Field Evidence of New Particle Formation Assisted by Iodic Acid in Northern Coastal China
) and amines, contributes to coastal NPF under real atmospheric conditions. Iodine-containing clusters account for 3.3%, 17.7%, 15.5%, and 4.5% of the dimers in spring, summer, autumn, and winter, on average, respectively, and can reach up to 50%. Iodic acid also significantly improves the early growth and survival of newly formed particles, with the survival probability of particles being increased by up to 8-fold. Our ambient observational results highlight the crucial role of iodic acid in airborne aerosol production (secondary aerosol formation) within mixed marine-continental atmospheres.
