| 摘 要： | 通过全球Argo计划的实施，我们获得了大量的温盐剖面数据。如果对浮标所在洋区的状况不是很了解，很难判断Argo浮标电导率传感器的工作状态及盐度数据的可靠性。为了避免错误的数据，必须对Argo进行有效的质量控制。国家海洋信息中心根据西北太平洋海区的南森站和CTD温盐数据，建立了高质量的气候学温盐数据集，对投放在西北太平洋海区的Argo浮标数据进行了相应的质量控制。结果表明，利用Argo浮标所在海区的气候学数据对Argo数据进行质控是比较有效的方法之一。

| Abstract: | By the Argo program, a large number of T-S profiles can be observed in the world ocean. However, it is very difficult to examine changes of the sensitivity of the sensors equipped at the Argo floats, because it is difficult to understand their condition in the sea and the reliability of the data. We must quality control the Argo data to avoid the wrong conclusion deduced by the wrong data. One of the realistic methods for quality control of the Argo data is the comparison with the local climatology. NMDIS built a high quality climatological dataset in northwest Pacific based on the Nansen data and CTD data for the quality control. We checked the Argo data in this area and got good results. |
