The Aerosol Inorganics Model Project

Phase equilibrium models of inorganic aerosol systems of composition H+- NH4+- Na+-SO42- -NO3-- Cl--H2O. The models enable the distribution of water and ions to be calculated between liquid, solid and vapour phases for ambient conditions (temperature, relative humidity) specified by the user. Calculations of the activities of water and ions present in the aqueous aerosol
