The Willow and Nuttall Complex Fires in Arizona billowed out a plume of smoke containing particulate matter and carbon monoxide during the first weeks of July 2004. The plume drifted southward across the U.S.-Mexico border. This image shows carbon monoxide observation collected by the MOPITT sensor (Measurements Of Pollution In The Troposphere) on NASA’s Terra satellite between July 1 through 10, 2004. High values of carbon monoxide are visible in Mexico, to the left of the bottom center of the image. The location of the two fires can be identified by the high carbon monoxide levels in two locations in Arizona, to the north. High levels of carbon monoxide are shown in shades of green, yellow and orange. Low values (or clear skies) are blue.
