Abstract
Data fusion methods such as inverse distance to a power method, Kriging method and successive correction method are studied in this paper. The appropriate model and parameters for these methods are achieved for the fusion of ocean wave significant wave height (SWH) data from GFO, Jason-1 and Envisat altimeters in China seas and nearby. The factors which influence the fusion results are also analyzed. It is shown that (1) the characteristics and distribution of merged SWH data are consistent with the statistical data in the study area; (2) there is little difference between the merged results for different fusion methods in case the altimeter data are not sparse; (3) the window size of the filters is about 2.5°×2.5°-3°×3° to reach reasonable results; (4) data from at least 3 satellites are needed in the fusion processes.
