Flux Tower Measurements from Semi-Arid Eucalypt Woodland

This release contains flux tower measurements of energy and mass exchange between the surface and atmosphere in a semi-arid eucalypt woodland in Victoria, Australia. The data has been processed using PyFluxPro (v3.3.3) to produce gap-filled products including Net Ecosystem Exchange (NEE), Gross Primary Productivity (GPP), and Ecosystem Respiration (ER). The Otway station was operational from February 2007, measuring fluxes of heat, water vapor, and carbon dioxide via eddy covariance, along with supplementary environmental variables.

Use Cases

• Partition Net Ecosystem Exchange (NEE) into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER) to analyze carbon dynamics in a grazed woodland ecosystem.
• Analyze the relationship between photosynthetically active radiation (PAR) and carbon dioxide fluxes to model ecosystem productivity.
• Correlate soil temperature and heat flux measurements with seasonal variations in Ecosystem Respiration (ER).
• Model energy balance using concurrent measurements of net radiation, heat fluxes, and water vapor exchange.
• Investigate the impact of moderate seasonal rainfall (around 800mm annual average) on water vapor and carbon dioxide fluxes throughout the year.

Strengths

• Data is processed to a final, gap-filled product using the established PyFluxPro (v3.3.3) pipeline as documented in peer-reviewed literature.
• Includes a comprehensive suite of core eddy covariance fluxes (heat, water vapor, CO2) and supplementary measurements (temperature, humidity, rainfall, solar radiation, PAR, net radiation, soil temperature, soil heat flux).
• Site metadata is detailed, including location (Narrinda South, Victoria), land use (grazed dairy pasture), average grass height (0.1m), and climate specifics (mean daily temperature range 12-25°C, ~800mm annual rainfall).

Limitations

• The specific temporal coverage (start and end dates beyond the 2007 start) and total number of data records (rows) are not provided in the input.
• Data formats listed are HTML and PNG, which may not be standard, analysis-ready tabular formats (e.g., CSV, NetCDF), potentially requiring extraction or conversion.
• As the site is a single location on private, grazed land, findings may not be generalizable to other ecosystems or land management practices.

Provenance

Source

Terrestrial Ecosystem Research Network's Data Discovery, managed by CSIRO Marine and Atmospheric Research staff as part of the Cooperative Research Centre for Greenhouse Gas Technologies.

Collection Method

Measurements collected via eddy covariance techniques from a flux tower, processed using the PyFluxPro software (v3.3.3).

Time Range

The flux station was established in February 2007. The exact end date of data collection is not specified.

Freshness

The dataset metadata was last updated in March 2026, indicating ongoing curation, though the primary measurement period began in February 2007.

Geography

Narrinda South in south west Victoria, Australia; a semi-arid eucalypt woodland site used as grazed dairy pasture.
