Abstract
A multiscale modeling system that includes a global model and a nested continental model is applied to simulate the global
cycling of atmospheric mercury and its fate and transport over North America. The models
show satisfactory performance with a coefficient of determination of 0.81 for mercury wet deposition over North
America. The models are used to estimate source attribution of mercury deposition in the United States. On
average, 73% of mercury deposited in the contiguous United States is calculated to originate from the global
background.
