Carbon Monoxide Unwrapping Globe
Scientific Visualization Studio, NASA Goddard Space Flight Center,
Natural sources of carbon monoxide are emissions associated with vegetation and fires started by lightning. Human sources include industrial activity and burning of tropical forests. These are illustrated in this plot, where there is more carbon monoxide in the Northern Hemisphere, associated with more industrial activity, than in the Southern Hemisphere. High values are seen over industrial areas—North America, Europe, and Southeastern Asia.
