Irrigated Pasture Flux Tower Measurements from Western Sydney

Aggregating flux tower measurements of energy and mass exchange between the surface and atmosphere using eddy covariance techniques. It originates from an irrigated, managed pasture site on the Western Sydney University campus, with data processed via PyFluxPro to produce gap-filled Net Ecosystem Exchange partitioned into Gross Primary Productivity and Ecosystem Respiration. The tower was 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.
• Study seasonal patterns in Ecosystem Respiration (ER) for an irrigated pasture site in a warm-temperate climate.
• Use eddy covariance flux data to validate or calibrate land surface models for improved pasture ecosystems.
• Investigate energy exchange dynamics at a site with sandy loam soil and flat topography.

Strengths

• Data is processed using the established PyFluxPro (v3.4.21) pipeline, which produces a final, gap-filled product.
• Site metadata includes specific climatic averages: 728 mm annual rainfall, 30.4°C mean max January temperature, and 3.6°C mean min July temperature.
• The dataset provides partitioned carbon flux components (GPP and ER) derived from Net Ecosystem Exchange.

Limitations

• The specific number of data rows, columns, and file size are unknown, limiting assessment of analytical scope.
• Sample data and column definitions are unavailable, complicating initial data exploration and schema understanding.
• Data files are in HTML and PNG formats, which are not standard for quantitative analysis and may require extraction.
