    Mid‐Latitude Study of Ionospheric Variation Over Iran Associated With Equatorial Ionization Anomaly (EIA), and Artificial Neural Networks Model Development by M. Vazifehkhah Hafteh, A. Mahmoudian, A. Yoshikawa, K. Girgis

    Published 2024-11-01
    “…Abstract The ionosphere over Iran is located on the upper edge of equatorial ionization anomaly (EIA). The Equatorial Electrojet (EEJ) as the proxy of temporal evolution of the EIA is explored using the MAGDAS stations near the magnetic equator during quiet and active geomagnetic conditions. …”

    Variations of Scale Height at F-Region Peak Based on Ionosonde Measurements during Solar Maximum over the Crest of Equatorial Ionization Anomaly Region by Yu-Jung Chuo

    Published 2014-01-01
    “…In this study, we attempt to examine and discuss the variation of scale height, Hm, around the F-layer peak height during high solar activity at the northern crest of the equatorial ionization anomaly (EIA) region. Hm exhibits day-to-day variation and seasonal variation, with a greater average daily variation during daytime in summer. …”
