Abstract
The sensitivity of sulfate and nitrate deposition during a spring storm in the eastern United States to changes in SOx and NOx emissions is evaluated by performing simulations with the STEM-II acid deposition model. The proportionality between emission reductions and deposition is found to vary from the dry and wet processes. Dry deposition of sulfate and nitrate is proportional to SOx and NOx emissions, respectively. Liquid-phase production of sulfate is nonproportional to SOx and NOx emissions. Total domain-integrated liquid-phase production of sulfate decreases by 35% when SOx emissions are reduced by 50% and increases by 15% with a 50% lowering of NOx emissions. The smallest changes in sulfate wet deposition occur in those regions with large SO2 emissions, and those experiencing heavy precipitation. The results are found to be sensitive to how the boundary and initial conditions are treated in the emission reduction simulations, with larger nonlinearities occurring when the boundary conditions are held fixed.
