Overview of Aerosols in the E3SM Version 3: New Model Features and Their Impacts

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Accurate and comprehensive representation of aerosols in Earth system models (ESMs) is critical for modeling radiative forcing and seasonal‐to‐decadal variability. With increasing computing power, detailed physical and chemical processes representing aerosols and their interactions with other components of the Earth system can be treated more ...

Tertiary‐Ozone‐Maximum‐Like Mesospheric Ozone Increases Driven by Solar Eclipses: Sensitivity Experiments on WACCM‐X

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Solar eclipses offer natural experiments to isolate the photochemical response of mesospheric ozone to solar radiation. Using the WACCM‐X model, we performed mechanism‐oriented sensitivity experiments for the 14 December 2020 eclipse to quantify the tertiary‐ozone‐maximum‐like (TOM‐like) response.

Replacing Tunable Parameters in Weather and Climate Models With State‐Dependent Functions Using Reinforcement Learning

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Weather and climate models rely on parameterizations to represent unresolved sub‐grid processes. Traditional schemes rely on fixed coefficients that are weakly constrained and tuned offline, contributing to persistent biases that limit their ability to adapt to underlying physics.

Unifying the QBO, MJO Shallow‐to‐Deep Convection Transitions, and Mesoscale Convective Systems

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract This study investigates Madden‐Julian Oscillation (MJO) convective structures to better understand how the Quasi‐biennial Oscillation (QBO) impacts MJO propagation. We find that during the QBO easterly (QBOE) phase, MJO events exhibit convective features that are highly favorable for propagation.

A dataset of Beijing MST radar horizontal wind fields at Xianghe Station in 2012

中国科学数据
The atmospheric horizontal wind is an essential parameter for studying atmospheric dynamic characteristics, processes, and dynamic coupling between the upper and lower atmosphere. MST (Mesosphere Stratosphere and Troposphere) radar plays a unique role in

Prescribing Zonally Asymmetric Ozone Climatologies in Climate Models: Performance Compared to a Chemistry‐Climate Model

Journal of Advances in Modeling Earth Systems, 2019
Three different methods of specifying ozone in an atmosphere‐only version of the HadGEM3‐A global circulation model are compared to the coupled chemistry configuration of this model.

Rapid HCl Production From Chlorine Oxidation Sustains Coastal Atmospheric Chlorine Cycling

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Hydrogen chloride (HCl) is a major tropospheric reservoir of reactive chlorine. In coastal environments, it is thought to primarily originate from acid displacement of particulate chloride (Cl−). Here we demonstrate that chlorine radical oxidation of volatile organic compounds dominates HCl formation (∼64%) at a polluted coastal site with ...

Analysis of the Charge Structure and Lightning Activity During a Severe Beijing Thunderstorm via an Innovative Balloon‐Borne 3D Electric Field Observation System

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract We developed an innovative balloon‐borne observation system based on China's BeiDou sounding platform that integrates a three‐axis electric field sensor for in‐cloud measurements of thunderstorm electrification. On 13 May 2025, this system was deployed during a severe convective storm over Beijing. In combination with multisource observations,

From Magma to Atmosphere: Halogen Fluxes During Volcanic Eruptions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Volcanic eruptions release significant quantities of volatile elements into the atmosphere and stratosphere. Plinian eruptions are particularly efficient at dispersing these elements due to their large magma volumes and high eruption columns.

Influence of Explicit Tropospheric VOC Chemistry on the Top‐Of‐Atmosphere Net Radiation Budget: Differences Between Two Preindustrial CESM2 Chemistry Configurations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract The representation of volatile organic compound (VOC) chemistry in earth system models directly impacts aerosol formation. Previous work shows explicitly representing VOC chemistry produces significant impacts on simulated climate compared to an implicit “SOAG scheme” that prescribes a bulk gas‐phase precursor to secondary organic aerosol (SOA)
