Scientific paper

This paper presents observations of ammonia, nitric acid and size segregated chemically speciated aerosols above the canopy of a secondary successional deciduous forest in Indiana during spring. Average nitric acid concentrations range between 0.1-1 μg m-3 and vertical gradients from 1 to 9 ng m-3/m. The ammonia probability distribution indicates an average concentration of 0.8 μg m-3, although concentrations in excess of 2 μg m-3 are observed. Aerosol measurements indicate ammonium is largely confined to the accumulation mode (0.11.0μm) modes), and is present at mean concentrations of 1.2 μg m-3. Average dry deposition fluxes calculated from these measurements are: Nitric acid=0.38mg-Nm-2dy-1, ammonia=1.07mg-Nm-2dy-1, aerosol-nitrate=0.27mg-Nm-2dy-1, aerosol-ammonium=0.25mg-Nm-2dy-1. The total dry deposition nitrogen flux of over 1.9 mg-N m-2 dy-1 is approximately equal to the flux in precipitation as measured at NADP sites in the region.
