| # MOSES Initiative — Matai'an Open Science and Engineering Sharing Platform |
|
|
| The **MOSES Initiative** (Mataian Open Science and Engineering Sharing Initiative) publishes scientific and engineering datasets for the **Matai'an Creek (馬太鞍溪)** watershed in eastern Taiwan (23.56°N–24.15°N, 121.16°E–121.68°E). All datasets are discoverable through a [STAC catalog](https://huggingface.co/datasets/NTU-CompHydroMet-Lab/mataian-moses-stac/resolve/main/stac_catalog/catalog.json). |

| ## Datasets |
|
|
| ### 1. Radar Rainfall — Typhoon Events (`stac_catalog/assets/radar-rain-monthly`) |
| |
| Machine-learning-predicted gridded rainfall for the Matai'an area, organized by typhoon event (2012–2026). |
| |
| - **Format**: Monthly NetCDF (`.nc`) and Zarr (`.zarr`) |
| - **Variables**: 1-hr accumulated rainfall, 10-min intensity, AOI mask, elevation |
| - **Spatial**: 48 × 42 grid points, ~1.2 km resolution |
| - **Temporal**: 10-minute intervals per month |
| - **Model**: XGBoost, trained on CWA radar data |
| - **License**: Proprietary (contact lab for access) |
| |
| See [`rain/zarr_tutorial.md`](https://huggingface.co/datasets/NTU-CompHydroMet-Lab/mataian-moses-stac/blob/main/stac_catalog/assets/radar-rain-monthly/zarr_tutorial.md) for a Python example using `xarray` + STAC to access Zarr data without downloading entire files. |
| |
| ### 2. Downstream Sediment (`stac_catalog/assets/sediment`) |
|
|
| Bed material particle-size distribution and physical properties sampled along Matai'an Creek. |
|
|
| - **Samples**: 22 sites (Dec 2025 – Jan 2026) |
| - **Methods**: Sieve analysis + hydrometer sedimentation test |
| - **Measurements**: Grain size distribution (Gravel → Clay), D10/D30/D50/D60, Cu, Cc, specific gravity |
| - **Reference**: [MOSES Report No. 001](https://huggingface.co/datasets/NTU-CompHydroMet-Lab/mataian-moses-stac/blob/main/stac_catalog/assets/sediment/MOSES_Initiative_001.pdf) — *Dataset of Bed Material Particle-Size Distribution and Physical Properties in Matai'an Creek* |

| ## STAC Catalog |
|
|
| All datasets are indexed in a [SpatioTemporal Asset Catalog (STAC)](https://stacspec.org/). Browse with [STAC Browser](https://radiantearth.github.io/stac-browser/#/external/huggingface.co/datasets/NTU-CompHydroMet-Lab/mataian-moses-stac/resolve/main/stac_catalog/catalog.json) or load programmatically: |
|
|
| ```python |
| import pystac |
| catalog = pystac.Catalog.from_file( |
| "https://huggingface.co/datasets/NTU-CompHydroMet-Lab/mataian-moses-stac" |
| "/resolve/main/stac_catalog/catalog.json" |
| ) |
| ``` |
