 NIES94 CH4 scale is higher than the WMO-CH4-X2004A scale by 4.1 ppb at around 1736 ppb and by 5.5 ppb at around 1942 ppb determined by the latest round robin intercomparison: https://www.esrl.noaa.gov/gmd/ccgg/wmorr/
 All of the CH4 data reported here can be used considering an overall uncertainty of less than 1ppb, although it is noted that an appropriate data selection is necessary for making time-series data sets of mean CH4, as reported by Matsueda et al.(2002a), and Matsueda et al. (2008).
