| Research Abstract |
To elucidate vertical distributions and temporal variations of stratospheric greenhouse gases over Antarctic region, whole air samples of 10.7-7.0 LSTP were collected at 4 altitudes from 14 to 29 km above Syowa Station, Antarctica, by using balloon-borne compact cryogenic air samplers. The air samples were analyzed for concentrations of CO2, CH4, N2O and SF6 and ratios of O2/N2 and Ar/N2 in Japan and vertical distributions and secular trends of each component were obtained.
