摘要
为提高水下滑翔机搭载的温盐深剖面仪(CTD)数据处理质量及效率,在船载CTD数据处理方法基础上,研究了国产水下滑翔机CTD数据处理方法,基于Matlab GUI编程技术设计与研发了水下滑翔机CTD数据处理软件,利用该软件处理了“海燕”水下滑翔机GPCTD观测数据并与船用SBE 911 plus CTD、XCTD及MVP300传感器成果数据进行了对比,结果表明:GPCTD观测数据经处理得到的温、盐、声剖面整体趋势与各传感器成果数据基本一致,数据质量介于各传感器之间,其中温度、声速与XCTD、MVP数据更接近,而盐度与CTD数据更吻合,本文研究将为规范处理与使用水下滑翔机海洋水文数据提供参考。
In order to improve CTD data processing quality and efficiency of underwater glider,the CTD data processing method of domestic underwater glider is studied based on the data processing method of shipboard CTD,and the CTD data processing software of underwater glider is designed and developed based on MATLAB GUI programming technology.The GPCTD observation data of Petrel underwater glider is processed by using the software in case calculation,and compared with the observation data of SBE 911 plus CTD,XCTD and MVP300 sensors.The results show that the overall trend of temperature,salinity and sound velocity data of GPCTD is basically consistent with the results of all sensors,and the data quality is between all sensors,temperature and sound velocity are closer to XCTD and MVP data,while salinity is more consistent with CTD data.The software in this paper will provide a reference for processing and using oceanographic data of underwater glider.
