Tourists come here to Ragged Point, at the easternmost part of Barbados, for the view. I climb the 17-metre tower of the University of Miami’s Barbados Atmospheric Chemistry Observatory and collect samples of ash, dust and microorganisms, some of which have come all the way across the Atlantic Ocean. Reddish, iron-rich clouds from Africa reach us every year, usually between June and September, making Barbados hazy. When it’s clear, I enjoy the air and the landscape while making scientific observations — behind me in the photo is the northern coast.
