Interactive Gas Chemistry for Enhanced Science Capabilities of the Energy Exascale Earth System Model Version 3

Journal of Advances in Modeling Earth Systems
Atmospheric chemistry plays a crucial role in Earth system models (ESMs), controlling atmospheric composition and radiative balance; it is highly interactive with the physical climate, biogeochemical cycles, and human systems.

Present-day correlations are insufficient to predict cloud albedo change by anthropogenic aerosols in E3SM v2 [PDF]

Atmospheric Chemistry and Physics
Cloud albedo susceptibility to droplet number perturbation remains a source of uncertainty in understanding aerosol–cloud interactions and thus both past and present climate states. Through the Energy Exascale Earth System Model (E3SM) v2 experiments, we

How Well Do CMIP6 Models Simulate the Influence of the West African Westerly Jet on Sahel Precipitation?

International Journal of Climatology, Volume 46, Issue 7, 15 June 2026.
Climate models generally reproduce the WAWJ and August peak but simulate its onset prematurely and too strongly relative to ERA5. CMIP6 simulations struggle to reproduce the jet–precipitation relationship in the Sahel and underrepresent associated moisture transports.

Historical and Projected Tropical Cyclone Characteristics in SPEAR Large Ensemble Simulations

Earth's Future, Volume 14, Issue 6, June 2026.
Abstract This study analyzes the climatology, variability, and key characteristics of tropical cyclones (TC) in future projections from the Seamless System for Prediction and EArth System Research (SPEAR) Large Ensemble, compared with historical simulations. TC genesis numbers are projected to significantly decrease, a trend that is partly explained by

Representation of atmosphere induced heterogeneity in land – atmosphere interactions in E3SM-MMFv2

Geoscientific Model Development, 2023
Abstract. In E3SM-MMF, where parameterizations of convection and turbulence are replaced by 2-D CRM, there are multiple options to represent land-atmosphere interactions. Here, we propose 3 different coupling strategies: 1) coupling of a single land surface model to the global grid (MMF), 2) coupling a single land instance directly to the embedded CRM (

Importance of Spatially Continuous Urban Surface Properties in Urban‐Resolving Earth System Modeling

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 6, June 2026.
Abstract Accurate representation of urban properties and processes at higher resolutions in global modeling systems is essential for advancing our ability to capture the complexities of urban systems and informing effective resilience strategies. However, the prescription of coarse global‐scale urban properties in most state‐of‐the‐art Earth system ...

Ocean Barrier Layers in the Energy Exascale Earth System Model

Geophysical Research Letters, 2019
Ocean barrier layers (BLs) separate the mixed layer from the top of the thermocline and are able to insulate the mixed layer from entrainment of cold thermocline water.

Attributing Upper‐Tropospheric Warm Biases in CMIP6 Models to Ice Cloud‐Radiation Interaction Deficiencies Over Tropical Oceans

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract We assess the impact of hydrometeor radiative effects on tropical and subtropical Pacific air temperature anomalies (TAA) using Coupled Model Intercomparison Project Phase 6 (CMIP6) model simulations and satellite data. CMIP6 models are grouped by their treatment of frozen hydrometeors: SON2 (explicit cloud and falling ice), SON1 (simplified),

Sensitivity of Anthropogenic Cloud Droplet Number Change to Preindustrial Emission Inventories and Physics Parameterizations

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Understanding the preindustrial (PI) to present‐day (PD) change in cloud droplet number concentration (ΔNd) is important to constrain the anthropogenic influence on clouds and aid future model projections. Perturbed parameter ensemble simulations of PI and PD conditions in the Energy Exascale Earth System Model (E3SMv3) reveal two locations ...
