摘要:

本文应用风成海的相似理论,对测高中的海况偏差问题进行了物理分析。预计从测高测量中获得的无扰动的波陡和伪年龄将提供{物理相关且足够准确}的SSB估计。Jason-1,2,3和SARAL/AltiKa数据的分析表明,该方法在波的伪年龄和陡度空间上重建的SSB分布具有相似性和鲁棒性。这一结果被认为是一个基础,发展一个新的参数模型的SSB和分析的潜在物理效应。

英文摘要:

The theory of similarity for wind-driven seas is applied to the physical analysis of the problem of sea state bias (SSB) in altimetry measurements. Dimensionless wave steepness and pseudo-age derived from altimetry measurements are expected to provide {physically relevant and accurate enough} SSB estimates. Analysis of Jason-1,2,3 and SARAL/AltiKa data within the approach shows the similarity and robustness of SSB distributions re-casted onto space of wave pseudo-age and steepness. This result is considered as a ground for developing a new parametric model of SSB and for analysis of underlying physical effects.
