A cross section of densely packed, atmospherically relevant, organic molecules on a model of sea spray aerosol. Pictured are water (blue), sodium ions (green) and organic molecules (magenta and white, where magenta are aliphatic chains and white are phosphate groups). The arrangement of molecules at the surface of sea spray aerosols influences both the chemical reactivity of those particles (implications include ground level ozone pollution) and the ability of the aerosols to form cloud droplets (implications include precipitation and freshwater shortages).
The chemistry of aerosols controls their ability to react and grow into cloud droplets.Image credit: Paesani Group, University of California, San Diego
