Aerosol–cloud–radiation interactions have significant influences on natural climate variability and are also one of the largest uncertainties in the estimate of anthropogenic climate forcing. This session seeks presentations of recent research work that advances the understanding of how various aerosol–cloud interactions impact the local and global radiative energy budget, as well as how aerosol–radiation interactions affect and are affected by cloud systems, global circulation patterns, and climate. We welcome discussions related to i) how microphysical interactions between aerosol and cloud modulate the cloud radiative properties and surface and/or atmosphere energy budgets; ii) how the direct and semidirect radiative effects modify mesoscale and synoptic-scale weather systems and climate, including, but are not limited to, wave systems, monsoons, tropical cyclones, and mesoscale convective complexes; and iii) novel measurement (remote sensing and in situ) and modeling techniques to quantify the impacts of aerosol–cloud–radiation interactions.
