摘要分析了2011年10月1日至2014年12月6日期间海洋二号卫星高度计的有效波高资料。它们是根据原地浮标和其他同时运行的高度计进行校准和验证的:Jason-2、CryoSat-2和带有Argos和ALtiKa的卫星(SARAL)。总的来说,HY-2高度计测量值与浮标测量值吻合良好,偏差为-0.22米,均方根误差为0.30米。当减少主轴(RMA)回归程序应用于整个时期,RMSE减少了33%,为0.2米。然而,与其他卫星高度计的进一步比较揭示了HY-2在此期间估计的两个额外特征。第一,HY-2与其他用于公海(> 6米)的卫星高度计之间存在明显的不匹配。第二,从2013年4月开始,HY-2值出现跳跃式增加,这与HY-2传感器切换到备份状态以及随后的更新有关。
AbstractHai Yang-2 (HY-2) satellite altimeter measurements of significant wave height () are analyzed over the period from 1 October 2011 to 6 December 2014. They are calibrated and validated against in situ buoys and other concurrently operating altimeters: Jason-2, CryoSat-2, and Satellite with Argos and ALtiKa (SARAL). In general, the HY-2 altimeter measurements agree well with buoy measurements, with a bias of −0.22 m and a root-mean-square error (RMSE) of 0.30 m. When the reduced major axis (RMA) regression procedure was applied to the entire period, the RMSE was reduced by 33% to 0.2 m. A further comparison with other satellite altimeters, however, revealed two additional features of HY-2 estimates over this period. First, a noticeable mismatch is present between HY-2 and the other satellite altimeters for high seas ( > 6 m). Second, a jump increase in HY-2 values was detected starting in April 2013, which was associated with the switch to backup status of the HY-2 sensors and the subsequent update ...
