Resumo: | Two series of Observing System Simulation Experiments (OSSEs) are carried out with global data assimilation systems at 1/4° and 1/12° resolution using simulated altimetry (satellite) and in situ (Argo  oat) data derived from a 1/12° resolution free run simulation. The objectives are to quantify how well di erent data sets can constrain a global data assimilation system. The positive impact of multiple altimeter data is clearly evidenced on sea level and ocean currents. The addition of Argo has a major impact to improve temperature and demonstrates the essential role of Argo together with altimetry to constrain a global data assimilation system. Results derived from these OSSEs are consistent with those derived from experiments with real data (observing system evaluations/OSEs) but they allow a more detailed characterization of errors on analyses and forecasts.
