3-D Ionospheric Electron Density Variations during the 2017 Great American Solar Eclipse: A Revisit
(Multidisciplinary Digital Publishing Institute, 2023-08-31)This paper studies the three-dimensional (3-D) ionospheric electron density variation over the continental US and adjacent regions during the August 2017 Great American Solar Eclipse event, using Millstone Hill incoherent ... -
Conjugate Ionospheric Perturbation During the 2017 Solar Eclipse
(American Geophysical Union (AGU), 2021-01-16)We report new findings of total electron content (TEC) perturbations in the southern hemisphere at conjugate locations to the northern eclipse on August 21, 2017. We identified a persistent conjugate TEC depletion by 10%–15% ... -

Impacts of the Sudden Stratospheric Warming on Equatorial Plasma Bubbles: Suppression of EPBs and Quasi-6-Day Oscillations
(MDPI AG, 2024-04-21)This study investigates the day-to-day variability of equatorial plasma bubbles (EPBs) over the Atlantic–American region and their connections to atmospheric planetary waves during the sudden stratospheric warming ... -
The nighttime ionospheric response and occurrence of equatorial plasma irregularities during geomagnetic storms: a case study
(Springer Singapore, 2021-11-01)Abstract Recent studies revealed that the long-lasting daytime ionospheric enhancements of Total Electron Content (TEC) were sometimes observed in the Asian sector during the recovery phase of geomagnetic ... -
Salient Midlatitude Ionosphere‐Thermosphere Disturbances Associated With SAPS During a Minor but Geo‐Effective Storm at Deep Solar Minimum
(American Geophysical Union (AGU), 2021-06-23)This work conducts a focused study of subauroral ion-neutral coupling processes and midlatitude ionospheric/thermospheric responses in North America during a minor but quite geo-effective storm on September 27–28, 2019 ... -

Traveling Ionospheric Disturbances in the Vicinity of Storm‐Enhanced Density at Midlatitudes
(American Geophysical Union (AGU), 2022-08)This study provides first storm time observations of the westward-propagating medium-scale traveling ionospheric disturbances (MSTIDs), particularly, associated with characteristic subauroral storm time features, storm-enhanced ...
