CLICK HERE to view charts that represent data collected by U.S. E.P.A. during a program called "The Passive Ozone Network in Dallas" (POND Concept). It was a modeling opportunity with Community Involvement. The graphs are presented here to show the correlation between the Ogawa Passive Sampler and Real-Time monitors collocated at the sites indicated. A comprehensive paper, explaining in detail this program, was presented at the 31st Annual Air Pollution Workshop, Corvallis, Oregon on April 26-29, 1999. |
