The project was designed to fill a critical gap in our ability to model atmospheric deposition to heterogeneous terrains. We developed an empirical modeling approach that predicts total deposition as a function of landscape features such as elevation, vegetation type, slope and aspect. We measured indices of total deposition to the landscapes of Acadia (121 km2) and Great Smoky Mountains (2074 km2) National Parks. Area-weighted deposition was found to be 50-70% greater than NADP (wet deposition) plus CASTNet (dry deposition) monitoring station estimates.The spatially-explicit deposition estimates derived from our LANDMod are a large improvement over what is currently available. The NPS can use our LANDMod to update deposition maps to reflect changes in reference (monitoring station) deposition and/or to reflect changes in vegetation. Work published as Weathers et al. 2006.
