Joint Session 8 Impacts of Aerosol–Cloud Interaction on Radiation

Monday, 8 January 2018: 10:30 AM-12:00 PM
Room 12A (ACC) (Austin, Texas)
Hosts: (Joint between the 10th Symposium on Aerosol-Cloud-Climate Interactions; and the 20th Conference on Atmospheric Chemistry )

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. This session seeks presentations of recent research work that advances the understanding of how various aerosol–cloud interactions impact the local and/or global radiative energy budget and consequent implications for climate change. We welcome discussion forums related to i) how microphysical interactions between aerosol and cloud modulate the cloud radiative properties and radiative effects (e.g., Twomey and lifetime effect), ii) 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.
