HIPPO IV :: Research Flight 04 :: Hawaii to Cook Islands

June 22, 2011

Due to some unforeseen circumstances, RF04, was delayed to Thursday June 22 and flew to Rarotonga, Cook Islands, rather then the planned flight to Pago Pago, American Samoa on June 21. 8 dips, 2 of which reached altitudes of 40,000', were performed along the way.

Each day prior to a flight, there is a full weather report and discussion surrounding the planned flight. Much of the HIPPO IV catalog is open to the public, so anyone can view the weather report for a give day - for example viewers can see the weather report for June 22, 2011.

Viewers can also see all of the images, and the combined images to make a movie from the forward looking camera on the GV, in the HIPPO IV Field Catalog.



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.
