Across North America Tracer Experiment (ANATEX). Volume 3. Sampling at tower and remote sites. Technical memo

The Across North America Tracer Experiment (ANATEX) was designed to provide a comprehensive data base for assessing the performance of long-range transport and diffusion models. Three distinct perfluorocarbon tracers (PMCH, oPDCH, and PTCH) were released simultaneously for a 3-h duration every 2 1/2 days from 2 sites; PTCH from Glasgow, Montana, and oPDCH and PMCH (every fifth day) from St. Cloud, Minnesota for the 84-day period January 5, 1987 through March 29, 1987. The report describes the experimental design of the sampling programs at the tower and remote sites, discusses the measured data and how they were analyzed and quality assured, summarizes data characteristics, discusses data use, and presents complete data tables for both tower and remote sites. The report also describes the characteristics, format, and accessibility of data sets created from the data analysis.
