| ## Dataset Description |
|
|
| This dataset supports the comparative evaluation of time series embedding |
| methods for piezometric groundwater stations. It contains: |
|
|
| - **Station metadata** (4210 stations): coordinates, hydrogeological labels (milieu_eh), |
| department, altitude, and derived statistics |
| - **Univariate daily series** (2000 stations, ~10.6M rows): groundwater level (niveau_nappe_eau) |
| - **Multivariate daily series** (2000 stations, ~10.6M rows): groundwater level + |
| 3 ERA5 covariates (temperature_2m, total_precipitation, potential_evaporation) |
