Otway Flux Tower Measurements of Energy and Carbon Exchange

Flux tower measurements from the Otway site in Victoria, Australia, processed using PyFluxPro and ONEFlux software. The dataset includes gap-filled Net Ecosystem Exchange partitioned into Gross Primary Productivity and Ecosystem Respiration. This release was produced as part of the FLUXNET Shuttle project and managed by CSIRO Marine and Atmospheric Research.

Use Cases

• Modeling Net Ecosystem Exchange (NEE) from supplementary measurements like temperature, humidity, and photosynthetically active radiation (PAR).
• Partitioning carbon flux into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER) using the ONEFlux processing method.
• Analyzing seasonal patterns in heat, water vapor, and carbon dioxide fluxes against mean daily temperature ranging from 12°C to 25°C.
• Correlating soil temperature and heat flux measurements with ecosystem respiration rates in a grazed pasture environment.

Strengths

• Data processed using standardized FLUXNET methodologies: PyFluxPro for quality control and ONEFlux for gap-filling and partitioning.
• Includes supplementary measurements for context: temperature, humidity, rainfall, solar radiation, PAR, net radiation, soil temperature, and heat flux.
• Site has long-term establishment, with measurements beginning in February 2007.

Limitations

• Specific row count, column count, and temporal coverage within the 2007 start date are not provided.
• Geographic scope is limited to a single flux tower site at Nirranda South, Victoria.
• Data represents a specific land use type (grazed dairy pasture), limiting generalizability to other ecosystems.
