| 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). | |||||||||||||||||||||||||||
