Aerosol-cloud interactions have significant influences on natural climate variability and are also one of the largest uncertainties in the estimate of anthropogenic climate forcing. A variety of aerosol-cloud interaction mechanisms and processes have been identified over the past few decades. This session seeks to advance the understanding of how various aerosol-cloud interactions impact the local and/or global radiative energy budget and consequent implications. We welcome discussion forum related to i) how microphysical interactions between aerosol and cloud modulate the cloud radiative properties and radiative effects (e.g., Twomey and lifetime effect); how the relative position of aerosol and cloud (e.g., aerosol above, below and inside clouds) influences the radiative energy distribution; and iii) novel measurement (remote sensing and in situ) and modeling techniques to quantify the impacts of aerosol-cloud interactions on radiation.
