Ti Tree East Flux Data: Energy and Mass Exchange in a Semi-Arid Australian Woodland

10-meter flux tower measurements from a mulga woodland in central Australia, processed to provide gap-filled data on ecosystem carbon, water, and energy exchange. The site, established in 2012 and managed by the University of Technology Sydney, monitors a mosaic of grassy mulga woodland and Corymbia/Triodia savanna on Pine Hill Station. Data processing used PyFluxPro (v3.5.0) to produce final Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER).

Use Cases

• Modeling carbon sequestration dynamics based on partitioned Net Ecosystem Exchange (NEE), Gross Primary Productivity (GPP), and Ecosystem Respiration (ER) data.
• Analyzing water and energy balance in a semi-arid biome using flux measurements of heat and water vapor.
• Studying the impact of long-term land management (cattle station with over three years without stocking) on ecosystem fluxes.
• Calibrating remote sensing products with ground-truth data from a site with detailed supplementary radiation and soil measurements.

Strengths

• Data is processed and gap-filled using the established PyFluxPro (v3.5.0) pipeline as described by Isaac et al. (2017).
• Includes a wide range of supplementary measurements: radiation, precipitation, soil temperature, soil moisture at multiple depths, and wind data.
• Site metadata is highly detailed, specifying canopy height (4.85 m), elevation (553 m), soil type (red sand), and long-term precipitation patterns (mean 305.9 mm).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling tasks.
• Freshness should be verified; the last metadata update was 2026-06-19, but the core data release is from 2023.
