Ozone Distribution Study
In Great Smoky Mountains National Park
This was a special study using ozone passive samplers at about 60 locations to determine the distribution of ozone pollution within the park. Volunteers did the bulk of the sampling during the summer. The product includes GIS map layers pin-pointing areas within the park where vegetation is most at risk from ozone exposure.
Study dates: May - Sept. with the core sampling from June 19 to August 28, 2000
Results of the interpolation mapping
From the processed data, detailed maps were created for seasonal ozone concentrations. Note how the model from the normal number of stations available has less detail in the park and predicts slightly higher ozone surrounding the park boundaries. There is an elevation gradient in ozone in that mountain tops see a larger average ozone concentration than low elevations.
