During the first three months of 1987, two chemically-inert perfluorocarbon tracer gases were released near ground level every 2.5-days from two sites in central North America and sampled for 24-hour periods at 77 surface sites across central and eastern North America. The source-receptor distances ranged from less than 30 km to 3000 km. These Across North America Tracer Experiment (ANATEX) data from the 66, 3-h releases serve as a unique evaluation data set with which to evaluate the long-range transport and diffusion simulations of regional atmospheric models and to establish a range of uncertainty for various model genres.
