Soil and Meteorological Data with Simulation Framework for Alpine Shrub Heat Transfer

The Alnus-Nivus site near Col du Lautaret, French Alps, provides soil temperature and water content data at two depths and locations, alongside meteorological data from a nearby station. This dataset, created by Florent Dominé of CNRS, includes a finite element simulation framework for modeling heat transfer through green alder shrubs and snow. It is intended for testing thermal bridging effects in alpine environments, as referenced in a related 2023 publication.

Use Cases

• Simulating heat transfer through shrub branches and snow based on the provided finite element mesh and thermal conductivity parameters.
• Analyzing thermal bridging effects in alpine snowpacks using soil temperature data from near-shrub and open-grass locations.
• Validating snow and soil models by comparing simulated results with observed meteorological forcing derived from longwave radiation.
• Studying the impact of shrub presence on subnivean soil conditions using paired temperature and water content measurements.

Strengths

• Includes a ready-to-use finite element simulation framework with a defined shrub mesh.
• Provides paired soil measurements at two distinct microsites (under shrub and under grass) for comparison.
• Links to detailed meteorological data from a referenced station (FR-Clt) 750 meters away.
• Specifies typical material properties for simulations, such as wood and snow thermal conductivity.

Limitations

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