On April 7, 2003, the Sea-viewing Wide Field-of-View Sensor (SeaWiFS) captured this smoky image of Southeast Asia. Left of top center, skies are clearest over part of China, while the rest of scene, covering Myanmar, Thailand, Cambodia, Laos, Vietnam, and the South China Sea (at right), is blanketed with a layer of thick smoke from biomass burning (see related MODIS imagery) and possibly pollution.
