Improved Representation of Surface Emissivity Effects on Longwave Radiation in a Coupled Earth System Model

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Many Earth System Models (ESMs) approximate surface emissivity as constant over all wavelengths (broadband). This approximation misrepresents the spectral distribution of longwave (LW) flux and introduces error in the LW atmospheric heating rate.

Updated Interior Structure of Callisto From a Reanalysis of Galileo Data

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract The internal structure of Callisto has been a long‐standing question since the Galileo mission. Previous analyses suggested a largely undifferentiated interior. We present an updated interior structure for Callisto derived from a reanalysis of Galileo's Doppler tracking data using new signal processing techniques.

Wavelet-Based P-Wave Detection in High-Rate GNSS Data: A Novel Approach for Rapid Earthquake Monitoring in Tsunamigenic Settings

Sensors
Rapid and accurate detection of primary waves (P-waves) using high-rate Global Navigation Satellite System (GNSS) data is essential for earthquake monitoring and tsunami early warning systems, where traditional seismic methods are less effective in noisy

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.

The regional climate–chemistry–ecology coupling model RegCM-Chem (v4.6)–YIBs (v1.0): development and application [PDF]

Geoscientific Model Development
The interactions between the terrestrial biosphere, atmospheric chemistry, and climate involve complex feedbacks that have traditionally been modeled separately.

Exploring Antarctic Feedback Mechanisms Using Two‐Way Coupled Subglacial Hydrology and Ice Flow Modeling in the Siple Coast

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract The Siple Coast region of West Antarctica is known for its fast flowing, topographically unconstrained ice streams that evolve due to subglacial conditions. In this work, we analyze the nature of the Siple Coast subglacial hydrologic system and its interactions with the ice sheet using two‐way coupled subglacial hydrology and ice flow modeling.

Study of the Relationship Between Urban Microclimate, Air Pollution, and Human Health in the Three Biggest Cities in Bulgaria

Urban Science
Public health impacts of non-optimal temperatures and air pollution have received insufficient attention in Southeast Europe, one of the most air-polluted regions in Europe, simultaneously pressured by climate change.

Gravitational Stability of Hydrated SiO2 and Basaltic Crust in the Lower Mantle

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract We determined thermal equations of state of hydrated stishovite and CaCl2‐type SiO2 up to 100 GPa and 3,000 K to assess the gravitational stability of hydrated stishovite and basaltic crust in the lower mantle. Using machine‐learning based atomistic simulations, we examined three hydrogen dissolution mechanisms: hydrogarnet‐type, interstitial ...

Seismic Constraints of the 23 November 2025 Hayli Gubbi Eruption Sequence in Afar, Ethiopia

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract On 23 November 2025, the Hayli Gubbi volcano in Afar (Ethiopia) erupted in a massive explosion. We present the first seismic characterization using data from 13 regional seismological stations. Seismograms reveal signals consisting of a minute‐long precursor, a main eruptive phase, and secondary events hours later.
