Name: Wet Nitrogen Condition
Display Field: NAMEABBR
Type: Feature Layer
Geometry Type: esriGeometryPoint
Description: Nitrogen conditions use the nitrogen portion of wet nitrate and ammonium deposition. Condition categories (good, fair, poor) are based on the estimated five-year average of this value compared to NPS Air Resources Division benchmarks. Deposition values for each NPS area are the maximum estimated or monitor-specific 5-year average of wet nitrogen deposition. Condition assessments rely on maximum estimated values to more conservatively characterize ecosystem sensitivity in parks. Wet deposition greater than 3 kg/ha/yr is assigned a Poor condition. Wet deposition from 1–3 kg/ha/yr is assigned Fair condition. A Good condition is identified when wet deposition is less than less than 1 kg/ha/yr. Condition adjustments: Nitrogen deposition condition is adjusted based on results from national assessment reports that identified ecosystems and resources at risk to nitrogen enrichment in national parks.
