SDUST2020 MSS: a global 1′ × 1′ mean sea surface model determined from multi-satellite altimetry data

[摘要] This study focuses on the determination and validation ofa new global mean sea surface (MSS) model, named the ShandongUniversity of Science and Technology 2020 (SDUST2020), with a grid size of 1 ′ × 1 ′ . This new model was established with a 19-year movingaverage method and fused multi-satellite altimetry data over a 27-yearperiod (from January 1993 to December 2019). The data of HaiYang-2A,Jason-3, and Sentinel-3A were first ingested in the SDUST2020 MSS but not inany other global MSS model, such as the CLS15 and DTU18 MSS models.Validations, including comparisons with the CLS15 and DTU18 MSS models,GPS-leveled tide gauges, and altimeter data, were performed to evaluate thequality of the SDUST2020 MSS model, all of which showed that the SDUST2020MSS model is accurate and reliable. The SDUST2020 MSS dataset is freelyavailable at the site (data DOI: https://doi.org/10.5281/zenodo.6555990 ,Yuan et al., 2022).
