Altitude-dependent role of nitric acid in iodic acid-iodous acid nucleation: from marine boundary layer catalyst to upper troposphere core component

Abstract. With global sulfur emissions declining and concurrent marine iodine emissions rising, new particle formation (NPF) driven by iodic acid (HIO3) and iodous acid (HIO2) has become critical to global aerosol and cloud condensation nuclei (CCN) budget. However, the role of u...

Spontaneous ChlorineGeneration via Interfacial Oxidationof Chloride by O2 on Acidic Microdroplets

Abstract Reactive chlorine species significantly influence atmospheric chemistry, yet their sources remain inadequately defined. We have discovered a spontaneous formation pathway for substantial molecular chlorine (Cl2) from the oxidation of chloride (Cl–) through interfacial ox...
