Atmospheric equilibrium model of sulfate and nitrate aerosols—II. Particle size analysis

Abstract

Part I of this work presented a thermodynamic equilibrium model for the quantity, composition, and physical state of atmospheric sulfate/nitrate/ammonium aerosols. In this work we extend that model to include particle size. That is, given total nitrate and ammonium levels, relative humidity and temperature, and the distribution of sulfate by particle size, we calculate the equilibrium quantity, composition, and physical state of the aerosol as a function of particle size. The model provides an explanation for the differences in observed ambient sulfate and nitrate size distributions.
