Atmospheric O2 and CO2 concentrations, along with CO2 flux, have been observed in a megacity, Tokyo, Japan. The O2 : CO2 exchange ratio for net turbulent O2 and CO2 fluxes (ORF) between the urban area and the overlaying atmosphere was obtained, and we applied it to estimate the diurnal cycles of CO2 fluxes from gas and liquid fuel consumption separately. We found simultaneous observations of ORF and CO2 flux are useful in validating CO2 emission inventories from statistical data.
