Abstract - ANATEX was conducted during the first 3 months of 1987 with routine emissions of tracers, regardless of the synoptic conditions, from two sources separated by about 1000 km. Ground-level tracer measurements were made at "primary" sites up to 3000 km from the sources and at "remote" sites for hemispheric coverage. Tracer measurements were also made from aircraft flying within about 500 km of the sources and on towers located along a ground-level sampling arc (Volumes II and III).  Three months of sampling data provide a comprehensive data base for evaluating the accuracy and reliability of the transport and dispersion aspects of long-range models.  Since a different and unique tracer was released from each source site, the sampling data can be used to demonstrate the ability of models to separate the effects of local and distant sources.  Further, because these data are on the regional scale, covering the entire eastern United States and Canada, it is possible to characterize the meteorological influence on regional transport.
