Stratospheric Measurements of N2O, CFCl3 and CF2Cl2

Abstract Cryogenic and grab sampling methods were employed, alternately, on a ballon platform, to obtain stratospheric, whole air samples at altitudes of 15 and 20 km. The retrieved samples from two latitudes were analyzed for N2O, CFCl3 and CF2Cl2 content using a gas chromatograph.
