Irrigated Pasture Flux Tower Measurements from Yarramundi

Aggregating flux tower measurements of energy and mass exchange between the surface and atmosphere using eddy covariance techniques. It was processed with PyFluxPro (v3.4.18) to produce gap-filled products including Net Ecosystem Exchange (NEE), Gross Primary Productivity (GPP), and Ecosystem Respiration (ER). The data originates from an irrigated, managed pasture site on the Western Sydney University campus, with the tower established in October 2019.

Use Cases

• Analyze the relationship between Net Ecosystem Exchange (NEE) and Gross Primary Productivity (GPP) to model carbon dynamics in managed pastures.
• Partition Net Ecosystem Exchange (NEE) into its Gross Primary Productivity (GPP) and Ecosystem Respiration (ER) components to study ecosystem metabolism.
• Use gap-filled eddy covariance flux data to validate or calibrate land surface models for irrigated agricultural systems.
• Investigate seasonal patterns in Ecosystem Respiration (ER) within an intensively managed grazing operation on improved pasture.

Strengths

• Data is processed into a final, gap-filled product using the established PyFluxPro software (v3.4.18).
• Site metadata includes specific climate details: annual rainfall averages 728 mm, with a mean maximum January temperature of 30.4°C and a mean minimum July temperature of 3.6°C.
• The dataset provides detailed site characterization including soil texture (sandy loam), organic carbon content (<1%), and elevation (20 m asl).

Limitations

• The dataset's specific temporal coverage, row count, and column structure are unknown from the provided input.
• Data is from a single, specific site (Yarramundi Irrigated), limiting geographic generalizability.
• The original vegetation was cleared prior to 1950, representing a managed ecosystem rather than a natural state.
