An important component of a joint Environmental Protection Agency---Department of Energy field experiment in Brush Creek Valley, Colorado in July--August 1982, was an aircraft sampling task to help verify the early morning ventilation of a gaseous tracer from the valley. The aircraft sampling supplemented a surface sampling network in the 650 m deep northwest-southeast oriented valley. A 100 m elevated tracer release 11 km up Brush Creek Valley from its confluence with Roan creek Valley was sampled using an airborne real-time tracer analyzer supplemented with periodic grab bag samples. Three experiments were conducted in the early morning hours (0400--1000 MST) of 31 July, 4 August, and 6 August.
