| ## Dataset Description | |
| CMEMS is an HDF5 gridded dataset for global ocean forecasting tasks. By integrating satellite and in situ observations with numerical ocean models, it provides real-time analyses, forecasts, and historical reconstructions for a variety of variables. | |
| ## Supported Tasks | |
| This standardized data repository contains 7 annual files covering 1993-1999. Each file provides ocean variable fields, global means, and global standard deviations, and can be used for XiHe model training, validation, testing, inference input, and evaluation. | |
| ## Dataset Format and Structure | |
| Each annual file is in HDF5 format and follows the path pattern `data/<year>.h5`. Each file contains: | |
| | HDF5 Path | shape | dtype | Description | | |
| |---|---|---|---| | |
| | `fields` | `[3, 96, 2041, 4320]` | `float32` | 3 time samples, 96 variables, and a global grid | | |
| | `global_means` | `[1, 96, 1, 1]` | `float32` | Global means aligned with the variable order | | |
| | `global_stds` | `[1, 96, 1, 1]` | `float32` | Global standard deviations aligned with the variable order | | |
| `fields.attrs["variables"]` contains the names of 96 variables, and `fields.attrs["time_step"]` is 24. The detailed schema is provided in `metadata/schema.yaml`. | |
| ## How to Use the Dataset | |
| This dataset is compatible with the `OneScience-Sugon/XiHe` model. | |
| Download the dataset: | |
| ```bash | |
| hf download --dataset OneScience-Sugon/CMEMS --local-dir ./CMEMS | |
| ``` | |
