The X-pattern Merging of the Equatorial Ionization Anomaly Crests

2023
A unique phenomenon {\textendash} merging of Equatorial Ionization Anomaly (EIA) crests, leading to an X-pattern (EIA-X) around the magnetic equator {\textendash} has been observed in the night-time ionospheric measurements by the Global-scale Observations of the Limb and Disk (GOLD) mission.

Lunar Tidal Effect on Equatorial Ionization Anomaly Region in China Low Latitude

Journal of Geophysical Research: Space Physics, 2021
AbstractThe equatorial ionization anomaly (EIA) crest derived from GPS observations, F2‐layer peak height (hmF2), critical frequency (foF2), and equatorial electrojet (EEJ) in China low latitude are used to study the lunar tidal effect on EIA region for the years from 2006 to 2015.

African and American Equatorial Ionization Anomaly (EIA) Responses to 2013 SSW Event

Journal of Geophysical Research: Space Physics, 2022
AbstractThis study investigates the responses of the African and American Equatorial Ionization Anomaly (EIA) regions to 2013 Sudden Stratospheric Warming (SSW) event. The Total Electron Content (TEC) data obtained from chains of Global Positioning System receivers within ±40° geomagnetic latitudes in the African and American sectors were used to ...

Equatorial Ionization Anomaly Crest Parameters Modeling

 Knowing the locations of the north and south Equatorial Ionization Anomaly (EIA) crests and their corresponding widths is essential for characterizing the spatiotemporal and solar activity variations of the low latitude ionosphere. The crest region is characterized by strong electron density gradients that significantly affect GNSS ...

Magnetospheric disturbance effects on the Equatorial Ionization Anomaly (EIA) : an overview

Journal of Atmospheric and Terrestrial Physics, 1991
Abstract The Equatorial lonization Anomaly (EIA) development can undergo drastic modification in the form of an anomalous occurrence at local times outside that of its quiet time development and/or inhibition/enhancement at local times of its normal occurrences.

Equatorial Ionization Anomaly(EIA): Unraveling The Phenomenon of Ionospheric Disturbance

British Journal of Earth Sciences Research
The Equatorial Ionization Anomaly (EIA) refers to a prominent irregularity in the distribution of ionization density within the ionosphere, situated near the magnetic equator, with two distinct crests at around ±150 in magnetic latitude- where ionization densities are significantly higher - and a trough at the magnetic equator in the F2 layer.

Ionosphere equatorial ionization anomaly observed by GPS radio occultations during 2006–2014

Journal of Atmospheric and Solar-Terrestrial Physics, 2015
Abstract A large number of Global Position System (GPS) radio occultation (RO) observations have been accumulated in the University Corporation for Atmospheric Research (UCAR) Constellation Observation System for Meteorology, Ionosphere and Climate (COSMIC) Data Analysis and Archive Center (CDAAC) especially since the launch of COSMIC mission.
