E-region of the equatorial ionosphere, with emphasis on the strong electrojet current system that drives plasma instabilities and generates strong ...
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 ...
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 ...
Prompt effects of solar wind variations on the inner magnetosphere and midlatitude ionosphere
(Elsevier, 2005)
It is well known that the solar wind can significantly affect high-latitude ionospheric dynamics. However, the effects of the solar wind on the middle- and low-latitude ionosphere are much less studied. In this paper, we ...
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 ...

Statistical analysis of radar observed F region irregularities from three longitudinal sectors
(European Geosciences Union, 2013-12)
Equatorial Spread F (ESF) is a manifestation of ionospheric interchange instabilities in the nighttime equatorial F region. These instabilities generate plasma density irregularities with scale sizes ranging from centimetres ...
A new source of the midlatitude ionospheric peak density structure revealed by a new Ionosphere‐Plasmasphere model
(American Geophysical Union, 2016-02-02)
The newly developed Ionosphere‐Plasmasphere (IP) model has revealed neutral winds as a primary source of the “third‐peak” density structure in the daytime global ionosphere that has been observed by the low‐latitude ...
Simultaneous 6300 Å airglow and radar observations of ionospheric irregularities and dynamics at the geomagnetic equator
(European Geosciences Union (EGU), 2018-03-22)
In March 2014 an all-sky imager (ASI) was installed at the Jicamarca Radio Observatory (11.95°S, 76.87°W; 0.3°S MLAT). We present results of equatorial spread F (ESF) characteristics observed at Jicamarca and at low ...
