Nitrogen Deposition in the Grand Tetons a Temporal and Spatial Perspective

摘要

The general trend, of decreasing sulfate and ammonium ion, which was observed at Centennial, WY, was also observed at other CASTNET sites in the Rocky Mountains such as Yellowstone National Park, Rocky Mountain National Park, and Gothic,CO. At the CASTNET sites in Mesa Verde National Park in Colorado and in Pinedale, Wyoming the concentration of nitrate is increasing with a statistically significant positive trend.
