Cross APpalachian Tracer EXperiment (CAPTEX) Information

Cross APpalachian Tracer EXperiment (CAPTEX) was a series of 3-hour perfluorocarbon tracer releases; 4 releases from Dayton,OH (39.80N 084.05W) on Sep. 18, Sep. 25, Oct. 02, & Oct. 14 1983, and 2 releases from Sudbury, ONT (46.62N 080.78W) on Oct. 26 & Oct 29 1983.

Sampling sites were arrayed in arcs, at approximately 100-km intervals, 300 km to 1100 km from the Dayton release point; 62 sites in the U.S. and 24 in Canada and took either 3-hour or 6-hour samples, depending on the distance from the release point.
