ResumoAbstract Stratospheric and tropospheric air samples were collected by means of a balloon-borne grab-sampler launched from Sanriku (39°N, 142°E) in the late summers of 1981, 1983, and 1984. The mixing ratios of CCl3F and CCl2F2 were determined precisely by using gas chromatography with ECD, and that of CH4, by gas chromatography with FID. The vertical profiles of these compounds are presented and compared with the model calculations.
