Classification of High‐Latitude Source Region‐Based Ionospheric Scintillation Signatures Using Machine Learning

Journal of Geophysical Research: Machine Learning and Computation
This study investigates ionospheric scintillation signatures in GNSS signals at high latitudes with Machine Learning (ML), focusing on different irregularity generation mechanisms in major regions of the ionosphere.

Intermittency in the integrated power of ionospheric density fluctuations

Journal of Space Weather and Space Climate
The occurrence of ionospheric irregularities poses a significant challenge to Global Navigation Satellite Systems (GNSS) by disrupting signal propagation and causing loss of lock (LOL) events. This study investigates the integrated power spectral density

Beyond the Electrostatic Approach: Numerical Simulations of Martian Ionospheric Irregularities

AGU Advances
Numerical simulations play an essential role in the study of ionospheric irregularities. In the past few decades, electrostatic simulations have successfully simulated the nonlinear evolution of terrestrial ionospheric irregularities.
