Short summary

SIM-HOM (Sesquiterpene, Isoprene, and Monoterpene-derived Highly Oxygenated organic Molecules) is a mechanistic module simulating HOM formation from primary biogenic precursors. By providing quasi-molecular resolution, it quantifies the low-volatility compounds that drive secondary organic aerosol formation, robustly linking complex gas-phase chemistry to aerosol dynamics and climate impacts.
