Measurement of Pollution in the Troposphere, MOPITT, measures two important pollutants in the Earth atmospherecarbon monoxide (CO) and methane. This MOPITT image shows the relative amount of CO over North America from March 5-7, 2000. The animation shows the global distribution of carbon monoxide. Industrial activity produced the large amount of CO present in the Northern Hemisphere, and brush fires in Central Africa created the plume of CO stretching from Africa over the Atlantic Ocean.
