Longreach Grassland Flux Tower Measurements for Carbon Exchange

Flux tower measurements of energy and mass exchange between the surface and atmosphere using eddy covariance techniques. Data were processed with PyFluxPro (v3.5.0) to produce gap-filled Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER). The station is located in arid tussock grassland at Rosebank Station, Queensland.

Use Cases

• Analyze the partitioning of Net Ecosystem Exchange (NEE) into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER) to study grassland carbon dynamics.
• Model energy and mass exchange fluxes using eddy covariance data to understand surface-atmosphere interactions in arid ecosystems.
• Investigate the impact of sheep and beef cattle grazing on carbon fluxes (NEE, GPP, ER) in Mitchell grass rangelands.
• Use gap-filled flux data processed by PyFluxPro for validating remote sensing estimates of ecosystem productivity.

Strengths

• Data processed using the standardized PyFluxPro (v3.5.0) pipeline as described by Isaac et al. (2017), ensuring methodological consistency.
• Provides a final, gap-filled product for key carbon flux variables (NEE, GPP, ER), enhancing usability for time-series analysis.
• Site is ecologically characterized as arid tussock grassland with specific grass species (Astrebla lappacea, Astrebla squarrosa) and soil type (black vertosol).
• Dataset is part of a 2024 release, indicating recent data collection and processing.

Limitations

• The specific number of data rows, columns, and file size are unknown, limiting assessment of dataset scale and granularity.
• Data is presented in HTML and PNG formats, which may be less convenient for quantitative analysis compared to structured tabular formats (e.g., CSV).
• Geographic coverage is limited to a single flux tower site in Queensland, Australia, restricting broader spatial analysis.
