基于Jason-1卫星测高数据提取海洋潮汐信息研究

Study on Ocean Tides Extracting Based on Jason-1 Satellite Altimetry Data

为深入研究中国近海区域海洋潮汐活动,基于Jason-1约6年的卫星测高GDR数据,采用调和分析法提取了中国近海区域交叉点的潮汐信息,得到主要分潮的振幅分布图。将其与验潮站资料和FES2004全球海潮模型相比较,其分潮振幅差异基本在3cm以内,结果符合性较好。

For the further study on ocean tides of China＇s offshore areas,it used harmonic analysis method to extract intersection tidal information of China offshore area,the amplitude distribution of main constituent has gotten.Compared it with the tide station data and FES2004 global ocean models,the partial tides amplitude difference are basically within 3cm,and the results are good conformity.
