Abstract. This article focuses on the determination and the validation of a new global mean sea surface (MSS) model which is named as SDUST2020 (Shandong University of Science and Technology 2020) with a grid of 1′×1′. This new model is established with 19-year moving average method and merges multi-satellite altimetry data over 27-year (from January 1993 to December 2019). The data of HY-2A, Jason-3 and Sentinel-3A are first ingested in the SDUST2020 MSS, but not in any other global MSS model, such as CLS15 and DTU18 MSS models. Validations, including the comparison with CLS15 and DTU18 MSS models, the comparison with GPS-leveled tide gauges and the comparison with altimeter data, are performed to estimate the quality of the SDUST2020 MSS model, and all the results show that the SDUST2020 MSS model is accurate and reliable. The SDUST2020 MSS dataset are freely available at the site (data DOI: https://doi.org/10.5281/zenodo.6555990, Yuan et al., 2022).

Short summary
Mean sea surface (MSS) is a relative steady-state sea level within a finite time span, which has the important applications in geodesy, oceanography and other disciplines. In this paper, SDUST2020, a new global MSS model is established with 19-year moving average method from multi-satellite altimetry data. Its global coverage is from 80° S to 84° N, grid size is 1'×1', and reference period is from January 1993 to December 2019.
