HIPPO III Research Flight 11 :: Alaska to Colorado

HIPPO III :: RF11 Forward Cam

April 16, 2010

The pre-flight preparation notice had this to say about the day's flight from Alaska to Colorado:

"Power and access to the G-V at 0800, take off at 1000, estimated duration 6 hours. The flight will be at cruise altitude with one low approach at Watson Lake. The first half of the flight will be at or below the tropopause level (35-37,000 ft) and the second will be at cruise altitude (43,000 ft). Estimated flight duration 6 hours."

The flight went as planned, and the HIPPO Team arrived back in Colorado after completing yet another successful HIPPO campaign. The team was looking forward to settling back into their daily routine after spending close to a month hopping from time-zone to time-zone. Welcome back HIPPO Team!


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.
