Quality-controlled data on molar fraction of atmospheric CO2

Instrument Id 329: H2O correction updated. An interpolation over time of the water vapor correction factors has been applied up to 2025-10-07. Instrument Id 395: H2O correction updated. An interpolation over time of the water vapor correction factors has been applied up to 2025-09-17. 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)
