中文摘要：

为了检验改进的Argo延时质量控制方法对盐度漂移误差的校正效果,分别利用现有质量控制方法和改进方法,对太平洋海域3个代表性Argo浮标盐度观测资料进行了延时质量控制,并利用船载温盐探仪资料或高质量浮标资料,对2种方法的质量控制结果进行了对比验证。结果表明,在温盐度变化较大的海域,改进方法不仅能够有效地检测和判断电导率传感器发生漂移的浮标起始观测剖面,而且可以有效地校正由电导率漂移所带来的盐度误差,且校正的精度高于质量控制方法。在温盐度分布比较均匀的海域,2种方法对浮标盐度漂移误差的校正结果几乎无差异。

英文摘要：

In order to check the effect of the improved Argo delayed-mode quality control method on correcting salinity drift errors,the existing Argo salinity delayed-mode quality control（Owens and Wong,OW）method and the improved method were used to correct the three representative Argo floats in Pacific Ocean,and the correction results verified by Conductivity Temperature Depth（CTD）data or high quality float data.The results show that in the sea area where the sea-water temperature and salinity change greatly（such as the Kuroshio-Oyashio intersection area,the Western Boundary Current region）,the improved method can not only effectively check and judge the start profile of the conductivity sensor drifting,but also effectively correct the salinity errors,and the correction accuracy is higher than OW method;that there are no significant differences in correction results of the two methods in the sea area where the distribution of temperature and salinity are homogeneous.
