Into the Mist: Sea Spray Aerosol Molecular Composition, Viscosity, and Multiphase Chemistry
Abstract:
The phase state or viscosity of aerosols plays a crucial role in various atmospheric processes, including ice nucleation, water absorption, and heterogeneous
reaction kinetics. Despite its significance, limited research has explored the viscosity of sea spray aerosol (SSA), which represents the largest annual mass flux of naturally occurring aerosols globally. Combining online high-resolution mass spectrometry
aerosol composition measurements with particle bounce, my group studies the molecular drivers of SSA viscosity and its effects on multiphase oxidation processes. In this talk, I will highlight our efforts in determining (1) the viscosity and molecular composition
of SSA across distinct biologically-active periods of a phytoplankton bloom, (2) size-dependent SSA viscosity, and the role of cation–organic interactions driving differences in viscosity with particle size, and (3) viscosity impacts on the photochemical and
heterogeneous oxidation kinetics of plastic additives in SSA mimics in the presence of model photosensitizers.
