Abstract

In this paper, a merged dataset of collinearly-processed sea surface height (SSH) derived from more than 200 repetition periods of Geophysical Data Record (GDR) data of T/P, Jason-1 and Jason-2 satellites is achieve. A direct-estimation method based on the merged dataset with a resolution of 0.25×0.25 is proposed. Compared with the previous non-parametric or parametric models, our direct-estimation method is with a better accuracy owing to the high spatial resolution of the merged dataset from various satellites. By applying the direct-estimation method in HY-2 satellite, we get the sea state bias (SSB) of HY-2 and demonstrate that this method is with a high accuracy, a good data extension and a wide applicability. Hence, the direct-estimation model can be effectively used for the SSB correction in the current and the subsequent in-orbit satellites.
