摘　　要：利用多源卫星测高数据构建9°~19°N、110°~116°E范围内分辨率为1′×1′的平均海面高模型,对ERM数据的共线平均、GM数据的时变改正、单星及多星间交叉点平差、格网化等方法进行阐述。实验结果表明,平均海面高模型与CLS15差值的平均值(mean)、均方根(RMS)、标准差(STD)分别为0.59 cm、 2.85 cm、2.79 cm,与DTU18差值的mean、RMS、STD分别为2.06 cm、4.17 cm、3.62 cm。利用独立于模型的测高数据(Sentinel-3B、HY-2B)验证模型的精度,建立MSS时使用HY-2A、Jason-3和Sentinel-3A卫星数据,再通过与T/P(TOPEX/Poseidon)数据的对比,分析新数据对MSS的提升作用。Using multi-source satellite altimetry data,we construct the mean sea surface height model with a resolution of 1′×1′in the range of 9°-19°N and 110°-116°E,and elaborate on the methods of collinear analysis of ERM data,removal of the temporal oceanic variability of geodetic mission(GM)data,adjustment of intersections between single and multiple satellites,and gridding.The experimental results show that the mean,RMS,and STD of the difference between the mean sea surface height model and CLS15 are 0.59 cm,2.85 cm,and 2.79 cm,respectively,and the mean,RMS,and STD of the difference with DTU18 are 2.06 cm,4.17 cm,and 3.62 cm,respectively.We use the model-independent altimetry data(Sentinel-3B,HY-2B)to verify the accuracy of the model,use HY-2A,Jason-3 and Sentinel-3A satellite data to establish the MSS,and then compare the new data with T/P(TOPEX/Poseidon)data to analyze the effect of the new data on the MSS.
