Archivo: C14 and C13 variations since 1850

Descripción: Compiled historical data sets for Δ14CO2 (top) and δ13CO2 (bottom) from Graven et al. (2017). Annual mean values of Δ14C are provided for three zonal bands representing the Northern Hemisphere (30–90°N), the Tropics (30°S to 30°N), and the Southern Hemisphere (30–90°S). Annual mean, global mean values are provided for δ13C. The notation δ13C refers to the deviation of the ratio 13C/12C in a sample from a standard ratio 13C/12C. Similarly, Δ14C refers to deviations from a standard ratio termed “Modern.”
