Gatum Pasture Flux Tower Measurements from Southwestern Victoria

Southwestern Victoria flux tower data measures energy and mass exchange between a pasture surface and the atmosphere using eddy covariance techniques. The dataset, processed with PyFluxPro, provides gap-filled Net Ecosystem Exchange partitioned into Gross Primary Productivity and Ecosystem Respiration. The station was established on private farmland in February 2015.

Use Cases

• Model carbon dynamics by analyzing partitioned Net Ecosystem Exchange into Gross Primary Productivity and Ecosystem Respiration.
• Study seasonal pasture productivity using Gross Primary Productivity time series from the flux tower.
• Analyze the impact of sheep and cattle grazing on Ecosystem Respiration rates in a perennial grass pasture.
• Calibrate land surface models with gap-filled energy and mass exchange data from an Australian agricultural site.

Strengths

• Data processed using the established PyFluxPro (v3.4.15) software as described in a 2017 methodology paper.
• Provides a final, gap-filled product for key carbon flux variables like Net Ecosystem Exchange.
• Specific geographic context: located on a private farm in southwestern Victoria, approximately 300 km west of Melbourne.
• Clear ecosystem description: pasture composed of winter-active perennial grasses Phalaris aquatica and Trifolium subteraneum.

Limitations

• Unknown sample size, temporal resolution, and column count prevent assessment of dataset scale and feature richness.
• Data is from a single flux tower site, limiting geographic generalizability.
• Relies on gap-filling and partitioning models whose specific uncertainties are not detailed in the provided description.
