摘　　要：基于2017年4月至2018年8月西太平洋深海潜标观测数据,本文开展了锚系式声学多普勒流速剖面仪数据处理的质量控制研究工作。本文总结了质量控制的基本方法,重点解决了ADCP在流速观测中普遍存在的条带状异常问题。研究结果表明,质量控制常用的良好率与姿态(横摇、纵摇)并不能有效去除异常数据。本文进一步通过流速误差与相关幅值对数据进行质量控制,发现可以有效地去除条带状的异常数据,显著地提高了数据质量水平。因此,该工作对开展海流的结构特征、变异规律和动力机制等研究工作有重要的意义。Based on the observation platform of deep-sea subsurface mooring in the western Pacific Ocean between the period from April 2017 to August 2018, this paper carried out research on data quality control of the Acoustic Doppler Current Profiler(ADCP),summarized the basic method for the quality control of ADCP, and focused on solving the common problem of striped anomalies in ADCP velocity observations. The results show that the commonly used quality control methods, Percent Good, Roll, Pitch and Velocity, can’t effectively remove abnormal data. Through Velocity Error and Correlation Magnitude, the data quality was further been controlled, and the striped anomalies could be effectively removed, significantly improving the data quality level. Therefore, this work is of fundamental significance to the research on the structural characteristics, variation law and dynamic mechanism of ocean currents.
