Hydrogen and CO2 Soil Flux Measurements from a Scottish Grassland, 2024-2025

A grassland site at Easter Bush Farm in Midlothian, central Scotland, provides measurements of hydrogen and carbon dioxide gas fluxes from soil. The data were collected using aerodynamic gradient and eddy covariance techniques, alongside continuous soil temperature and moisture readings at multiple depths. The dataset is managed by the Environmental Information Data Centre and covers the period from August 2024 to September 2025.

Use Cases

• Compare aerodynamic gradient and eddy covariance flux measurement methods based on the co-located mast setup.
• Analyze the relationship between soil hydrogen flux and soil moisture/temperature based on the continuous sensor data at four depths.
• Model soil-atmosphere gas exchange in temperate grasslands based on the multi-gas (H2, CO2) flux measurements.
• Validate or calibrate soil flux models using the high-temporal-resolution environmental measurements.

Strengths

• Data collection employs two established flux measurement techniques (aerodynamic gradient and eddy covariance) for cross-validation.
• Continuous ancillary measurements include soil temperature and volumetric water content at four depths (5, 10, 20, 50 cm).
• Measurements were conducted at a long-term environmental monitoring site, suggesting consistent site management.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is embargoed until January 4, 2027, restricting immediate access.
