波浪骑士数据在高度计有效波高检验中的再处理

摘要

以2011年10～11月南海现场试验得到的9次波浪骑士测量数据,进行波浪骑士再处理与默认计算结果比对.比对结果表明两者平均误差为0.16m,均方根误差为0.32m,分析产生误差的原因在于波浪骑士默认计算有效波高时间段的中心与卫星过境时间不统一和未进行数据质量控制.研究表明在卫星高度计有效波高产品检验中,波浪骑士测量的有效波高需要进行再处理,以达到减少卫星高度计有效波高检验误差的目的.%In this paper,the measurement data of 9 in-situ experiments in the South China Sea are reprocessed,and the reprocessing result is compared with the default result.It shows that the mean error of two results is 0.16m,and the root mean square is 0.32m.The errors are caused by the inconformity of time period center of waverider default significant wave height (SWH) to the overflight time of satellite,and no quality control to data as well.So we can conclude that the waverider SWH data need to be reprocessed when using the SWH data to validate the altimeter SWH,which can decrease the error in the validation of altimeter SWH.
