The 1981 Idaho Field Experiment was conducted in southeast Idaho over the Upper Snake River Plain. Nine test-day case studies were conducted between July 15 and 30, 1981. Releases of SF/sub 6/ gaseous tracer were made for 8-hour periods from 46 m above ground. Tracer was sampled hourly, for 12 sequential hours, at about 100 locations within an area 24 km square. Also, a single total integrated sample, of about 30 hours duration, was collected at approximately 100 sites within an area 48 by 72 km (using 6 km spacings). Extensive tower profiles of meteorology at the release point were collected. RAWINSONDES, RABALS and PIBALS were collected at 3 to 5 sites. Horizontal, low-altitude winds were monitored using the INEL mesonet. SF/sub 6/ tracer plume releases were marked with co-located oil fog releases and bi-hourly sequential launches of tetroon pairs. Aerial LIDAR observations of the oil fog plume and airborne samples of SF/sub 6/ were collected. High-altitude aerial photographs of daytime plumes were also collected. Volume III contains descriptions of the nine intensive measurement days. General meteorological conditions are described, trajectories and their relationships to analyses of gaseous tracer data are discussed, and overviews of test day cases are presented. Calculations using the ARLFRD MESODIF model are included and related to the gaseous tracer data. Finally, a summary and a list of recommendations are presented. 11 references, 39 figures, 4 tables.
