This paper gives overviews of a sophisticated one-dimensional land surface model (SOLVEG) and a new particle dry deposition scheme for chemical transport models (CTMs) developed by the authors for assessment of the effects of aerosols on vegetation. The current major particle dry deposition schemes for CTMs are reviewed to examine the issue of less prediction accuracy in deposition velocity of sub-micron particles. The authors’ new particle dry deposition scheme overcomes the issue by including state-of-the-art knowledge based on SOLVEG simulations and providing better estimations of deposition velocity in this size range. As an example of regional scale analysis using this new scheme, simulation results of atmospheric black carbon (BC) onto forest areas in Eastern Asia are demonstrated.Our studies presented in this paper show that the land surface model developed by the authors is effective to evaluate the impacts of aerosols on the terrestrial biosphere.
