Dust is an emerging core theme in Earth system studies. While dust as aerosol is known to have a significant climate forcing, the role of dust in the Earth system extends well beyond the impact on radiation, as it involves in a wide range of natural physical, chemical and bio-geochemical processes on a spectrum of scales. Dust contributes directly to the carbon cycle and transports iron that is critical to ocean biomass productivity and air-sea CO₂ exchange. A better representation of dust in global climate models is important for reduced uncertainties in climate projections. In this symposium, supported by the Sino-German Science Centre, we intend to examine the link between dust and climate change in the past, present and future from a multi-disciplinary perspective. We also hope to identify the research frontiers of dust research. Interested colleagues are warmly invited to attend. The symposium program (preliminary) and location is as attached.
