海洋站自动观测数据在线质控系统开发与应用

Development and application of on-line quality control system for ocean station auto monitoring data

海洋站自动观测数据主要质控手段为延时月报质量审核,尚没有实时在线质控系统得到业务化应用。本文提出了一种海洋站自动观测数据在线质控系统,通过对水文气象等海洋观测要素进行逻辑分析,确定其极值区间和变化率区间阈值,将实时海洋观测数据与阈值进行比较,对错误或异常数据发出警示信息,提醒观测员进行处理,实现对海洋观测数据的在线质控。

The main quality control measure of automatic ocean observation data is delayed monthly quality check.However no on-line quality control system has been applied operationally.An on-line quality control system for automatic ocean observation data is proposed in this study.The threshold of extreme and rate of change is created by analyzing the characters of observation items.The alert will be triggered if the system detects errors or abnormal data to remind the operator for proper processing,therefore the on-line data quality control is accomplished.
