The data fusion of the significant wave height measured with “HY-2” satellite altimeter

摘要: 利用反距离加权法根据不同的方案融合得到2011年10月1日至2012年3月8日“HY-2”和“Jason-1/2”, “ENVISAT”卫星高度计的10 d平均波高, 借助NDBC提供的浮标数据对融合结果进行验证和比较, 结果表明:不同的融合结果均可以很好地反应海洋表面的真实情况;“HY-2”卫星高度计数据在多源卫星高度计数据融合中可以与其他卫星高度计数据一样发挥作用, 甚至可以替代已经停止运行的“ENVISAT”参与多源卫星高度计数据融合。Abstract: The data of significant wave height (SWH) obtained with “HY-2” and other satellite altimeters from October 1, 2011 to March 8, 2012 are merged by using the inverse distance to a power method in the different combination. The data fusion results are compared with the NDBC buoy data. The comparisons indicate that:(1) all the data fusion in different combinations could reflect the real situation of sea surface; (2)the data of the SWH measured with “HY-2” altimetry can work well in the multisatellite altimeters data fusion and even can take the place of EVNISAT for its sudden lost.
