Fig. 12

Yearly variations of the global land (a), ocean (b), and total (c) CO2 fluxes. (Fossil fuel emissions are excluded.) Light-gray and dark-gray solid lines represent the prior and true fluxes, respectively. The other colors indicate posterior fluxes from different iterations (10–300) of CTL. The blue dotted line denotes the 300th iteration result where model errors are nonexistent (NO_ERR)
