RCEMIP-ACI: Exploring Aerosol-Cloud Interactions in Radiative-Convective Equilibrium
The Radiative-Convective Equilibrium Model Intercomparison Project – Aerosol-Cloud Interactions (RCEMIP-ACI) is a multi-model initiative designed to deepen our understanding of how aerosols influence cloud properties and atmospheric circulation. By leveraging the idealized Radiative-Convective Equilibrium (RCE) framework, this project provides a robust and controlled environment for studying cloud-aerosol interactions under varying sea surface temperature (SST) conditions. This MIP was conducted under the auspices of GEWEX (Global Energy and Water Exchanges; Link).
RCEMIP-ACI expands upon the original RCEMIP protocol by incorporating aerosol perturbations at three distinct concentrations (20, 200, and 2000 cm⁻³) while excluding direct aerosol-radiation interactions. This approach allows us to systematically investigate the equilibrium response of clouds, precipitation efficiency, convective aggregation, and large-scale circulation to aerosol changes. Simulations from 11 different models were submitted to this project, and the dataset is presented in this paper: Link. Please cite this paper when using the RCEMIP-ACI dataset.
