The Barbados Atmospheric Chemistry Observatory (BACO) has been operated by UM since 1971 to document the long-range transport of African dust to the Caribbean and the Americas. The site is used to answer questions regarding how African dust impacts clouds, climate, storms, ecosystems, and human health and how, in turn, African climate impacts dust transport. The site was founded by Emeritus Prof. Joe Prospero and continues under the direction of Prof. Cassie Gaston.
