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

SDUST2020 MSS (Shandong University of Science and Technology 2020 mean sea surface) model with a grid of 1′×1′ is established with 19-year moving average method from multi-satellite altimetry data over 27-year (from January 1993 to December 2019). Its spatial coverage is 80°S-84°N. The missions data of Topex/Poseidon, Jason-1, Jason-2, Jason-3, ERS-1, ERS-2, GFO, Envisat, SARAL, HY-2A, Sentinel-3A and Cryosat-2 are ingested in the SDUST2020 MSS model.本数据集为山东科技大学（Shandong University of Science and Technology, SDUST）2020平均海平面（mean sea surface, MSS）模型，其网格分辨率为1′×1′。该模型基于1993年1月至2019年12月共计27年的多卫星测高数据，采用19年移动平均法构建而成，空间覆盖范围为南纬80°至北纬84°。本模型集成了Topex/Poseidon、Jason-1、Jason-2、Jason-3、ERS-1、ERS-2、GFO、Envisat、SARAL、HY-2A、Sentinel-3A及Cryosat-2的卫星测高任务数据。
