Short summary
Iodic acid (IA) particles are frequently observed in the upper troposphere and lower stratosphere (UTLS), yet their formation mechanism remains unclear. Nitric acid (NA) and ammonia (NH3) are key nucleation precursors in the UTLS. This study investigates the IA–NA–NH3 system using a theoretical approach. Our proposed nucleation mechanism highlights the crucial role of NA in IA nucleation, providing molecular-level evidence for the missing sources of IA particles in the UTLS.
