Surface CUrrents from a Diagnostic model (SCUD): Pacific

The SCUD data product is an estimate of upper-ocean velocities computed from a diagnostic model (Surface CUrrents from a Diagnostic model). This model makes daily estimates of ocean currents by combining geostrophic and Ekman currents. The estimate is computed through derived coefficients such that the results best match ocean drifting buoys. The currents therefore are a best-estimate of currents at 15 meters (drifting buoys are drogued at 15 meters). The dataset is intended to diagnose trajectories of a tracer floating near the surface such as marine debris, oil spills, etc. The data are provided on a 1/4-degree grid for the Pacific.

PacIOOS is coordinated by the University of Hawaii School of Ocean and Earth Science and Technology (SOEST).

SCUD数据产品是基于诊断模型（表面诊断模型）计算得到的上层海洋速度估计值。该模型通过结合地转流和埃克曼流，每日对海洋流进行估算。该估计值通过导出系数计算，以使结果与海洋漂流浮标的数据最佳匹配。因此，这些流速是15米深度（漂流浮标被拖曳至15米深度）的最佳估计值。该数据集旨在诊断表面附近漂浮的示踪剂（如海洋垃圾、溢油等）的轨迹。数据以1/4度网格形式提供，覆盖太平洋区域。
