Atmospheric total deposition of reactive N calculated by the TM4-ECPL model in Tg-N y−1 calculated based on different anthropogenic emission inventories. In parentheses the respective deposition fluxes over the oceans are provided. The estimate from the ACCMIP multi-model simulations (Lamarque et al. 2013a,b), from the PhotoComp simulations (Dentener et al. 2006) and from the Vet et al. (2014) for the year 2000 are provided for comparison. For the Vet et al. (2014) estimates number in parenthesis provides deposition on coastal and ocean systems. Non-marked (base case) simulations are done with N:C of 0.16 for combustion sources and sea-salt and dust components taken into account in ISORROPIA II; crosses (+) mark simulations as base case but with N:C ratio of 0.3 and stars (*) mark simulations as base case but without NOx-to-VOC dependence of N-SOA formation and neglecting sea-salt and dust aerosol components in the ISORROPIA II thermodynamic equilibrium model. &NOy=sum of NOx,HNO3, NO3p; NHx = sum of NH3,NH4+
