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.
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 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 — 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). Browse with STAC Browser or load programmatically:
import pystac
catalog = pystac.Catalog.from_file(
"https://huggingface.co/datasets/NTU-CompHydroMet-Lab/mataian-moses-stac"
"/resolve/main/stac_catalog/catalog.json"
)
