A three‐dimensional, size‐resolved and chemically resolved aerosol model is developed. Gas‐to‐particle conversion is represented by dynamic mass transfer between the gas and aerosol phases. Particle‐phase thermodynamics is computed by a new thermodynamic model, Simulating Composition of Atmospheric Particles at Equilibrium 2. The aerosol model is applied to simulate gas and aerosol behavior in the August 27–29, 1987, episode in the South Coast Air Basin of California. The assumption that volatile inorganic species such as NH 4 NO 3 are at instantaneous, local equilibrium is examined.
