Short summary
A new diagnostic reveals how fluxes constrained by two different CO2 observing systems inform atmospheric CO2 simulations. The potential for GOSAT data to better resolve zonally asymmetric structures in the tropics year-round and in the northern extratropics in most seasons is shown. Using in situ data yields a better match to independent observations on the global, annual scale. Such complementarity of the observing systems can be exploited in greenhouse gas data assimilation systems.
