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)
