NASA’s AIRS project… the transport of carbon dioxide around the world… the data have shown that, contrary to prior assumptions, carbon dioxide is not well mixed in the troposphere, but is rather “lumpy.”
AIRS data reveal a never-before-seen belt of carbon dioxide that circles the globe. More carbon dioxide is emitted in the heavily populated northern hemisphere than in the southern. As a result, the south is a recipient, or sink, for carbon dioxide from the north.
Several graphics and animations help bring ‘feel’ to the numbers.
