The Aerosol-Weather-Climate Group at Michigan Technological University has broad interests in the interactions between atmospheric aerosols and the Earth system. Currently, we are mainly interested in dust aerosol, the most abundant aerosol species from terrestrial sources. Using remote sensing, physical models and AI/ML techniques, we study the physical processes and anthropogenic activities modulating the dust source properties, dust aerosol life cycle, and the associated impacts on weather, climate, and air quality.
