Atmospheric CO2 concentrations are expressed in parts per million by volume (ppmv) and reported
in the Scripps Institution of Oceanography X85 manometric mole fraction scale. Monthly values
represent in arithmetic means of the paired flask values for a given month as calculated by CDIAC.
Annual means are the arithmetic means of the monthly values and are calculated by CDIAC. Annual
means are provided only for years with complete monthly records.
