The authors analyze a series of balloon borne measurements made on a yearly basis over Japan since 1985, of the stratospheric concentration of carbon dioxide. The data shows an altitude effect where the density decreased slightly until an altitude of 20 to 25 km, and then levels off. There is an observed increase of roughly 1.4 ppmv/yr observed in the CO{sub 2}density. From comparable measurements of air masses in the troposphere the authors argue the stratospheric CO{sub 2} is the result of vertical mixing of tropospheric air in the tropics, coupled with poleward transport.
