CAMELS-ES: Hydrometeorological Catchment Data for Spain

1991 to 2020 data covers 269 catchments across Spain. This dataset provides catchment attributes, meteorological time series, and discharge records, contributing to the global Caravan initiative for hydrological modeling. It integrates static catchment data from HydroATLAS and ERA5-Land with dynamic simulations from the European Flood Awareness System (EFASv5).

Use Cases

• Benchmarking hydrological model performance across diverse Spanish catchments based on catchment attributes and discharge records.
• Analyzing long-term meteorological trends (1991-2020) using ERA5-Land time series data.
• Evaluating European Flood Awareness System (EFASv5) discharge simulations against observed records.
• Studying the relationship between static catchment characteristics from HydroATLAS and hydrological response.

Strengths

• Covers a large sample of 269 catchments, supporting statistically robust analysis.
• Provides a long, consistent 30-year time series from 1991 to 2020.
• Integrates multiple authoritative data sources, including ERA5-Land reanalysis and official Spanish discharge records.

Limitations

• Specific column names and dataset size (rows, file size) are not provided in the source metadata.
• The last update date is unknown, limiting assessment of data currency.
• Relies on model-derived data (ERA5-Land, EFASv5) which may contain uncertainties compared to direct observations.
