This Sea-viewing Wide Field-of-view Sensor (SeaWiFS) image gives some idea of the broad reach of the smoke from the fires burning in southeastern Australia. The smoke (more yellow in color than the clouds it shares the skies with) on January 19, 2003, was being drawn eastward by the low pressure system visible to the south (left). Over subsequent days, the wind has shifted, first drawing the smoke towards the southwest, and then reversing course, once again pushing the smoke eastward.
