Britt Stephens :: Mapping Carbon Dioxide Across the Globe

Some of the bigest questions that we have about where our carbon dioxide is going focus on northern forests, tropical forests and different regions of the ocean. By taking this aircaft an flying from Boulder, Colorado to Anchorage to as far north out of Anchorage that we can get, all the way down the Pacific to New Zealand and as far south out of New Zealand as we can get, we're able to cover an enormous distance and we're able to see the influence of carbon dioxide from all of these different regions.


HIPPO is a landmark study for many reasons, not the least of which is it is the first time scientists have systematically mapped global distribution of carbon dioxide and other greenhouse gases in the atmosphere, covering the full troposphere in all seasons and multiple years.
