This study presents the first model intercomparison of aerosol-cloud-turbulence interactions in a controlled cloudy Rayleigh-Bénard Convection chamber environment. We analyzed simulated cloud chamber-averaged statistics of microphysics and thermodynamics under steady-state conditions at varying aerosol injection rates. Our results demonstrate that all models qualitatively capture observed trends in droplet number concentration, mean radius, and droplet size distributions at both high and low aerosol injection rates. However, significant differences in magnitude among models are also observed, highlighting the need for further investigation into the mechanisms driving these variations. These findings underscore the importance of cloud chamber experiments for validating and improving cloud microphysical parameterizations, which are crucial for enhancing the accuracy of cloud representation in weather and climate predictions.
