Assessing Aerosol Wet Removal Efficiency in Conventional and Multiscale Modeling Framework Configurations of the Community Earth System Model

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Aerosol particles play a crucial role in the global climate by absorbing and scattering radiation and influencing cloud properties. This study explores the role of resolved convection on precipitation and subsequent removal by wet deposition of aerosol in the Community Earth System Model (CESM2.1.0) by comparing two configurations with ...

Interpretable Machine Learning‐Based Radiation Emulation for ICON

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract The radiation parameterization is one of the computationally most expensive components of Earth system models (ESMs). To reduce computational cost, radiation is often calculated on coarser spatial or temporal scales, or both, than other physical processes in ESMs, leading to uncertainties in cloud‐radiation interactions and thereby in ...

Causal Evidence that Rotational Moisture Advection is Critical to the Superparameterized Madden–Julian Oscillation [PDF]

Journal of the Atmospheric Sciences, 2014
AbstractThe authors investigate the hypothesis that horizontal moisture advection is critical to the eastward propagation of the Madden–Julian oscillation (MJO). Consistent diagnostic evidence has been found in recent MJO-permitting global models viewed from the moisture-mode dynamical paradigm.

Simulation of orographic effects with a Quasi‐3‐D Multiscale Modeling Framework: Basic algorithm and preliminary results

Journal of Advances in Modeling Earth Systems, 2016
The global atmospheric models based on the Multi‐scale Modeling Framework (MMF) are able to explicitly resolve subgrid‐scale processes by using embedded 2‐D Cloud‐Resolving Models (CRMs).

A Decadal Hybrid GCM Simulation Using Deep‐Learning‐Based Cloud and Convection Parameterization Generalized to a Warm Climate

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 12, December 2025.
Abstract A critical challenge for machine‐learning (ML) parameterization in global climate models (GCMs) is to achieve stable, accurate simulations under climates not seen during training. Previous studies have demonstrated promising offline performance and year‐long online stability in aquaplanet simulations but have encountered difficulties in real ...

Evaluation of Community Atmosphere Model Version 6 and Its Super‐Parameterized Version in Simulation of Cloud and Radiation Using Satellite Observation

Earth and Space Science, Volume 12, Issue 10, October 2025.
Abstract Cloud plays a crucial role in modulating the energy budget of the earth‐atmosphere system. Cloud‐resolving models have been demonstrated to be capable of better simulating the microphysical processes within clouds. This study assesses the super‐parameterized version of Community Atmosphere Model Version 6 (SPCAM6) in simulating clouds ...
