Ti Tree East Eddy Covariance Flux Measurements For Semi-Arid Woodland

27.5 tonnes per hectare of standing biomass characterize the Acacia aneura woodland monitored by this flux station. The Terrestrial Ecosystem Research Network processed flux tower measurements of energy, water vapor, and carbon exchange using PyFluxPro software. Data collection includes supplementary above- and below-canopy meteorological and soil measurements from a site approximately 170 km north of Alice Springs.

Use Cases

• Partition Net Ecosystem Exchange (NEE) into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER) using the PyFluxPro gap-filled product.
• Analyze the relationship between soil moisture measurements at depths up to 0.85m and ecosystem respiration or latent heat flux.
• Model carbon uptake dynamics using concurrent measurements of downwelling/upwelling shortwave radiation, temperature, and humidity.
• Investigate the impact of highly variable annual precipitation, ranging from 33mm to 712mm, on inter-annual Gross Primary Productivity.
• Assess energy balance partitioning using ground heat flux, net radiation, and sensible/latent heat flux measurements.

Strengths

• Provides gap-filled, final product data for key carbon fluxes (NEE, GPP, ER) using a standardized processing pipeline (PyFluxPro v3.4.17).
• Includes a multi-layered suite of supporting measurements: soil moisture at 4 depths, soil temperature, radiation components, and atmospheric profiles.
• Site metadata provides specific, quantitative ecological context including biomass (27.5 t/ha), canopy height (median 4.3m), and soil composition (91:8:1 sand:silt:clay).

Limitations

• The flux footprint is heterogeneous, with over 80% of measured fluxes sourced from a small mulga woodland east of the tower, limiting spatial representativeness.
• Precipitation data is from a Bureau of Meteorology station 45 km distant, not co-located, which may reduce accuracy for site-specific water balance analysis.
