Abstract
Extensive validation of altimetry measurements is of fundamental importance prior to their scientific or commercial applications. In the present study, new CryoSat-2, HY-2A, SARAL/AltiKa, Jason-2 measured Sea Surface Height (SSH) obtained from RADS (Radar Altimeter Database System) and DUACS (Data Unification and Altimeter Combination System) are cross-validated and compared with tide gauge data in China Seas. The CryoSat-2 SAR (Synthetic Aperture Radar) and LRM (Low Repetition Mode) modes are available in the Bohai Sea/Yellow Sea and East China Sea, respectively, which enables the initial evaluation of the performance of the new satellite altimetry over the regions. The results demonstrate high consistency between the new altimetry missions with a root mean square difference of 3–5 cm in SSH. Coherent SSH time series are observed from the new satellite altimetry measurements and tide gauge data. The findings are important for continuous mapping the sea level variations based on 23 years of altimetry measurements in China Seas.
