HIPPO is a three-year field project doing the most extensive airborne sampling of carbon dioxide and other greenhouse gases in the atmosphere to date, from the Arctic to the Antarctic. (See http://www.ucar.edu/news/releases/200... .) Study results will help scientists understand in greater detail the behavior of carbon dioxide and greenhouse gases in the atmosphere and eventually lead to improved predictions about climate change. During the first mission, the NSF/NCAR Gulfstream V research aircraft will fly at altitudes ranging from 1,000 to 47,000 feet as it samples atmospheric greenhouse gases.
