Effects of the 2007 Martian Global Dust Storm on Boundary Positions in the Induced Magnetosphere

The Planetary Science Journal
Mars's magnetosphere is a sensitive system, varying due to external and internal factors, such as solar wind conditions and crustal magnetic fields.

On the Effects of the Solar Wind Structure in the Global Distribution of dBH/dt ${\text{dB}}_{H}/\text{dt}$ Spikes During Geomagnetic Storms

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Variations in the solar wind, particularly those associated with interplanetary coronal mass ejections (ICMEs) and high‐speed streams (HSSs), drive geomagnetic disturbances that produce rapid changes in the ground magnetic field. These variations, commonly quantified by the time derivative of the horizontal magnetic field dBH/dt $\left({\text ...

Medium‐Scale Traveling Ionospheric Disturbances Induced by Secondary Gravity Waves Associated With Record‐Breaking Heavy Rainfall in August 2021 Over Kyushu, Japan

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract This study reconstructs a multistep gravity wave (GW) pathway, from the generation of primary GWs by deep convection in the troposphere to the generation of secondary GWs that drive semi‐concentric medium‐scale traveling ionospheric disturbances (MSTIDs) in the ionosphere, during the record‐breaking heavy rainfall over Kyushu, Japan, in August

All Ionospheres are not Alike: Reports from other Planets [PDF]

, 1995
Our understanding of planetary ionospheres made some progress during the last four years. Most of this progress was due to new and/or improved theoretical models, although some new data were also obtained by direct and remote sensing observations.

The Response of the Martian Ion Precipitation to Extreme Solar Events

The Astrophysical Journal
Ion precipitation is a major driver of sputtering on Mars, yet its behavior under extreme solar wind conditions remains poorly characterized. Using MAVEN observations, we analyze 124 extreme solar wind events from 2014 to 2018 together with a unique ...

Cosmic Ray Anisotropy Generated by the June 22nd 2015 Interplanetary Events

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract On 22 June 2015, the near Earth interplanetary space was perturbed by a series of high‐speed streamers and interplanetary coronal mass ejections associated with an active region and two low‐latitude coronal holes. The interaction of these disturbances gave rise to the complex solar wind structure observed at 1 au.

Assimilating GNSS Airborne Radio Occultation Bending Angles With MPAS–JEDI During a Sequence of Atmospheric Rivers

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract Global Navigation Satellite System (GNSS) airborne radio occultation (ARO) observations, collected during Atmospheric River Reconnaissance (AR Recon) campaigns, enhance AR sampling beyond traditional dropsondes. Assimilating ARO bending angles requires a forward operator accounting for ARO geometry and proper integration in a data assimilation

Towards a precise modelling of transport processes in planetary ionospheres: photoelectrons, magnetospheric electrons and protons

, 2008
session C13Numerical simulations of planetary ionospheres (Earth, Mars, Venus and Titan) using Boltzmann's kinetic formalism have proved their efficiency in interpreting multi-instrumental data sets. We present now the last evolution of the Trans-* codes

Temperatures of Jupiter’s Upper Atmosphere: The Role of the Planetary Magnetic Field

The Astrophysical Journal Letters
The primary source of heating in the upper atmospheres (thermospheres) of giant planets has been the subject of long debate. The conundrum (or “energy crisis”) consists in observed thermosphere temperatures at low and midlatitudes exceeding values ...
