Аннотация:This paper quantifies the value added by the
Greenhouse gases Observing SATellite (GOSAT) to
numerical models of the global carbon cycle for the
estimation of CO2 surface fluxes. The metric used here is
the theoretical uncertainty reduction, defined as one minus
the ratio of the posterior flux uncertainty to the prior ones.
Our results indicate that GOSAT should significantly
improve our knowledge of the CO2 surface fluxes over
terrestrial vegetated areas, even at the scale of a week and of
a few hundred kilometres. Over ocean and in spite of the
GOSAT sun-glint-pointing capability, large improvements
are seen only when the fluxes are aggregated both over
ocean basins and over a year.
