Figure 1 Fig. 1. Annual mean Southern Ocean CO2 flux from inversions using the control network (black), adding AMS (solid blue), and adding AMS and ASC (dotted blue) and from an ocean model forced with observed winds and fluxes (solid red) and constant wind and fluxes (dotted red). The shaded region shows the ±1 SD uncertainty on the fluxes for the control inversion. The long-term mean flux cannot be reliably estimated from the inversions (7), so the mean offset between the ocean model with variable forcing and inversion fluxes is not considered significant.
