Windblown dust, emitted from the surface of the Earth to the atmosphere, has significant impacts on atmospheric phenomena, air quality, and human health. It alters radiation, cloud properties, precipitation, and atmospheric visibility, and contributes to long-range transport of organic chemicals, airborne bacterial species, and trace metals.
We develop physics-based models to better predict atmospheric dust emissions and transport across a wide range of scales. Our dust scheme is implemented in CMAQ modeling system of the US EPA and is publicly available.
