Abstract

Abstract

To get sea surface temperature by remote sensing has high real-timeliness,but the data quality varies with the at mospheric environment.To solve sea surface temperature by the assimilation technology has high local precision,but the coverage and real timeliness are poor.As the two technologies suit to different situations,it is proposed to apply the data fusing technology so that the two technologies can complement each other with their respective advantages,i.e.,can carry out consistence evaluation and weighted fusing calculation of the data points according to their respective advantages and limitations.While the precision is improved,the result's uncertainty is quantified and evaluated.The results of the sampling test taking the China's eastern sea area as an example show that the fusing method fits the complex environment better.
