Short summary
A joint inversion system is developed for estimating the carbon fluxes in 39 land and 11 ocean regions of the globe using both atmospheric CO2 and 13CO2 stable isotope data. In particular, a biospheric model is developed to model both CO2 and 13CO2 fluxes over land to constrain the inversion. Relative to CO2-only inversion, the joint inversion system improved the partition between land and ocean carbon fluxes and possibly the distribution of the fluxes among land regions as well.
