全球海洋Argo网格资料集及其验证

Study on the global ocean Argo gridded dataset and its validationcommunity in coastal waters of Yantai

简要介绍了全球海洋Argo网格资料集的制作过程,并着重探讨了该数据集与历史观测资料集(如WOA09和TAO),以及同类型的Argo网格数据集等进行的比较与验证结果,发现利用逐步订正法构建的Argo网格资料与其他数据集相比,除了相互间吻合程度较高,能较客观地呈现出全球海洋中的一些大、中尺度海洋特征外,由Argo资料揭示的一些重要物理海洋特征的结构显得更细致,更能反映这些现象的演变过程和变化规律;加上Argo资料严格的质量控制过程,确保了重构的网格数据集的质量和可靠性。该资料集不仅可以作为研究全球海洋状况或揭示物理海洋现象的基础资料,还可为海洋数值模式的开边界和初始场提供参考依据。

The production of the global ocean Argo gridded dataset was briefly introduced in this paper. The comparison of the dataset with historical observation datasets （such as WOA09 and TAO）and other Argo gridded datasets suggested that it was not only in good agreements with others, but also could objectively present some ocean phenomena from middle to large scales. The structures or characteristics of some important physical oceanographic phenomena revealed by the Argo data were more detailed in the global ocean ,which could better reflect their evolution processes and variations. The strict quality control of Argo data ensured the reconstructed gridded dataset in good quality and reliability. The Argo gridded dataset not only could be used as the basic data in the study of global ocean conditions to reveal the physical oceanographic phenomena, but also provided references for open boundary and initial fields of ocean numerical model.
