摘要: We estimated the total inorganic fluxes of nitrogen (N), sulfur (S), chloride (Cl−, sodium (Na+, calcium (Ca2+, magnesium (Mg2+, potassium (K+ and hydronium (H+. The resistance deposition algorithm that is programmed as part CALMET/CALPUFF modeling system was used to generate spatially-distributed velocities, which were then combined with measurements urban rural concentrations gas particle species obtain dry rates. Wet rates for each determined from rainfall amounts available National Acid Deposition Program (NADP) monitoring network databases.
