Wombat State Forest Flux Tower Measurements 2010-2016

Aggregating flux tower measurements of energy and mass exchange between a forest surface and the atmosphere using eddy covariance techniques. It provides processed, gap-filled data including Net Ecosystem Exchange (NEE), Gross Primary Productivity (GPP), and Ecosystem Respiration (ER) for a secondary re-growth Eucalyptus forest site. The data were processed using PyFluxPro (v3.4.15) and include automated soil greenhouse gas flux measurements (CO2, CH4, N2O) from 2010 to 2016.

Use Cases

• Model carbon dynamics by analyzing the relationship between Net Ecosystem Exchange (NEE) and partitioned components Gross Primary Productivity (GPP) and Ecosystem Respiration (ER).
• Study seasonal ecosystem respiration patterns in a cool-temperate forest using gap-filled ER data across years.
• Analyze the impact of forest management practices, like selective harvesting, on long-term Gross Primary Productivity (GPP) trends.
• Correlate soil greenhouse gas fluxes (CO2, CH4, N2O) with atmospheric flux tower measurements to understand below-ground contributions.

Strengths

• Data is processed into a final, gap-filled product using the established PyFluxPro (v3.4.15) software.
• Includes coherent automated measurements of three key soil greenhouse gases (CO2, CH4, N2O).
• Provides detailed site metadata including dominant tree species, average canopy height (25 m), and long-term climate averages (mean annual temperature 12.1°C, annual rainfall 871 mm).
• Covers a multi-year time range for flux measurements from 2010 to 2016.

Limitations

• The specific number of data rows, columns, and file size are unknown, limiting assessment of dataset scale.
• Data collection ended in 2016, making it temporally stale for modeling current forest carbon fluxes.
• The dataset's focus on a single forest site (Wombat State Forest) limits geographical generalizability.

Collection Method

Flux tower measurements using eddy covariance techniques, processed with PyFluxPro (v3.4.15). Soil greenhouse gas fluxes measured with a trailer-mounted FTIR spectrometer.

Time Range

2010 to 2016 for soil greenhouse gas fluxes; flux tower measurement timeframe not fully specified but includes a sensor height change noted in January 2017.

Freshness

The metadata was last updated in March 2026, but the core measurement data covers 2010-2016.

Geography

Wombat State Forest, Australia. A secondary re-growth Eucalyptus forest site with specific soil (silty-clay over clay) and climate (cool-temperate to Mediterranean) details provided.
