Regularly, huge amounts of mineral dust are transported over long distances impacting air quality, health, weather and climate thousands of kilometers downwind of the source. This session will discuss the long-range transport of mineral dust across the Atlantic Ocean into the Caribbean, South America, Central America, and the USA. Interpretation of observations e.g. from large field experiments such as SALTRACE, Dust-ATtACk, PRADACS and SOPRAN and modeling studies are encouraged. Special attention will be given to the understanding of the transformation of mineral dust during long-range transport and its impact on climate (cloud formation, precipitation, hurricane suppression, interaction with the ocean).
