The "Collaborative Research: HIAPER Pole-to-Pole Observations (HIPPO) of Carbon Cycle and Greenhouse Gases Study" will measure cross sections of atmospheric concentrations approximately pole-to-pole, from the surface to the tropopause, five times during different seasons over a three year period. A comprehensive suite of atmospheric trace gases pertinent to understanding the Carbon Cycle will be measured. HIPPO missions transect the mid-Pacific ocean and return either over the Eastern Pacific, or over the Western Atlantic. The program will provide the first comprehensive, global survey of atmospheric trace gases, covering the full troposphere in all seasons and multiple years. This phase of the HIPPO project is the fifth and last one of five, taking place in September 2011. HIPPO Global Phase I took place in January 2009; Phase II in November 2009 and Phase III in April 2010. Phase IV is taking place in June 2011.
