Tracer distributions in Brush Creek Valley drainage flow derived from 1984 ASCOT data. Technical memo
Technical Report
·
OSTI ID:5913565
Observed concentrations of two perfluorocarbon tracers, which were released simultaneously at the same site at two different heights within drainage flow in Brush Creek Valley during the 1984 ASCOT experiment, were analyzed. Along-valley-axis and across-valley average tracer concentration isopleths from elevated and surface releases were plotted every 1.5 hrs from 0100 to 1000 MST for two experimental dates, 26 September and 30 September. These tracer distributions are presented in the report, and are discussed in relation to the release height, topography, and meteorological conditions. The results and analysis given here are intended to aid in understanding pollutant transport and dispersion in deep valleys, and in evaluating model simulations.
