Constraining the Stratospheric Sulfate Budget in Global Models: Insights From In Situ OCS Measurements During 2023 SABRE and Comparison With Satellite, Balloon and Surface Data

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract In situ carbonyl sulfide (OCS) measurements from the Stratospheric Aerosol processes, Budget and Radiative Effects (SABRE) 2023 airborne campaign are used to evaluate the sulfate budget in the Arctic stratosphere during boreal winter. The strong correspondence between these measurements and remote retrievals from the Atmospheric Chemistry ...

Abnormally Large Magma Flux Does Not Lead to Eruption in Subduction Zone Calderas: The 2022–2023 Episode of Uplift of Aniakchak Crater (Aleutians)

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Observations of ground deformation provide insights on the triggering mechanisms of eruptions. At Aniakchak Crater (Aleutians) InSAR measured ∼ ${\sim} $72 cm of uplift in less than 7 months between 2022 and 2023. The uplift can be explained by the inflation of a point pressure source at a depth of 3.2 km.

Tracking Subsurface Changes via Frequency Shifts in Volcanic Tremor Spectral Lines: Observations From Mt Etna

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Episodes of volcanic tremor provide valuable insights into the dynamics of subsurface processes at active volcanoes. Previous studies have suggested that evolving tremor properties may relate to changes in the stress conditions of the plumbing system. However, a strong causative link has remained elusive.

Extreme Potomac Floods at Washington D.C. During the Past 500 Years

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Washington D.C. faces one of the highest 100‐year flood risks of any major city along the U.S. East Coast. In addition to storm‐surge inundation during hurricanes and nor'easters, water‐level observations for Washington are strongly skewed by major floods on the Potomac River.

Southern Ocean Sulfate Aerosol Sources Quantified From Sulfur Isotopes in Antarctic Ice Cores

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The Southern Ocean has emerged as a key region for constraining aerosol‐climate interactions due to its relatively low anthropogenic influence. Sulfate is an important aerosol over the Southern Ocean, and models suggest dimethyl sulfide (DMS) is the largest source of sulfate during summer.

Crustal Flow‐Driven Plateau Growth and Expansion Front in NE Tibet: Insights From High‐Resolution Attenuation Tomography With High‐Density ChinArray Lg Data

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The Northeastern (NE) Tibet, as the front of plateau growth, widely absorbs northeastward extrusion, leading to significant uplift and forming a basin‐mountain tectonic framework. However, it remains unclear how the crust of NE Tibet deformed in response to the far‐field effects of the India‐Eurasia collision.

Change in Tropical Cyclone Efficiency Under Different ENSO Conditions in the Western North Pacific Ocean

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Tropical cyclones (TCs) can be considered as Carnot heat engines, where thermodynamic efficiency depends on the sea surface temperature (SST) and TC outflow temperature (To) in the upper atmosphere. This study investigates how TC efficiency in the western North Pacific (WNP) Ocean varies under different El Niño‐Southern Oscillation (ENSO ...

Mid‐Proterozoic Transient Oxygenation Events Linked to Enhanced Continental Chemical Weathering: Evidence From Carbonate Lithium Isotopes

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Potential drivers disrupting mid‐Proterozoic (∼1.8–0.8 Ga) environmental stasis remain poorly constrained. Here we examined carbonate Li isotopes from the ∼1.44 Ga Tieling Formation, North China, to evaluate the effects of continental chemical weathering on coeval oxygenation.

Influence of Surface Aerosol Injection on Stratocumulus‐to‐Cumulus Transition: Cloud‐Surface Coupling and Background Aerosol Concentrations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 2, 28 January 2026.
Abstract The influence of surface aerosol injection on the stratocumulus‐to‐cumulus transition (SCT) is explored using large‐eddy simulations. We examine how cloud‐surface coupling (or the strength of the marine boundary layer (MBL) stratification that limits vertical turbulent mixing and convection) impacts the vertical transport of aerosols, and how ...
