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.

Understanding and Anticipating Anomalous Surface Impacts During Large‐Scale Regimes

Meteorological Applications
Weather regimes describe the large‐scale atmospheric circulation in the mid‐latitudes in terms of a few circulation states that modulate regional surface weather conditions on time scales of multiple days to a few weeks.

Model Sensitivities of Biomass‐Burning Aerosol Chemical Aging, Sulfate Formation, and Cloud Droplet Activation in the Southeastern Atlantic Using CESM and E3SM

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Biomass‐burning smoke drives large uncertainty in climate projections of the Earth's radiative balance. This is due to the chemical and physical evolution of smoke and its impact on clouds and radiation. Here we focus on the southeastern Atlantic region and its inflow of African biomass‐burning smoke during August 2017.

A Deep Learning Model of Lightning Stroke Density

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Lightning plays a crucial role in the Earth's climate system; however, existing parameterizations for use in forecasting and earth system models show room for improvement in capturing spatial and temporal variations in its frequency. This study develops deep learning‐based parameterizations of lightning stroke density using meteorological ...

Atmospheric River Climatology for the South Atlantic Basin Using an Image Processing‐Based Methodology

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Atmospheric Rivers (ARs) are narrow regions of extratropical water vapor transport, situated in the lower troposphere. They are responsible for a large proportion of poleward vapor transport from the tropics to the midlatitudes. Although ARs are known to cause devastating floods when encountering topography, they are a crucial source of water ...

Global Modeling of Atmospheric Amines: Sources and Sinks

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Atmospheric amines (methylamine, MMA; dimethylamine, DMA; and trimethylamine, TMA) are critical to new particle formation, air quality, and climate, yet an integrated global cycling framework remains absent. This study develops a global emission inventory that integrates six source categories spanning anthropogenic sources (agriculture ...

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

A New Lidar‐Based Observational Estimate for a Short‐Term Longwave High‐Cloud Feedback

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract High clouds play a substantial role in modulating the Earth's top‐of‐atmosphere radiative energy budget. Models project that changes in high‐cloud altitude and area in response to warming will have a net warming effect within the tropics. Yet, to our knowledge, a robust global observational constraint of a short‐term cloud feedback associated ...

Impact of a Stratocumulus Scheme on Clouds and Feedbacks in MIROC7

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Marine stratocumulus (Sc) clouds exert a strong cooling effect on climate by reflecting solar radiation, yet many climate models underestimate their amount and cause uncertainty in equilibrium climate sensitivity (ECS). Herein, we show that incorporating a physically based Sc parameterization into the seventh version of the Model for ...

Quantifying the Competing Roles of Global Warming and the Strengthened Siberian High in Modulating Cold Extremes Over China

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Despite global warming, China continues to experience record‐breaking cold extremes. However, the extent to which internal atmospheric circulation variability offsets anthropogenic warming effects on cold extremes remains poorly quantified. Here, a nonstationary GEV is used to quantify the relative influences of anthropogenic warming and the ...
