FINAL PUBLISHABLE REPORTGrant Agreement • March 26th, 2024
Contract Type FiledMarch 26th, 2024This project has provided traceable isotopic reference materials of CO2 and CH4, good practice guides for measurements of the isotope ratio of CO2, CH4 and in-field calibration strategies, advanced understanding of the carbonate reaction which currently provides traceability to the VPDB scale for δ13C and δ18O and improved the SI traceability of δ13C measurements. This improved infrastructure for traceable isotopic measurements of CO2 and CH4 in our atmosphere provides information to enable source apportionment of these most important greenhouse gases and thus allows governments to make informed policy decisions.
