Martian Ionosphere Electron Density Prediction Using Bagged Trees [PDF]
, 2022 The availability of Martian atmospheric data provided by several Martian missions broadened the opportunity to investigate and study the conditions of the Martian ionosphere. As such, ionospheric models play a crucial part in improving our understanding of ionospheric behavior in response to different spatial, temporal, and space weather conditions ...

Production of Small-Scale Alfvén Waves by Ionospheric Depletion, Nonlinear Magnetosphere-Ionosphere Coupling and Phase Mixing [PDF]
J. Geophys. Res. Space Physics 118 (2013) 1-12, 2013 Rockets and satellites have previously observed small-scale Alfv\'en waves inside large-scale downward field-aligned currents and numerical simulations have associated their formation with self-consistent magnetosphere-ionosphere coupling. The origin of these waves was previously attributed to ionospheric feedback instability, however we show that they

Quiet time F2-layer disturbances: seasonal variations of the occurrence in the daytime sector [PDF]
Annales Geophysicae, 2009 Earlier revealed seasonal/latitudinal variations of the occurrence for positive and negative F2-layer Q-disturbances have been interpreted in the framework of the present-day concept of the thermosphere-ionosphere interaction. The basic process is the

Limb sounders tracking topographic gravity wave activity from the stratosphere to the ionosphere around midlatitude Andes [PDF]
, 2015 Several studies have shown that the surroundings of the highest Andes mountains at midlatitudes in the Southern Hemisphere exhibit gravity waves (GWs) generated by diverse sources which may traverse the troposphere and then penetrate the upper layers if ...

Ionospheric convection and equivalent ionospheric currents in the dayside high‐latitude winter ionosphere [PDF]
Journal of Geophysical Research: Space Physics, 1999 Ionospheric convection inferred from Super Dual Auroral Radar Network (SuperDARN) HF radar measurements is compared with an equivalent ionospheric convection derived from ground magnetometer data in the dayside winter high‐latitude ionosphere. Although there was general agreement between observed convection patterns produced by radars and magnetometers,
