Beyond the Electrostatic Approach: Numerical Simulations of Martian Ionospheric Irregularities

AGU Advances, Volume 7, Issue 5, August 2026.
Abstract 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. However, the Mars Atmosphere and Volatile EvolutioN (MAVEN) observations reveal that the Martian ionospheric ...

Saturation Effects in Narrowband Resonance Lidar Measurements, Part 1: Theoretical Consideration of Sodium, Iron, and Helium Lidar Systems

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Atmospheric resonance lidars targeting metallic species in the mesosphere and lower thermosphere have yielded insights into the dynamics of the middle and upper atmosphere for over 50 years. Recently, the technique has been extended to the metastable helium layer, which reaches up to 1,000 km or above.

Investigating the Leptokurtotic Nature of Low‐Latitude GNSS Scintillations With a Multiscale Approach

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract We investigate the statistical nature of Global Navigation Satellite System (GNSS) signal fluctuations through the multiscale analysis of a strong scintillation event recorded at the Ionospheric Observatory of the Luigi Broglio Space Center in Malindi, Kenya.

Self‐Limiting of Artificial Electron Radiation Belts: Evidence From the Starfish Prime High‐Altitude Nuclear Explosion

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The 1962 Starfish Prime high‐altitude 1.4‐megaton nuclear detonation injected large amounts of fission‐produced energetic electrons into the inner magnetosphere (L = 1.12), creating an intense artificial radiation belt that persisted for years. In this study, we revisit historical data from this unprecedented event to investigate the potential

A Semi‐Resolved VOF‐DEM Coupling Method for Bedload Transport of Non‐Spherical Particles

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Bedload transport of coarse sediments involves complex particle‐flow interactions that govern sediment motion and bed surface evolution. In this study, a semi‐resolved CFD‐DEM method is developed to simulate bedload sediment dynamics, in which the background fluid information for each particle is calculated using a Gaussian kernel function ...

Incorporating coherent multiple scattering into modelling of small‐q scattering data

Journal of Applied Crystallography, Volume 59, Issue 4, Page 1327-1331, August 2026.
A new example for coherent multiple scattering is presented that confirms the Teubner–Strey model with its surface scattering for porous materials.In a recent paper [Frielinghaus & Gommes (2025), J. Appl. Cryst.58, 1553–1570] the appearance of coherent multiple scattering was discussed, whereby surface scattering takes over against the classical bulk ...
