Eddy Covariance Flux Tower Measurements From Otway Pasture

This release contains flux tower measurements of energy and mass exchange between the surface and the atmospheric boundary-layer using eddy covariance techniques. Data were processed with PyFluxPro to produce gap-filled Net Ecosystem Exchange partitioned into Gross Primary Productivity and Ecosystem Respiration.

Use Cases

• Analyze Net Ecosystem Exchange (NEE) dynamics partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER) to model carbon sequestration.
• Correlate fluxes of heat, water vapor, and carbon dioxide with supplementary measurements like photosynthetically active radiation (PAR) and net radiation.
• Model the impact of environmental variables such as soil temperature and heat flux on ecosystem-level gas exchange.
• Study seasonal patterns in mean daily temperature, ranging from 25°C in February to 12°C in July, against measured carbon dioxide fluxes.

Strengths

• Data processed using the established PyFluxPro (v3.4.7) software as described by Isaac et al. (2017).
• Includes a final, gap-filled product for key carbon cycle metrics like Net Ecosystem Exchange.
• Station was managed by CSIRO Marine and Atmospheric Research staff as part of a Cooperative Research Centre.
• Supplementary measurements include temperature, humidity, rainfall, total solar, PAR, net radiation, soil temperature, and heat flux.

Limitations

• Specific row count, column count, and data size are unknown.
• Data is from a single location (Narrinda South, Victoria) on grazed dairy pasture, limiting geographic generalizability.
• File formats are listed as HTML and PNG, which may not be ideal for direct quantitative analysis without data extraction.
