介绍了一种新的海洋温度和温盐剖面自动质量控制系统。虽然检查是根据其他地方酌情使用的书面程序进行的，但一些质量控制算法仍需要大量开发。开发了一种新的自动船舶航迹检查：未检测到的位置误差的结果可能对海洋分析造成严重破坏。同样重要的是对照网格背景进行检查，这可以是气候学，但在地表附近，使用随时间推移而演变的估计是有利的。贝叶斯概率理论用于背景检查和与附近观测值相关的检查（伙伴检查）。该系统用于处理1956-2004年的档案数据。作为一个副产品，每月对这一时期进行无模型客观分析。该系统的各种版本用于近实时海洋分析，并用于初始化短期海洋预报和季节性大气-海洋预报。海洋观测系统的主要特点是沿着质量控制统计，可能发生的错误的例子和一些额外的问题的情况下。(c)2006 Elsevier B.

A new automated quality control system for oceanic temperature and temperature-salinity profiles is presented. Substantial development was needed for some of the quality control algorithms although the checks were based on documented procedures used elsewhere where appropriate. A new automated ship track check was developed: the results of an undetected position error can be very damaging to ocean analyses. Also important is a check against a gridded background, this can be a climatology but near the surface it is advantageous to use an estimate that is evolving over time. Bayesian probability theory is used in the background check and the associated check against nearby observations (buddy check). The system was used to process archive data for 1956-2004. As a by-product monthly model-free objective analyses for this period were produced. Versions of the system are used for near-real time ocean analysis and for initialising both short-range ocean forecasts and seasonal atmosphere-ocean forecasts. The main features of the oceanic observing systems are presented along with quality control statistics, examples of errors that can occur and some additional problematic cases. (c) 2006 Elsevier B.V.
