Sea state bias in altimetry measurements within the theory of similarity for wind-driven seas

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. (C) 2019 COSPAR. Published by Elsevier Ltd. All rights reserved.

The theory of similarity for wind-driven seas is applied to analyze the sea state bias (SSB) in altimetry measurements, with dimensionless wave steepness and pseudo-age derived from altimetry data expected to provide accurate SSB estimates. The analysis of Jason-1,2,3 and SARAL/AltiKa data shows the similarity and robustness of SSB distributions re-casted onto wave pseudo-age and steepness space, serving as a basis for developing a new parametric model of SSB and analyzing underlying physical effects.
