Dry River Savanna Carbon and Energy Flux Measurements

FLUXNET data from an Australian open forest savanna site contains gap-filled Net Ecosystem Exchange partitioned into Gross Primary Productivity and Ecosystem Respiration. Measurements began in September 2008 and are managed by The University of Western Australia and Charles Darwin University. This release was processed in 2026 using PyFluxPro and ONEFlux software.

Use Cases

• Modeling Net Ecosystem Exchange (NEE) dynamics using partitioned Gross Primary Productivity (GPP) and Ecosystem Respiration (ER) data.
• Analyzing relationships between carbon flux and ancillary measurements like soil moisture, leaf area index (LAI), and leaf-scale physiological properties.
• Correlating ecosystem respiration with seasonal soil heat flux and temperature measurements ranging from 14.6°C to 37.6°C.
• Studying energy balance using incoming/reflected shortwave radiation, net radiation, and heat flux measurements taken above a 12.3m canopy.
• Investigating water vapor flux in relation to local rainfall and mean annual precipitation of 895.3mm.

Strengths

• Data is gap-filled and processed using established FLUXNET methodologies (PyFluxPro, ONEFlux).
• Includes extensive ancillary measurements: LAI, leaf gas exchange, soil properties, and airborne remote sensing from 2008.
• Site provides long-term monitoring, established in September 2008 with precise location coordinates (-15.2588, 132.3706).

Limitations

• Specific row count, file size, and column details are unknown.
• Geographic scope is limited to a single flux tower site in Northern Territory, Australia.
• License terms for data use and redistribution are not specified.
