General Comment: GAW Rep. No. 242, B=Network compatibility goal. Uncertainties are provided as 2 sigma. They represent the sum of random and systematic error. 14CO is provided in molec / cm3. Unlike CO2, the CO mixing ratio is highly variable depending on where you are. Unlike e.g. 13CO2, the amount of 14CO is not proportional to the most common isotopologue 12CO.  For this reason per mil is not used in the literature. Confidence: firm
Def: :Result of impact studies of actual data used in actual applications of numerical or conceptual models
