Calibration and testing or models of the global carbon cycle [electronic resource]
A ten-compartment model of the global biogeochemical cycle of carbon is presented. The two less-abundant isotopes of carbon, ¹³C and ¹⁴C, as well as total carbon, are considered. The cycling of carbon in the ocean is represented by two well-mixed compartments and in the world's terrestrial ecos...

| 520 | 3 | |a A ten-compartment model of the global biogeochemical cycle of carbon is presented. The two less-abundant isotopes of carbon, ¹³C and ¹⁴C, as well as total carbon, are considered. The cycling of carbon in the ocean is represented by two well-mixed compartments and in the world's terrestrial ecosystems by seven compartments, five which are dynamic and two with instantaneous transfer. An internally consistent procedure for calibrating this model against an assumed initial steady state is discussed. In particular, the constraint that the average ¹³C/¹²C ratio in the total flux from the terrestrial component of the model to the atmosphere be equal to that of the steady-state atmosphere is investigated. With this additional constraint, the model provides a more accurate representation of the influence of the terrestrial system on the ¹³C/¹²C ratio of the atmosphere and provides an improved basis for interpreting records, such as tree rings, reflecting historical changes in this ratio. | |
