Ocean Currents - Ocean Surface Current Analysis Real-time (OSCAR)

OSCAR (Ocean Surface Current Analysis Real-time) contains near-surface ocean current estimates, derived using quasi-linear and steady flow momentum equations. The horizontal velocity is directly estimated from sea surface height, surface vector wind and sea surface temperature. These data were collected from the various satellites and in situ instruments. The model formulation combines geostrophic, Ekman and Stommel shear dynamics, and a complementary term from the surface buoyancy gradient. Data are on a 1/3 degree grid with a 5 day resolution. OSCAR is generated by Earth Space Research (ESR) https://www.esr.org/research/oscar/oscar-surface-currents/

OSCAR（海洋表面流速分析实时系统）数据集包含了利用准线性稳定流动动量方程推导出的近海表面流速估计值。水平流速通过直接估计海面高度、表面矢量风速和海面温度得出。这些数据来源于不同卫星和现场仪器。模型构建融合了地转、埃克曼和斯托梅尔剪切动力学，以及由表面浮力梯度提供的补充项。数据以1/3度网格格式呈现，具有5天的时间分辨率。OSCAR由地球空间研究（ESR）生成，访问链接为https://www.esr.org/research/oscar/oscar-surface-currents/
