Layer: Visibility Condition (ID:14)

View In: Map Viewer

Name: Visibility Condition

Display Field: NAMEABBR

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: Visibility conditions use the difference between visibility (haze index) on mid-range days and the natural conditions. Condition categories (good, fair, poor) are based on the estimated five-year average of this value compared to NPS Air Resources Division benchmarks. Visibility values for each NPS area are the estimated or monitor-specific 5-year average of the haze index on mid-range days minus the natural visibility on mid-range days. A result greater than 8 dv is assigned a Poor condition. A result from 2–8 dv is assigned Fair condition. A Good condition is identified when the result is less than 2 dv. See NPS air quality analysis methods for more information: https://www.nps.gov/articles/air-analysis-methods-latest.htm.
