Modeling Erosion of Particulate Matter

By Ann Perry
August 5, 2011

A U.S. Department of Agriculture (USDA) scientist and his research partners have combined models of wind erosion and regional climate patterns to simulate the sources and dispersion of particulate matter-such as tiny bits of soil and other substances-blowing in dust storms around Mexico City.

People who inhale particulates with a diameter of 10 micrometers or less (PM10) can develop respiratory problems, so public health officials are anxious to predict how these airborne pollutants are dispersed over time.
