High-Resolution Lysimeter Tracer Experiment Data from EPFL, March-August 2016

March-August 2016 data from a high-resolution vegetated lysimeter experiment conducted at EPFL in Lausanne, Switzerland. The dataset contains hourly hydrologic fluxes and tracer concentration measurements from a simultaneous injection of five solutes. Mitra Asadollahi from École Polytechnique Fédérale de Lausanne created this dataset.

Use Cases

• Calibrating soil water transport models based on hourly precipitation, irrigation, and drainage data.
• Analyzing solute transport and age dynamics based on tracer concentration time series.
• Comparing model performance for different solutes based on the five injected compounds (2,5-DFBA, 2-TFMBA, etc.).
• Studying the impact of vegetation on water fluxes based on the described vegetated lysimeter setup.

Strengths

• High-resolution temporal data with hourly flux measurements over a 6-month period.
• Multi-tracer experiment with five different solutes injected simultaneously.
• Includes complementary data on dry mass, soil volume, vegetation type, and injection volumes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
