GEST Ocean Surface Current 2.0

The GEST Ocean Surface Current product 2.0 builds upon the GEST Ocean Surface Current product 1.0 (doi: 10.5281/zenodo.8329991), which estimates ocean surface currents at a 15 m depth using GESTNet, integrating multi-scale physical processes including Geostrophic and Ekman currents, wave-induced Stokes drift, and Tidal currents. This global daily product spans the period from 2006 to 2019, featuring a spatial resolution of 0.25°. It is anticipated to be a reliable indicator of actual ocean circulation.GEST海洋表层流产品2.0（GEST Ocean Surface Current product 2.0）以GEST海洋表层流产品1.0（DOI: 10.5281/zenodo.8329991）为研发基础。该1.0版本产品依托GESTNet模型，对15米深度处的海洋表层流进行估算，整合了地转流、埃克曼流、波浪诱导斯托克斯漂流以及潮汐流等多尺度物理过程。本次发布的2.0版本为全球逐日产品，时间覆盖2006年至2019年，空间分辨率达0.25°，有望成为实际海洋环流的可靠表征指标。
