Codes for the joint inversion system and the BEPS model, the prior CO2 fluxes, and the simulated spatial distributions of the various isofluxes over land and ocean University of Toronto http://faculty.geog.utoronto.ca/Chen/webdata/data/inversion

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.
