Stratopheric greenhouse gas observation using a balloon-borne cryogenic sampler at Syowa Station, Antarctica
Balloon-borne cryogenic samplers were launched from Japanese Antarctic Station, Syowa, on December 26, 2003 and January 5, 2004. Stratospheric air samples were successfully collected at 11 different altitudes from 10 to 30 km. After air samples were transported to Japan, they were analyzed for vario...
