Derivation of the stoichiometric coefficient of water (νw) to account for water uptake by atmospheric aerosols
Abstract. In this work we derive the effective stoichiometric coefficient of water (vw), introduced by Metzger and Lelieveld, 2007 (ML07), from first principles. We give examples of the application of vw in CPU efficient computations of the Deliquescence Relative Humidity (DRH) and the water uptake of atmospheric aerosols, being important parameters in atmospheric chemistry and climate modeling. We show that the application of vw in a gas/liquid/solid aerosol equilibrium partitioning model (EQSAM3) leads to results that are in excellent agreement with those of widely used thermodynamic (reference) models (E-AIM and ISORROPIA2) for various single salt solutions (NaCl, NH4NO3, (NH4)2SO4, NH4HSO4, NaHSO4) and the corresponding mixed solutions (including (NH4)3H(SO4)2 and Na3H(SO4)2), notwithstanding the distinct different theoretical and numerical concepts on which these models are based.
