基于Cryosat和Jason1GM数据的垂线偏差计算与分析

Calculation and Analysis of the Deflection of Vertical Derived from Cryosat and Jason1 GM Data

  • 摘要: 针对不同时空分辨率测高数据对测高垂线偏差计算结果的影响,联合使用Jason1波形数据和Cryo-sat数据,在对波形重跟踪处理和海面时变效应消弱预处理后,采用Sandwell方法和加权最小二乘法计算了三个典型区域的垂线偏差分量。研究结果与EGM2008模型检核表明,低轨道倾角的Jason1大地测量任务数据能有效提取垂线偏差东西分量信息,联合高轨道倾角的Cryosat测高数据可以提升垂线偏差计算精度,而引入重力场模型作为参考场可以进一步改进垂线偏差计算结果。

     

    Abstract: Satellite altimetry data with different spatial and temporal resolution has different effects oncalculation of the deflection of vertical,thus the Jason1waveform data and Cryosat data are combined.After the preprocessing of waveform retracking and the time-varying effect weakened,the deflection
