The panel on the left is a 3.9 micron image over South America that may be used to locate several fire areas. These areas appear as bright spots in the animation. The right panel is a visible channel close-up over the central portion of the 3.9 micron channel image. Note the large amount of smoke over the region and the distinct smoke plumes originating near 5 degrees south. While the smoke is readily seen in the visible image, it is not easily seen at 3.9 microns because smoke is very poorly reflective at this wavelength.
