“…The enrichment of Mg 2+ , K + , Ca 2+ , and S relative to seawater can be explained by contributions of re-suspended crustal minerals along with aerosols created by the atmospheric reactions of combustion NO x and SO x emissions with ammonia or sea salt (Campbell et al, 2002). Nanus et al (2003).…”

We estimated the total inorganic fluxes of nitrogen (N), sulfur (S), chloride (Cl − ), sodium (Na + ), calcium (Ca 2+ ), magnesium (Mg 2+ ), potassium (K + ) and hydronium (H + ). The resistance deposition algorithm that is programmed as part of the CALMET/CALPUFF modeling system was used to generate spatially-distributed deposition velocities, which were then combined with measurements of urban and rural concentrations of gas and particle species to obtain dry deposition rates. Wet deposition rates for each species were determined from rainfall concentrations and amounts available from the National Acid Deposition Program (NADP) monitoring network databases. The estimated total inorganic nitrogen deposition to the Tampa Bay watershed (excluding Tampa Bay) was 17 kg-N ha −1 yr −1 or 9,700 metric tons yr −1 , and the ratio of dry to wet deposition rates was ∼2.3 for inorganic nitrogen. The largest contributors to the total N flux were ammonia (NH 3 ) and nitrogen oxides (NO x ) at 4.6 kg-N ha −1 yr −1 and 5.1 kg-N ha −1 yr −1 , respectively. Averaged wet deposition rates were 2.3 and 2.7 kg-N ha −1 yr −1 for NH + 4 and NO − 3 , respectively.

“…Campbell et al [181] used EQUISOV JJ, a model that applied thermodynamics to compute equilibrium states for species distributed among a gas phase and multiple, internally mixed, size "bins" of an aerosol phase. The model was generally successful in predicting the distribution of nitrate, chloride, sulfate, and ammonium among fine and coarse particles collected over Tampa Bay, FL.…”

“…Similar approaches have been widely used to study gas/particle partitioning equilibrium [e.g., Pilinis and Seinfeld , 1987; Hayami and Carmichael , 1997; Ansari and Pandis , 1999; Jacobson , 1999; Moya et al , 2001, 2002; Fridlind and Jacobson , 2000; Fridlind et al , 2000; Campbell et al , 2002; Zhang et al , 2002; Trebs et al , 2005; Yao et al , 2006; Dasgupta et al , 2007; Goetz et al , 2008]. In contrast, our cases involve nonequilibrium gas/particle mass transfer.…”

[1] Simulating gas/particle mass transfer in three-dimensional (3-D) air quality models (AQMs) represents one of the major challenges for both hindcasting and forecasting. The lack of an efficient yet accurate gas/particle mass transfer treatment for aerosol simulation and forecast in 3-D AQMs warrants its development, improvement, and evaluation. In this paper, several condensation/evaporation schemes (e.g., the Bott, Trajectory-Grid (T-G), Walcek, and analytical predictor of condensation (APC)) are first tested in a condensation-only case. The APC and Walcek schemes are shown to be more accurate than the Bott and T-G schemes. The Walcek and the APC schemes are then incorporated into the Model of Aerosol Dynamics, Reaction, Ionization, and Dissolution (MADRID) to solve the gas/particle mass transfer process explicitly. The test simulations with MADRID are initialized with measurements available from three sites with representative meteorological and emission characteristics. The results are evaluated using benchmark based on the kinetic approach with 500-section for all cases and available measurements from two sites. The box MADRID tests have shown that the bulk equilibrium approach fails to predict the distribution of semivolatile species (e.g., ammonium, chloride, and nitrate) because of the equilibrium and internal mixture assumptions. The hybrid approach exhibits the same problem for some cases as the bulk equilibrium approach since it assumes bulk equilibrium for fine particles. The kinetic approaches (including the APC and Walcek schemes for the condensation/evaporation equations) predict the most accurate solutions. Among all approaches tested, the bulk equilibrium approach is the most computationally efficient, and the kinetic/Walcek scheme provides an accurate solution but is the slowest due to its requirement for a small time step. Overall, the kinetic/APC and hybrid/APC schemes are attractive for 3-D applications in terms of both accuracy and computational efficiency.Citation: Hu, X.-M., Y. Zhang, M. Z. Jacobson, and C. K.
