A realistic fully time-dependent computer model, denominated LION (Low-latitude Ionospheric) model, that simulates the dynamic behavior of the low-latitude ionosphere is presented. The time evolution and spatial distribution of the ionospheric particle densities and velocities are computed by numerically solving the time-dependent, coupled, nonlinear system of continuity and momentum equations ...

Using observations from the Global-scale Observations of Limb and Disk (GOLD) mission, we investigate post-sunset ionospheric responses to September 2019 Antarctic sudden stratospheric warming –first ever a synoptic perspective. reveal prevalent quasi-6-day periodicity in equatorial ionization anomaly region over South America Atlantic, coincident with enhanced wave (Q6DW) activity mesosphere (...

Based on nearly 4.6 million radio occultation (RO) ionospheric profile data from Constellation Observing System for Meteorology, Ionosphere, and Climate satellites in 2006–2020, a global three-dimensional electron density model was constructed with new concept. The 3D ionosphere structure divided into total 338,661 grids longitude intervals of 10°, latitude 2°, height 5 km. On each grid, the is...

Abstract Recent studies revealed that the long-lasting daytime ionospheric enhancements of Total Electron Content (TEC) were sometimes observed in Asian sector during recovery phase geomagnetic storms (e.g., Lei (J Geophys Res Space Phys 123: 3217–3232, 2018), Li 125: e2020JA028238, 2020). However, they focused only on dayside ionosphere, and no dedicated have been performed to investigate nigh...
