Cooling Earth by aerosol effects on shallow marine clouds 11am-12.30pm Thursday 29 Feb 2024 AEDT Adding fine aerosols to shallow marine clouds can lead to large cooling that exceeds the greenhouse gases-induced warming. Technology of production of fine sea spray aerosols has a tail of coarse aerosols, which is suspected to have a warming effect. However, satellite observations show that natural sea spray enhances cloud radiative cooling, and the maximum cooling requires an optimal combination of fine and coarse aerosol concentrations. Aircraft measurements of the effect of artificial sea spray validate the satellite measurements. One probable cause for the cooling effect of coarse sea spray is its hygroscopicity which slows down the evaporation of cloud droplets. Join this seminar online to hear from Professor Daniel Rosenfeld on his work investigating cooling Earth by aerosol effects on shallow marine clouds.

His research methodology primarily consists of in situ aircraft measurements, radar and satellite remote sensing, and cloud simulations. He served as a Lead Author of the 6th IPCC assessment in the chapter on water cycle changes. He holds numerous prestigious appointments across the world and has published over 275 papers and book chapters which are highly cited. Prof Rosenfeld is a Visiting Fellow of the ANU Institute for Climate, Energy and Disaster Solutions and is on the steering committee of the Cyclogenesis Project, which investigates how Tropical Cyclone energy and impacts can be modified using aerosols using a novel simulation tool. -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
