【摘要】:针对海洋浮标的波高观测数据,通过结合格拉布斯准则(Grubbs)、局地异常值检验方法和波高观测误差控制建立了一种实用的数据异常值质控方法并对波高观测异常值进行了质控效果检验。结果表明,该质控方法由于加入了波高观测误差控制,从而避免了将大量正常数据误判为异常数据,异常数据判断的准确率达到了较高水准。另外该方法也可以作为一种实用质控方法推广使用于其他海洋浮标观测要素。
[Abstract]:For wave height observations of ocean buoys, A practical method of data outliers quality control is established by combining Grubbsn criterion, local outliers test method and wave height observation error control method, and the quality control effect of the observed outliers of wave height is tested. The results show that the quality control method can avoid a large number of normal data being misjudged as abnormal data because of the addition of wave-height observation error control, and the accuracy of abnormal data judgment reaches a higher level. In addition, this method can also be used as a practical quality control method for other ocean buoy observation elements.
