First Results of a New Inversion Tool for Thermospheric Neutral Mass Density Computations During Severe Geomagnetic Storms

open access: yesAGU Advances, Volume 7, Issue 3, June 2026.
Abstract In Low Earth Orbit (LEO), atmospheric drag is the dominant source of trajectory prediction error below approximately 700 km altitude, primarily due to inaccuracies in thermospheric density models. This work presents a method for temporally deconvolving Energy Dissipation Rates (EDRs) to produce single‐satellite density estimates, which can be ...

Multi‐Scale Rate‐ and Roughness‐Dependent Frictional Constitutive Law and Dynamic Earthquake Sequence Simulation

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract The physical mechanisms that govern the multi‐scale source properties of earthquakes, such as fracture energy scaling, where the dynamic energy dissipation of earthquakes scales with fault slip, remain debatable. We introduced the rate‐ and roughness‐dependent friction (RRF) law which accounts for the multi‐scale roughness evolution of the ...

Subsurface Ventilation Processes in a Wind‐Driven Coastal System: Insights From the Gulf of Oristano (Italy)

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract High‐resolution, year‐long observations (2023–2024) were conducted in the Gulf of Oristano, a shallow semi‐enclosed basin on the western coast of Sardinia, to address the scarcity of sustained in situ measurements resolving sub‐seasonal coastal processes in the Mediterranean.

On the Detection of Low‐Frequency Planetary Radio Emission With an Orbiting Interferometer

open access: yesRadio Science, Volume 61, Issue 6, June 2026.
Abstract The magnetized planets of the outer Solar System produce kilometric radio emissions at very low frequencies (<1 ${< } 1\,$MHz). They reveal the planetary magnetic dynamics and their interaction with the solar wind. Those radio emissions can also serve as a proxy for interplanetary space weather monitoring.

What Observations Would an Energetic Neutral Atom Imager Have Made During the Voyager 2 Flyby of Uranus?

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We present large‐scale simulations of energetic neutral atom (ENA) emissions at Uranus from a spacecraft viewpoint. Models of magnetic field, extended hydrogen exosphere, moon‐sourced neutral tori, and proton radiation belt are implemented into a simulator to evaluate the production of ENAs for L $L$ = 1–15.
