HIPPO III Research Flight 10 :: Northern Polar Regions

HIPPO III :: RF10 Forward Cam

April 15, 2010

RF10 from Anchorage towards the North Pole completed 5 dips, including missed approaches at Fairbanks Airport and in Deadhorse Airport. They had clear weather over most of the track, contrary to extensive cloudiness prediction (low cloud deck was present for about 300 miles North of Fairbanks). The HIPPO Team observed extensive network of fractures in the ice, with three 5 minute legs flown at 500', crossing a large number of the open leads. The G-V was able to ascend soon after turning around at 85°N and reached 45,000', taking a long stratospheric leg back to Anchorage.


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.
