Dust Emissions Characterization and Mitigation

dustKeywords: dust, dust emission quantification, dust control

The dust emissions characterization and mitigation group of scientists in the Division of Atmospheric Sciences (DAS) (J.A. Gillies, V. Etyemezian, J.P. Engelbrecht, H. Moosmuller, others) specialize in understanding the physics of mineral dust emissions from natural and anthropogenic sources, its transport and deposition.  Our scientists are recognized as global leaders in this field of study winning awards for their research from the U.S. Department of Defense and Army Corp of Engineers, U.S. EPA, and U.S. Department of Energy.  In addition, our team is actively engaged in designing methods to control dust emissions as well as developing measurement methods to evaluate the effectiveness of these controls.  We can also evaluate the effectiveness of dust control methods developed by commercial ventures.

Within DAS we maintain a wide suite of instrumentation to measure dust emissions and dust emission potential from both natural and disturbed surfaces by wind erosion (Flux Towers, using U.S. EPA OTM 32; Portable In Situ Wind Erosion Lab [PI-SWERL]), and from paved, unpaved, and off-road surfaces by vehicles (TRAKER II and III, using U.S. EPA OTM 34).  We also maintain resources to characterize the particle size distribution and chemical and optical properties of dust, which are important for estimating the effects of dust on human health and radiative transfer in the atmosphere.
