Fires in southeast Australia continue their apparent march toward the coast on February 7, 2003. This pair of true- and false-color images from the <a HREF="http://modis.gsfc.nasa.gov" target="outlink">Moderate Resolution Imaging Spectroradiometer</a> (MODIS) on the <a HREF="http://terra.nasa.gov/" target="outlink">Terra</a> satellite show active fire fronts marked in red in both images. In the true-color scene (top), smoke fills the skies, while the image below uses false-color image analysis to minimize smoke and enhance the 2-million-plus-acre burn scar, which is deep red against bright green vegetation.The high-resolution image provided above is 500 meters per pixel. The MODIS Rapid Response System provides <a HREF="http://rapidfire.sci.gsfc.nasa.gov/gallery/?2003038-0207/" target="outlink">these images</a> at MODIS? maximum spatial resolution of 250 meters. Sensor: Terra/MODIS.
