    The main nucleating vapor in the atmosphere is thought to be sulfuric acid (H2SO4), stabilized by ammonia (NH3). However, in marine and polar regions, NH3is generally low, and H2SO4is frequently found together with iodine oxoacids [HIOx, i.e., iodic acid (HIO3) and iodous acid (HIO2)]. In experiments performed with the CERN CLOUD (Cosmics Leaving OUtdoor Droplets) chamber, we investigated the interplay of H2SO4and HIOxduring atmospheric particle nucleation. We found that HIOxgreatly enhances H2SO4(-NH3) nucleation through two different interactions. First, HIO3strongly binds with H2SO4in charged clusters so they drive particle nucleation synergistically. Second, HIO2substitutes for NH3, forming strongly bound H2SO4-HIO2acid-base pairs in molecular clusters. Global observations imply that HIOxis enhancing H2SO4(-NH3) nucleation rates 10- to 10,000-fold in marine and polar regions.
