Title: "Cloud chemistry in the lab: tracking the pathways of brown carbon formation"

Abstract: Cloud droplets and aqueous aerosol particles can scavenge water-soluble gases from the atmosphere, where they may then react together to form larger, light-absorbing “brown carbon” molecules that impact climate. Chemists often use bulk liquid simulations to characterize the formation and sinks for cloud-born molecules. However, bulk liquid simulations tend to miss surface processes, multiphase effects, and chemistry driven by droplet evaporation. This talk will describe recent aerosol-based lab measurements that find fast brown carbon oligomer production in methylglyoxal-containing aqueous aerosol particles exposed to methylamine gas.
