Abstract EN
Observing System Simulation Experiments (OSSEs) have been conducted to evaluate the effect of Argo data assimilation on ocean reanalysis in the Pacific region.
The “truth” is obtained from a 5-year model integration from 2003 to 2007 based on the MIT general circulation model with the truly varying atmospheric forcing.
The “observations” are the projections of the truth onto the observational network including ocean station data, CTD, and various BTs and Argo, by adding white noise to simulate observational errors.
The data assimilation method employed is a sequential three-dimensional variational (3D-Var) scheme within a multigrid framework.
Results show the interannual variability of temperature, salinity, and current fields can be reconstructed fairly well.
The spread of temperature anomalies in the tropical Pacific region is also able to be reflected accurately when Argo data is assimilated, which may provide a reliable initial field for the forecast of temperature and currents for the subsurface in the tropical Pacific region.
The adjustment of salinity by using T-S relationship is vital in the tropical Pacific region.
However, the adjustment of salinity is almost meaningless in the northwest Pacific if Argo data is included during the reanalysis.
