2004 UC Proceedings Abstract
From the Ground Up: Modeling Windblown Dust Track: Climate, Weather and Atmosphere Author(s): James Kuiper, Michael Lazaro, Young-Soo Chang, Larry Gorenflo, Veerabhadra Kotamarthi Windblown dust is a significant health and environmental quality problem in the Las Vegas area, often comprising a large fraction of PM10 air pollution. The region has been designated a PM10 nonattainment area by the U.S. Environmental Protection Agency (EPA). Understanding and quantifying the factors contributing to this problem and developing a model predicting the location and strength of the dust emissions are challenges requiring field measurements and extensive use of GIS technologies. Scientists at Argonne National Laboratory used empirical data from mobile wind tunnel measurements, topography, soil characteristics, and degree of surface sheltering to develop an urban-desert valley windblown dust model. The calculated emissions from this model were used in the EPA Community Multiscale Air Quality model to generate windblown dust distribution patterns for current and future conditions. Results supported an environmental impact statement for a Bureau of Land Management resource management plan for the region.
