Typical disturbances of the daytime equatorial F region observed with a high-resolution HF radar [PDF]
Annales Geophysicae, 1998 HF radar measurements were performed near the magnetic equator in Africa (Korhogo 9°24'63''N–5°37'38''W) during the International Equatorial Electrojet Year (1993–1994). The HF radar is a high-resolution zenithal radar.

, 2021 The equatorial electrojet (EEJ) represents a ribbon of intense electric current flowing in the ionospheric E region on the dayside along the dip-equator. The primary reason for the high current density is the geometry of the geomagnetic field with its horizontal field lines at these latitudes.

Enhanced Radiation Exposure of Airline Crew and Passengers During the May 2024 Geomagnetic Storm
Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract Enhanced radiation at aviation altitudes is a concern for flight crew and passengers. During space weather events, solar flares and coronal mass ejection (CME) driven shocks are sources of energetic particles that can reach Earth's near‐space environment and interact with its magnetic field and atmosphere.

Variations of geomagnetic H, D, and Z field intensities on quiet days at west african latitudes
Moldavian Journal of the Physical Sciences, 2009 In the framework of the French participation to the International Equatorial Electrojet Year (IEEY), a network of ten electro-magnetic stations was installed at African latitudes. These stations measured digitally the three components of the magnetic

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract Equatorial plasma bubbles (EPBs) pose significant challenges to trans‐ionospheric radio communication and navigation systems. Because of their disruptive effects, evaluating and predicting them is key for the development of space systems. The influence of geomagnetic activity on EPBs remains unclear, partly due to limited low‐latitude neutral ...

Secondary irregularities in the equatorial electrojet [PDF]
Journal of Geophysical Research, 1967 Although the two-stream instability theory, discussed by Farley, has been quite successful in accounting for many observed features of the plasma-wave irregularities produced in the equatorial electrojet, increased equipmental sensitivity and improved experimental techniques of observing the power spectrum of radio echoes from the electrojet have ...

Statistical Auroral Absorption Model Parameterized by AE Index
Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract Energetic electron precipitation, often in association with enhanced geomagnetic activity, leads to increased D‐region ionization in the auroral region causing auroral absorption. A statistical auroral absorption model is presented for high‐latitudes (poleward of 50° magnetic latitude) based on data collected from 2010 to 2019 from 13 wide ...

Investigation of the response time of the equatorial ionosphere in context of the equatorial electrojet and equatorial ionization anomaly [PDF]
Annales Geophysicae, 2011 Equatorial Electrojet (EEJ) and Equatorial Ionization Anomaly (EIA) are two large-scale processes in the equatorial/low latitude ionosphere, driven primarily by the eastward electric field during daytime.
