Short summary

Excess reactive nitrogen deposition in the Greater Yellowstone Area is adversely affecting sensitive ecosystems. Source apportionment (SA) to quantify the contributions from important emission sectors/regions was conducted using CAMx–PSAT. Our results highlighted the importance of controlling reduced nitrogen, especially from agricultural activities in the Snake River valley. Uncertainties from NH₃ simulation, boundary conditions, and precipitation estimates in SA results were also discussed.
