Oil fires in Iraq
On Wednesday, April 2, 2003, the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite captured this clear image of the Middle East and surrounding countries. The most striking feature of the image is the large blackish-brown cloud of smoke blanketing Baghdad in the center of the image. Several thermal anomalies have been detected by MODIS—some in Baghdad and others in southern Iraq—and are marked with red dots. It is not unusual for MODIS to detect thermal signatures at oil wells or refineries. Underground, great pressure keeps various flammable gases mixed in with the liquid oil. When the oil is brought to the surface where air pressure isnt as great, those gases bubble up out of the oil are typically burned off, giving off a thermal signature and sometimes smoke. Other processes of oil production and refinement produce detectable thermal signatures. The hot spots detected right of image center may be from oil production and refinement. The plumes of smoke coming from the locations in southern Iraq, however, are larger than what MODIS typically sees.

Extent of Los Alamos fire seen by Landsat 7
The Cerro Grande Fire near Los Alamos, New Mexico, consumed about 47,650 acres and destroyed more than 200 buildings during the month of May 2000. This false-color Landsat 7 image shows much of the damage, even though some of the burn scar (red) is obscured by clouds. The extensive damage to the town of Los Alamos (beneath the bright green golf course in the center of the image) and Los Alamos National Laboratory (near the curving road at bottom center) is clearly shown. Note the surviving vegetation at the bottom of the steep ravines that run from left to right across the image. High winds caused the fire to jump the ravines without descending into them. Area residents may be vulnerable to mudslides during the rainy season that begins in July. Plants on the hillsides normally hold soil in place and slow water runoff, but after a fire water runs quickly downslope and can erode the bare slopes.
