Evaluation of Atmospheric Transport and Dispersion Models in Highly Complex Terrain Using Perfluorocarbon Tracer Data
Project MOHAVE is a large monitoring, modeling, and data analysis study whose main goal is to assess the effects of the Mohave power plant (MPP), a large coal-fired facility in southern Nevada, upon visibility in the southwestern United States, in particular at Grand Canyon National Park (Pitchford and Green, 1997). Additional goals of Project MOHAVE include estimating the effects of other sources upon visibility in the southwestern United States, and evaluating atmospheric transport and dispersion models, and receptors models. One of the key design features of Project MOHAVE was the release of perfluorocarbon tracers (PFTs) at the Mohave power plant and other locations during a 30 day winter intensive study and a 50 day summer intensive study. Tracer and aerosol measurements were made at over 30 locations (mostly 24-hour average concentrations); upper air measurements were made with radar wind profilers, sodars, and rawinsondes; optical monitoring included transmissometers, nephelometers, and time-lapse photography.
