One of the many atmospheric measurement instruments onboard the NSF/NCAR Gulfstream V research aircraft during the HIPPO field project. The instruments measure atmospheric gases such as carbon dioxide and methane. HIPPO is a three-year field project that undertakes the most extensive airborne sampling of carbon dioxide and other greenhouse gases in the atmosphere to date, from the Arctic to the Antarctic. 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.
