Linking Air Quality and Watershed Models
Authors: Krish Vijayaraghavan and Ralph Morris
Atmospheric deposition is often a major component of pollutant loading to sensitive watersheds and ecosystems. However, the models used to track the fate of pollutants in the atmosphere and in watersheds have different features and are run at varying spatial and temporal scales with diverse chemical constituents and model inputs. This paper discusses the issues that need to be considered when integrating information from air quality and watershed/ecosystems models to address the impacts of sulfur, nitrogen and mercury deposition on ecosystems.
