卫星高度计绝对定标中海面高梯度的计算
Calculation of Sea Surface Gradient in the Process of Satellite Altimeter Absolute Calibration
摘要
Abstract
The specific method of calculating sea surface gradient through mean sea surface model is given.Sea surface gradient of different coastal positions around the world is calculated through DTU13,CNES_CLS15 and WHU2013.The results calculated at 30 random compare points show that,the mean value of standard deviation of sea surface gradient in these points calculated by 3 models is less than 0.19cm/km.In the application of satellite altimeter calibration,the error of sea surface height difference computed through sea surface gradient should be less than 0.3cm.关键词
