 abstract = {A size-resolved equilibrium model, SELIQUID, is
presented and used to simulate the size-composition distribution of
semi-volatile inorganic aerosol in an urban environment. The model
uses the efflorescence branch of aerosol behavior to predict the
equilibrium partitioning of the aerosol components between the gas
phase and a size-resolved aerosol population over the entire RH
domain. Predictions of SELIQUID are compared against size-resolved
composition measurements at different locations during the Southern
California Air Quality Study. Based on the modeling results, the
size distribution of sub-micrometer nitrate and ammonium can be
determined by thermodynamic equilibrium when the RH > 60%. In
cases where the RH < 60%, the assumption that all aerosol
particles are metastable liquid solutions may introduce
unacceptable errors. On the other hand, the equilibrium assumption,
in some cases at least, introduces errors in the calculation of the
coarse (particles with diameter <1 mum or so) nitrate and ammonium
that increase with particle size. Finally, the inclusion of crustal
species is important in modeling the size distribution of coarse
inorganic aerosols when the concentration of these species is high.
The effect of these crustal species can be complex and
counterintuitive. (C) 2002 Published by Elsevier Science Ltd.
