A spatially refined monitoring based study of atmospheric nitrogen deposition

Marner, B.B. / Harrison, Roy M.

AbstractAtmospheric concentrations of ${NO}_{2}$ , ${HNO}_{3}$ , ${NH}_{3}$ , aerosol ${NH}_{4}^{+}$ and ${NO}_{3}^{-}$ , and the bulk deposition of ${NH}_{4}^{+}$ and ${NO}_{3}^{-}$ were measured for two years at ten sites around the West Midlands, UK. Eight of these sites were spread across the $125 {km}^{2}$ Lichfield nitrate vulnerable zone (NVZ). The measured data were interpolated across the area, and by applying land-use specific deposition velocities to the airborne concentrations, seasonal N deposition fluxes to the NVZ were estimated. There was a large spatial variation in deposition flux, driven mainly by land-use, but also by measured concentration gradients. Spatially averaged total flux exhibited a seasonal pattern; peaking in spring-summer. Each measured component contributed a substantial fraction of the total flux, but the importance of each varied seasonally. Oxidised-N and reduced-N fluxes were relatively equal. Annual average flux was approximately $20 kg N {ha}^{- 1} {yr}^{- 1}$ .
