The 2015 Gordon Research Conference (GRC) on Radiation and Climate will present research on physical processes relevant to climate, particularly those in which the interactions between radiation, clouds, aerosols, and precipitation play a major role. The Conference will feature talks highlighting the challenges in understanding these processes, modeling them, and ascertaining their impacts on cloud and aerosol feedbacks and/or rapid adjustments and the surface radiation budget. A list of preliminary session topics and speakers will be available by December 1, 2014.
