Detecting an Ocean Inside Callisto With Geodetic Measurements From Europa Clipper and Juice

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Determining whether Callisto hosts a subsurface ocean, and the implications for material and energy transport through its hydrosphere, is of high interest to NASA's Europa Clipper and ESA's Juice missions. A recent reanalysis of Galileo magnetometer data strengthens the ocean hypothesis, but definitive confirmation awaits new measurements.

A GEO‐LEO Imager Data Set for Characterizing Rapid Changes of Global Aerosol Properties

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Aerosols, the ubiquitous small particulates in our atmosphere, have climate, air quality, and/or other impacts far from their original sources. The Dark Target Algorithm (DTA), originally developed for retrieving aerosol properties from satellite imagers in Low‐Earth Orbit (LEO), has been ported to imagers in Geostationary (GEO) orbit. Using a

Oxygen Ion Percentage Inferred From the Cutoff Frequencies of Ionospheric ELF Hiss Emissions

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract The lower cutoff frequency of hiss emissions observed in the ionosphere is controlled by local plasma composition and density. This study identifies 6,340 ionospheric hiss wave events based on observations from the China Seismo‐Electromagnetic Satellite (CSES‐01) from 1 August 2018 to 31 July 2020.

Structured Energy Conversion in Kelvin‐Helmholtz Instability

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract We present quantitative investigations of the energy conversion pathways—electromagnetic ϵEM $\left({{\epsilon}}^{EM}\right)$, fluid flow ϵf $\left({{\epsilon}}^{f}\right)$, and particle thermal ϵth $\left({{\epsilon}}^{th}\right)$ energies—within the Kelvin‐Helmholtz instability (KHI) observed by the Magnetospheric Multiscale mission. We find

Magnetic Field Disturbance Induced by the Enhanced Suprathermal Ring Current in the Magnetosphere of Saturn

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Saturn's ring current, which modulates the global magnetic field configuration, varies dynamically with hot plasma injections. However, quantifying transient magnetic field disturbances remains challenging in the absence of in situ measurements on Saturn's surface.
