 Details of measurement and calibration methods are reported by Matsueda et al. (1992, 1996) (See reference section). All of the measurements are re-calculated based on the MRI scale ("corrected" DF/NSC scale). The differences between the MRI and WMO scales are less than 3 ppb, as reported by Tsuboi et al. (2016, 2017) (See reference section).
