To elucidate spatial and temporal variations of the tropospheric CO 2 concentrations over the Japanese islands, air samples were collected between 26 degrees N and 38 degrees N latitude during the period from June 1982 to February 1985 aboard commercial jet airliners. The amplitude of the seasonal variation of upper tropospheric CO 2 diminished gradually going southward with a phase delay of approximately half a month. Seasonally adjusted concentrations increased gradually in 1982, rapidly in 1983 and rather slightly in 1984 for all latitudes, and annual mean values were nearly the same for all latitudes in both 1983 and 1984. -from Authors
