- Abstract:
This visualization shows global carbon monoxide concentrations at the 500 millibar altitude in the atmosphere from March 1, 2000 through December 31, 2000. Areas in red have 200 parts per billion of carbon monoxide or more at that altitude (around 5,500 meters), while areas in blue are 50 parts per billion or less. Carbon monoxide is an atmospheric pollutant and the highest concentrations come from grassland and forest fires in Africa and South America, although there is evidence that industrial sources may also be a factor. Atmospheric circulation rapidly moves the carbon monoxide to other parts of the world once it has reached this altitude. This data was measured by the MOPITT instrument on the Terra satellite.
