HIPPO: HIAPER Pole-to-Pole, 2008 - 2011

This is a collection of photos from the HIAPER Pole-to-Pole Observations (HIPPO) project which investigated the Carbon Cycle and greenhouse gases throughout various altitudes of the western hemisphere through the annual cycle. HIPPO was supported by the National Science Foundation (NSF) and its operations were managed by the Earth Observing Laboratory (EOL) of the National Center for Atmospheric Research (NCAR). Its base of operations was EOL's Research Aviation Facility (RAF) at the Rocky Mountain Metropolitan Airport (RMMA) in Jefferson County, Colorado. The main goal of this program was to determine the global distribution of carbon dioxide and other trace atmospheric gases by sampling at various altitudes and latitudes in the Pacific Basin.
