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 ...

The Response Time of Equatorial Ionization Anomaly Crest: A Unique Precursor to the Time of Equatorial Spread F Initiation

Journal of Geophysical Research: Space Physics, 2018
AbstractThe time delay with which the magnitude and location of the total electron content (TEC) at the equatorial ionization anomaly (EIA) crest responds to the mean height of the F layer (hmF2) is examined seasonally using the ionosonde data at Trivandrum and the Global Positioning System data at different stations in the EIA region for low and high ...

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.

A statistical study of the F2 layer stratification at the northern equatorial ionization anomaly

Advances in Space Research, 2019
Abstract Ionograms recorded at Puer station (PUR, 22.7°N, 101.05°E, Dip Latitude 12.9°N) in the Southwest of China from January 2015 to December 2016 were used to study characteristics of the F2 layer stratification at the northern equatorial ionization anomaly.

Theoretical study of the ionospheric plasma cave in the equatorial ionization anomaly region

Journal of Geophysical Research: Space Physics, 2014
Abstract This paper investigates the physical mechanism of an unusual equatorial electron density structure, plasma cave, located underneath the equatorial ionization anomaly by using theoretical simulations. The simulation results provide important new understanding of the dynamics of the equatorial ionosphere.

Storm-time characteristics of the equatorial ionization anomaly in the East African sector

Advances in Space Research, 2015
Abstract The equatorial ionization anomaly (EIA), inferred from the electron density profile, was used to study the ionospheric effect of 11 March 2011, 06 April 2011, 09 March 2012 and 01 October 2012 geomagnetic storms in the East African sector. The electron density profile was reconstructed from slant total electron content (sTEC) measurements ...

Study on the Suppression of Equatorial Ionization Anomaly Crest Observed by CSES‐01

Journal of Geophysical Research: Space Physics
Abstract The Langmuir Probe (LAP) on board the China Seismo‐Electromagnetic Satellite (CSES‐01) has repeatedly observed an unexpected suppression of the equatorial ionization anomaly (EIA) crest in its retrieved electron density (Ne) data.
