A dataset consisting of numerically simulated oceanic velocities and sea surface height changes, provided conjointly from Eulerian and Lagrangian points of view, is made available as cloud-optimized archives on a cloud storage platform for unrestricted access. The Eulerian component of the dataset comprises oceanic velocity components at 0 m and 15 m depth, as well as total and steric sea surface height changes, obtained at hourly time steps for one year, with an approximate horizontal resolution of 1/25 degree on an irregular global geographical spatial grid, from the HYbrid Coordinate Ocean Model. The Lagrangian component of the dataset comprises the trajectories of particles advected in the Eulerian velocity field of the model. The particles were advected forward and backward for 30 days from a regular 1/4 degree grid in order to achieve 60-day long trajectories at 0 m and 15 m depths, with start times separated by 30 days, in 11 releases. This integrated dataset may help to link Eulerian and Lagrangian observational perspectives.
一个由数值模拟的海洋速度和海面高度变化组成的数据集，从欧拉和拉格朗日两个角度共同提供，以云优化存档的形式存放在云存储平台上，可供 unrestricted访问。该数据集的欧拉分量包括0米和15米深度处的海洋速度分量，以及总海面高度变化和热比容海平面高度变化，这些数据是通过 HYbrid Coordinate Ocean Model在一年中的每小时时间步长下获得的，在不规则的全球地理空间网格上，水平分辨率约为1/25度。该数据集的拉格朗日分量包括在模型的欧拉速度场中平流的粒子轨迹。粒子从规则的1/4度网格向前和向后平流30天，以便在0米和15米深度处获得60天的长轨迹，起始时间相隔30天，共进行11次释放。这个综合数据集可能有助于将欧拉和拉格朗日观测视角联系起来。
