Soil Temperature Profiles from a Coil-Shaped Fiber-Optic Sensor at Speulderbos

Measurements of soil temperature profiles were collected at the Speulderbos site (52.251048 N, 5.690061 E). The data was gathered using a coil-shaped fiber-optic distributed temperature sensor and reference sensors. Bart Schilperoort of Delft University of Technology created this dataset, which is described in a 2022 doctoral thesis.

Use Cases

• Modeling soil heat exchange and energy balance based on vertical temperature profiles.
• Validating fiber-optic distributed temperature sensing technology against traditional reference sensors.
• Analyzing temporal patterns in soil temperature for ecological or hydrological studies.
• Calibrating remote sensing or land surface models with in-situ temperature profile data.

Strengths

• Data includes measurements from a novel coil-shaped fiber-optic sensor, enabling detailed spatial profiling.
• Measurements are georeferenced to a specific research site (Speulderbos), providing precise location context.
• Dataset is linked to a formal doctoral thesis (Schilperoort, 2022), suggesting academic rigor and documentation.

Limitations

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