43.2 km² of a high-alpine catchment in the Swiss Alps was simulated for the 2014-2015 water year using the Alpine3D model. The dataset, from ENVIDAT, combines multi-scale field data including snow lysimeter measurements, distributed snow depths, and streamflow to validate model performance. It was published in 2017.
Use Cases
- Validate snowpack runoff simulation accuracy using site-scale R² values (0.95 vs. 0.61) from lysimeter data.
- Analyze the impact of heterogeneous snow distribution on sub-basin runoff pulse timing and melt period duration.
- Compare catchment hydrological response using Nash coefficient metrics (0.85 vs. 0.74) from different snow distribution representations.
- Study liquid water transport scheme performance across site, sub-basin, and basin scales using modeled snowpack data.
Strengths
- Model validation uses multi-scale field data: snow lysimeters, distributed snow depths, and streamflow.
- Simulation covers a specific 43.2 km² catchment for a full water year (2014-2015).
- Quantitative performance metrics are provided, including R² and Nash coefficients for model comparisons.
Limitations
- Dataset scope is limited to a single catchment and one water year, reducing generalizability.
- The calibration process is noted to smooth out differences in model performance metrics.
- Specific row counts, column details, and raw data volumes are not provided.
