Quality-controlled data on molar fraction of atmospheric CO2

All the time series have been updated due to a Flask and Calibration Laboratory minor internal scale update. The revision of CO2 data has been made to account for the response difference of isotopologue selective analyzers to the differences of d13C and d18O in CO2 of references gases compared to ambient air CO2 (see: Jordan A. (2024): Accounting for CO2 isotopic composition inhomogeneity in standard gases used for isotopologue specific CRDS measurements , https://community.wmo.int/events/22nd-wmoiaea-meeting-carbon-dioxide-other-greenhouse-gases-and-related-tracers-measurement)
