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 ...

Height‐Dependent Sensitivity of Cloud Scales to Surface Temperature Anomaly Observed by Active Satellites

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract As a key macrophysical property, cloud horizontal scale plays a critical role in cloud radiative effect (CRE), precipitation and convective structures. Until now, however, how cloud scales vary with surface temperature anomaly and their subsequent impacts on CRE and precipitation remains unclear.

Hierarchical Testing of a Hybrid Machine Learning‐Physics Global Atmosphere Model

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Machine learning (ML)‐based models have demonstrated high skill and computational efficiency, often outperforming conventional physics‐based models in weather and subseasonal predictions. While prior studies have assessed their fidelity in capturing synoptic‐scale atmospheric dynamics, their performance across timescales and under out‐of ...
