RF08 of HIPPO IV landed safely in Saipan. The GV was held at a constant 40,000 ft altitude by the Indonesian Air Traffic Control and only was able to start dips as about 4ºN, limiting profiling to only 3 dips on this flight. However, they were able to accomplish a high ascent before landing.





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.
