Gatum Pasture Eddy Covariance Flux Measurements 2015-2021

2015 to 2021 flux tower measurements from a grazed pasture site in Victoria, Australia, processed as part of the FLUXNET Shuttle project. The dataset contains gap-filled and partitioned estimates of Net Ecosystem Exchange, Gross Primary Productivity, and Ecosystem Respiration derived using ONEFlux software. It was produced by the Terrestrial Ecosystem Research Network using PyFluxPro for quality control.

Use Cases

• Model seasonal and interannual variability of Net Ecosystem Exchange (NEE) using partitioned Gross Primary Productivity (GPP) and Ecosystem Respiration (ER) data.
• Analyze relationships between carbon fluxes and supplementary meteorological variables like temperature, humidity, rainfall, and incoming shortwave radiation.
• Investigate soil-vegetation-atmosphere interactions by correlating soil moisture content and soil heat flux measurements with evapotranspiration and carbon dioxide fluxes.
• Validate and calibrate land surface models for pasture ecosystems using the gap-filled, quality-controlled flux product spanning six years.

Strengths

• Six years of continuous, gap-filled flux data from 2015 to 2021.
• Includes partitioned carbon fluxes (NEE, GPP, ER) alongside supplementary meteorological and soil measurements.
• Data processed using standardized FLUXNET methodologies (PyFluxPro, ONEFlux) ensuring comparability with a global network.

Limitations

• Data is from a single site, limiting geographic generalizability.
• The pasture ecosystem was intensively grazed, making results specific to managed agricultural systems.
• Site instrumentation was stopped in 2021, so data is not current beyond that year.
