| 摘 要： | 联合Geosat GM数据、ERS-1数据、T/P数据、T/P新轨道数据、ERS-2数据和GFO数据,采用强制改正法确定了中国近海(0°~41°N,105°~132°N)2′×2′格网分辨率的平均海面高模型,并将其与CLS01、GF-SC00.1和KMS04平均海面高模型进行了比较。统计结果显示,这些模型格网差值的RMS分别是10.17cm1、2.70 cm和16.13 cm,在剔除差值大于50 cm(分别剔除0.5%、0.89%和1.6%)的误差点后,RMS分别为7.98 cm1、0.29 cm和12.59 cm;与三年的Jason-1数据(Cycle 22~127)的平均框架相比,其RMS为7.40cm。

| Abstract: | Based on multi-satellite altimeter data(Geosat GM data,ERS-1 data,T/P data,new T/P data,ERS-2 data and GFO data),a MSS model over China sea and adjacent seas with 2′×2′resolution covers the areas of 0°-41°N,105°-132°N is obtained using compelling-correction.The MSS model is compared with CLS01,GFSC00.1and KMS04 models respectively,the corresponding RMS of the respective differences are 10.17 cm,12.70 cm and 16.13 cm,after eliminating error point where the difference is more than 50 cm(the proportions of the respective point eliminated are 0.5%,0.89% and 1.6%),the corresponding RMS of the respective differences are 7.89 cm,10.29 cm and 12.59 cm.Compared with the averaged-frame of three-year Jason-1(cycle 22 to 127),the corresponding RMS of difference is 7.40 cm. |
