Yarramundi Irrigated Flux Tower Measurements of Carbon and Energy Exchange

Flux tower measurements quantify the exchange of energy, water vapor, and carbon dioxide between an irrigated paddock and the atmosphere using eddy covariance techniques. The Terrestrial Ecosystem Research Network processed the data using PyFluxPro and ONEFlux software to produce gap-filled Net Ecosystem Exchange partitioned into Gross Primary Productivity and Ecosystem Respiration. This release was published as part of the FLUXNET Shuttle project in April 2026.

Use Cases

• Modeling Net Ecosystem Exchange (NEE) dynamics from half-hourly flux tower measurements.
• Partitioning NEE into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER) components for carbon budget analysis.
• Correlating water vapor flux data with irrigation source quality metrics and canopy greenness photographs.
• Analyzing energy balance using concurrent measurements of temperature, humidity, rainfall, and net radiation.
• Studying the carbon sequestration potential of herbaceous perennial communities dominated by species like Digitaria sanguinalis and Bromus catharticus.

Strengths

• Data processed with established PyFluxPro and ONEFlux methodologies, ensuring standardized FLUXNET quality control.
• Includes gap-filled final product for key carbon flux variables (NEE, GPP, ER), enhancing usability for continuous time-series analysis.
• Site metadata provides detailed climate context (728 mm annual rainfall, specific temperature extremes) and soil characteristics.

Limitations

• Specific temporal coverage, row count, and data resolution (e.g., half-hourly, daily) are not provided in the description.
• Focus on a single, specific site near Richmond, NSW limits geographic generalizability.
• Vegetation community is dominated by exotic species, which may not represent native or other agricultural ecosystems.
