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. See NPS air quality analysis methods for more information: https://www.nps.gov/articles/air-analysis-methods-latest.htm.
