AB: An inversion method has been developed for incorporating both atmospheric and oceanic constraints on surface fluxes of carbon dioxide. Previous estimates of the air-sea flux of carbon dioxide using only atmospheric constraints predict different ocean surface fluxes than do inversions of only ocean interior data, particularly in the temperate Pacific ocean. We simultaneously invert atmospheric $\mathrm{CO}_2$ concentrations and estimates of anthropogenic and preindustrial carbon concentrations from the ocean interior to produce a consistent estimate of surface fluxes. Sensitivity to transport uncertainty is studied using atmospheric transport estimates from TransCom3 and a suite of ocean GCM simulations.
