LARGE-SCALE DUST PLUMES AS SEEN FROM SATELLITE
 
Large-scale aerosol plumes can be identified in visible and near-infrared images obtained from sensors onboard earth-observing satellites. These plumes are of natural (e.g. desert dust storms) and/or anthropogenic origin and their transport over long distances can be monitored. Measurements such as these provide synoptic information on aeolian patterns, and in combination with phytoplankton chlorophyll maps, allow us to analyse the relationship between atmospheric dust input and phytoplankton productivity. It has been suggested that changes in phytoplankton production resulting from atmospheric input may potentially feedback to climate changes. Within this framework, satellite-derived maps of dust events and enhanced atmospheric aerosol distributions in the North Atlantic basin are examined.
