【摘要】 通过均值过滤及Morison热滞后校正公式对存在温度误差的原始盐度进行修正。经过均值滤波后盐度尖峰现象消失,在温跃层由于热滞后导致的条状盐度抖动现象减小,上下行剖面盐度误差从0.013减小到0.004,总体修正盐度修正率提高3.05倍。结果表明利用该分段修正方法修正水下滑翔机搭载温盐深剖面仪(CTD)存在的盐度"尖峰"及热滞后误差效果显著。更多还原

【Abstract】 In this study, the formulae used to correct the mean filter and Morison thermal-lag errors were used to separately correct the salinity spikes and salinity thermal-lag errors in sea-wing glider payload conductance-temperature-depth(GPCTD). After correction, the thermal-lag shakes in thermocline are significantly reduced and the ratio of salinity correction is improved by 3.06 times. The results indicate that the sectional correction method is effective to correct the "peak" of salinity and thermal-lag error of GPCTD.更多还原
