Ionospheric Nighttime Enhancements at Low Latitudes Challenge Performance of the Global Ionospheric Maps [PDF]
Remote Sensing, 2022 In this study, two ionospheric nighttime enhancement (INE) events at low latitudes are selected to investigate their spatial features through the observations from Global Navigation Satellite System (GNSS) receivers and ionosondes. For the first time, we present the detailed spatial pictures of premidnight and postmidnight INEs under geomagnetically ...

Coupled electrodynamics in the nighttime midlatitude ionosphere [PDF]
Geophysical Research Letters, 2001 We describe a new, self‐consistent scenario in which sporadic‐E doublets, height bands of upward‐displaced F‐layer profiles, F‐region plasma depletions, and radar backscatter plumes, are all manifestations of a coupled electrodynamical response by the nighttime midlatitude ionosphere to the presence of a traveling ionospheric disturbance (TID). We show

Lightning-driven inner radiation belt energy deposition into the atmosphere: implications for ionisation-levels and neutral chemistry [PDF]
Annales Geophysicae, 2007 Lightning-generated whistlers lead to coupling between the troposphere, the Van Allen radiation belts and the lower-ionosphere through Whistler-induced electron precipitation (WEP).

Triangulating the height of cosmic noise absorption: A method for estimating the characteristic energy of precipitating electrons [PDF]
, 2010 Energetic electrons (tens to hundreds of keV) deposit significant energy into the D layer of the ionosphere. Riometers provide a means of monitoring this electron precipitation by measuring the associated cosmic noise absorption (CNA), but individually ...

Time-Varying Seismogenic Coulomb Electric Fields as a Probable Source for Pre-Earthquake Variation in the Ionospheric F2-Layer [PDF]
Journal of Astronomy and Space Sciences, 2017 The electric coupling between the lithosphere and the ionosphere is examined. The electric field is considered as a timevarying irregular vertical Coulomb field presumably produced on the Earth’s surface before an earthquake within its epicentral zone by
