Soil Moisture, Temperature, and Particle Size Data from Vallon de Nant Catchment

34 soil samples provide particle size distribution from 0.003 micrometers to 2 mm, classified by USDA soil class. Hourly soil moisture and temperature measurements are recorded at three stations (Auberge, Chalet, LaChaux) at multiple depths in the Vallon de Nant catchment. The dataset was contributed by Judith Eeckman of the University of Lausanne.

Use Cases

• Modeling soil water dynamics based on continuous moisture and temperature time series.
• Analyzing soil texture and classification based on particle size distribution results.
• Correlating soil physical properties with microclimate data from co-located weather stations.
• Studying spatial variability of soil characteristics within a small alpine catchment.

Strengths

• Includes two distinct, complementary data types: continuous time-series measurements and discrete granulometry results.
• Measurements are taken at three distinct spatial points and multiple depths, allowing for spatial analysis.
• Soil classes are provided according to the standardized USDA classification system.

Limitations

• Row count and total dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred from referenced PDF notices.
• Last update date is unknown; freshness unverified.
