Otway Flux Data: Eddy Covariance Measurements from a Pasture in Victoria, Australia

Nirranda South in Victoria, Australia, is the location for this flux tower dataset measuring energy and mass exchange between the surface and atmosphere. The release contains processed, gap-filled data including Net Ecosystem Exchange partitioned into Gross Primary Productivity and Ecosystem Respiration, collected from a 10-meter tower from February 2007 onward. Data were processed using PyFluxPro (v3.4.15) and managed by CSIRO Marine and Atmospheric Research staff.

Use Cases

• Modeling Net Ecosystem Exchange (NEE) dynamics based on gap-filled carbon dioxide flux data.
• Partitioning carbon flux into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER) for ecosystem studies.
• Analyzing energy balance using supplementary measurements of temperature, humidity, and net radiation.
• Studying the impact of grazing on carbon and water vapor fluxes in a temperate pasture environment.

Strengths

• Data is processed and gap-filled using a documented method (PyFluxPro v3.4.15 as per Isaac et al., 2017).
• Includes supplementary measurements like soil temperature, heat flux, and multiple radiation types.
• Provides long-term temporal coverage starting in February 2007.
• Site characteristics are specified, including average grass height (0.1 m), annual rainfall (~800 mm), and temperature range (12-25 °C).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to a single site in south west Victoria.
