Abstract |
A set of three atmospheric tracer experiments was conducted in the Brush Creek Valley of western Colorado in the summer of 1982 as part of the U.S. Environmental Protection Agency Green River Ambient Model Assessment (GRAMA) program in conjunction with the U.S. Department of Energy's Atmospheric Studies in Complex Terrain (ASCOT) research program. Experiments were designed to determine how nighttime tracer concentrations on the valley floor and sidewalls arising from an elevated point source would change following sunrise during the temperature inversion break-up period. Many physical processes were observed in the tracer and meteorological experiments, including nocturnal down-valley plume transport and diffusion, post-sunrise CBL growth, fumigation of the elevated plume, upslope flow development within the CBL, subsidence over the valley center, and high post-sunrise concentration on the sidewall. |
