Temporal trajectories of wet deposition across hydro-climatic regimes: Role of urbanization and regulations at U.S. and East Asia sites

► Hydro-climatology drives inter- and intra-annual variability of wet deposition flux. ► Anthropogenic controls can homogenize wet deposition trajectories of NO3 and SO4. ► Stochastic simulations enabled evaluation of the relative importance of drivers. ► Results are useful in identifying locations that can benefit from strong regulations.
