Sea-viewing Wide Field-of-view Sensor (SeaWiFS) provided the land image layer and is a true colour composite of land vegetation for cloud-free conditions from September 18 to October 3, 1997. Each red dot over South America and Africa represents a fire detected by the Advanced Very High Resolution Radiometer. Buy this as a superb wall poster, a canvas print or a framed print.
