Air Quality Estimates

These data sets provide estimates of air quality for each of the National Park Service (NPS) Inventory and Monitoring (I&M) Program parks. Ozone, wet deposition, and visibility parameters are included. Estimates are based on data from air quality monitors operated by the NPS, EPA, states, and others. The data are interpolated and mapped across the contiguous US and the specific value found at the center of each park is reported.
