DOIAbstract
Marine aerosol can impact atmospheric radiative balance and cloud formation. The formation mechanisms, growth pathways, and composition of ultrafine (<100 nm diameter) marine aerosol formed through secondary processes generally remain uncertain. Here, we present measurements of the composition of ultrafine secondary marine aerosol (SMA) during the Sea Spray Chemistry and Particle Evolution (SeaSCAPE) experiment, conducted at Scripps Institution of Oceanography in summer 2019. SMA was produced through the equivalent of one day of hydroxyl radical exposure to gaseous precursors emitted from coastal sea water from Scripps Pier in La Jolla, CA. The composition of ultrafine SMA was measured using Thermal Desorption Chemical Ionization Mass Spec...
