Alice Springs Mulga Flux Data: Energy and Mass Exchange Measurements

Terrestrial Ecosystem Research Network's Data Discovery provides flux tower measurements of energy and mass exchange from a semi-arid woodland site. Data were processed using PyFluxPro (v3.4.17) to produce gap-filled Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER). The station is located approximately 170 km north of Alice Springs, Australia, and has been operational since at least 2016.

Use Cases

• Modeling Net Ecosystem Exchange (NEE) dynamics based on gap-filled flux tower data.
• Partitioning ecosystem respiration and gross primary productivity in Acacia woodlands.
• Analyzing energy balance and water vapor fluxes using eddy covariance measurements.
• Studying the impact of variable precipitation (33mm to 712mm annually) on ecosystem carbon cycling.

Strengths

• Data is processed and gap-filled using the established PyFluxPro software (v3.4.17).
• Includes detailed site characterization: biomass of 32.5 t/ha, canopy height of 4.3m, and soil composition (74:11:15 sand:silt:clay).
• Comprehensive supplementary measurements include radiation, soil moisture, temperature, and precipitation at multiple heights and depths.

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.
• Freshness should be verified; last metadata update was 2026-06-19 08:13:59.636031.
