High Resolution Mean Sea Surface over China Sea Obtained with Compelling-Correction

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.
