2023 Workshop: Equatorial Ionization Anomaly (EIA) and ionospheric irregularities
Note: this workshop will be "Recent advances in the understanding of Equatorial Ionization Anomaly (EIA) and ionospheric irregularities, part 1" in 2023 CEDAR Workshop agenda due to a merging with another proposed workshop.
This session invites presentations related to space and ground-based measurements and modeling efforts that contribute to a better understanding of the development and variability of EIA and ionospheric irregularities (e.g., Scintillations, Equatorial Plasma Bubbles, Spread-F) over low and mid-latitudes.
Equatorial Ionization Anomaly (EIA) and ionospheric irregularities (e.g., Scintillations, Equatorial Plasma Bubbles, Spread-F) have been a major focus of the low and mid-latitude ionospheric research community. The behavior of the IT system is influenced by the solar forcing from above, wave activities from below, traveling atmospheric/ionospheric disturbances (TADs/TIDs) from mid/high latitudes, and the equatorial dynamo process. These factors along with the dynamic processes manifest various thermospheric and ionospheric irregularities (e.g., Scintillations, Equatorial Plasma Bubbles, Spread-F). Further, the geometry (such as magnetic declination angle, terminator alignment), geomagnetic activities, and other conditions (e.g. winds and wave activity) regulate the morphology and variability. Determining these conditions and understanding their interactions have challenged the research community for decades. New and existing satellite measurements (GOLD, ICON, COSMIC), ground-based observations (e.g., GNSS TEC, incoherent/coherent scatter radar, all-sky imagers, ionosonde), and modeling approaches have revealed several new, interesting characteristics about the EIA variability and ionospheric irregularities.
