The potential impact of model horizontal resolution on the simulation of atmospheric cloud radiative effect in CMIP6 models

Abstract

Key points 1. Simulations of atmospheric cloud-radiative effect (ACRE) in 54 CMIP6 models are evaluated against the satellite-based observational data. 2. The performance of ACRE simulations is sensitive to the model horizontal resolution used. 3. The finer resolution models generally produce a better performance of ACRE simulations, especially over the cold tongues where shallow stratocumulus clouds prevail.
