 The CO2 concentration of sample air is determined against working standard air using a NDIR. The CO2 concentration of the working standard air are determined against other two standard air using a mass spectrometer. The CO2 concentration of the "other two standard air" are determined against secondary standard air on TU-10 scale using a NDIR. The measurement method is detailed in Ishidoya et al. (2017 SOLA) and Ishidoya & Murayama (2014 Tellus B).

 This dataset must not be used together with the dataset observed by JMA owing to the problem described in "17. Description". Therefore, we specified the QC flag as "3: invalid" for all the data in this dataset.
 Operational/Reporting
 This CO2 dataset must be used only for the analysis of simultaneously-measured O2/N2, since the CO2 concentrations are systematically higher by about 1 ppm than those observed by JMA and posted on the WDCGG (see Ishidoya et al., ACPD).
