Published in 2017 at "Advances in Space Research"

DOI: 10.1016/j.asr.2017.03.039

Abstract: Abstract In addition to multi-scale spatio-temporal trends that shape the ionosphere variability, the ionosphere responds to the disturbances that are solar, geomagnetic and seismic in origin. In this study, post-seismic ionospheric disturbances are investigated retrospectively… read more here.

Published in 2020 at "Advances in Space Research"

DOI: 10.1016/j.asr.2020.04.040

Abstract: Abstract A novel method using single station beacon Relative Slant Total Electron Content (RSTEC) measurements is proposed to estimate the location of Equatorial Ionization Anomaly Trough (EAT). The feasibility of this method is established based… read more here.

Published in 2019 at "Journal of Atmospheric and Solar-Terrestrial Physics"

DOI: 10.1016/j.jastp.2019.01.006

Abstract: Abstract Using total electron content (TEC) data deduced from 18 Global Positioning System (GPS) receivers in Africa and Middle East, we investigated the morphology of the equatorial ionization anomaly (EIA) and its underlying variations before,… read more here.

Published in 2021 at "Space Weather"

DOI: 10.1029/2020sw002690

Abstract: Although it is accepted that the electron density double peaks of the Equatorial Ionization Anomaly (EIA) generally merge into a single‐peak with increasing altitude and thus the signature of EIA becomes inconspicuous in the higher… read more here.

Published in 2021 at "Space Weather"

DOI: 10.1029/2021sw002812

Abstract: Aside from the influence of forcing from above on the ionosphere during space weather, forcing from below also have significant influence on the ionosphere. This study investigates responses of the equatorial ionization anomaly (EIA) in… read more here.
