HIPPO IV :: Research Flight 03 :: Alaska to Hawaii

June 18, 2011

The flight plan had the HIPPO crew flying form Anchorage, Alaska, west to Cold Bay where they did a missed approach at a local airport. From Cold Bay, Alaska they flew south to Kona, Hawaii, along the way they did their "usual RF03" 7 dips ranging from about 1000' above the surface of the ocean to about 41,000'.

The earth's largest volcano - Mauna Loa - is located in Hawaii. NOAA has a station on top of the volcano where they measure atmospheric carbon dioxide (CO2). While measurements taken at that station are from a single fixed point, the measurements (and atmospheric sampling) taken from the GV as part of the HIPPO campaign come from a vertical profile of the atmosphere. The researchers took many samples near Hawaii and the volcano - from 1000' to 45,000' - and these can be compared to the CO2 measurements taken from the NOAA station on top of Mauna Loa

About HIPPO

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.
