【摘要】 利用改进的Barnes逐步订正法,结合一个混合层模型,构建完成了一个新版(2004-2017年)全球海洋(79.5°S~79.5°N,180°W~180°E)Argo三维网格温、盐度资料集及衍生数据产品。与旧版网格数据集相比,新版数据集采用一阶近似(表层温、盐度通过混合层内温、盐度线性拟合得出)的混合层模型,改善了资料集在表层的准确性;与WOA13资料集、同类Argo资料集和锚碇浮标观测资料的可靠性检验结果表明,新版全球海洋Argo网格数据集提供的资料是可信的,其质量也是有充分保证的。更多还原

【Abstract】 Based on an improved Barnes successive correction method, combined with a mixed layer model, a new version of the global ocean(79.5°S～79.5°N,180°W～180°E) Argo 3D gridded temperature/salinity dataset(2004-2017) with its derived products are developed.In contrast to the old version of the dataset,the mixed layer model of first-order approximation is adopted,and improves the accuracy of the dataset at the surface. The new version of the global Argo gridded dataset is verified to be creditable through a reliability checkby means of WOA13,the other Argo datasets and moored buoy observations.更多还原
