Tumbarumba Forest Carbon Flux Data with Bushfire Disturbance Record

Tumbarumba flux station in New South Wales provides eddy covariance measurements of energy, water vapor, and carbon dioxide exchanges between a wet sclerophyll forest and the atmosphere. The Terrestrial Ecosystem Research Network processed the data using PyFluxPro and ONEFlux software, producing gap-filled estimates of Net Ecosystem Exchange, Gross Primary Productivity, and Ecosystem Respiration. This release includes data capturing a significant bushfire disturbance event in December 2019.

Use Cases

• Modeling Net Ecosystem Exchange (NEE) dynamics from pre- to post-fire conditions using temperature, humidity, and radiation data.
• Partitioning carbon flux into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER) using the ONEFlux-processed, gap-filled product.
• Analyzing the impact of the 2019 bushfire on forest recovery by comparing canopy CO2 profiles and soil moisture measurements before and after the event.
• Studying energy balance and microclimate using supplementary measurements of wind speed, rainfall, and net radiation above the 70m canopy.
• Investigating soil-vegetation-atmosphere interactions through concurrent data on soil heat fluxes, soil temperature, and hyperspectral canopy properties.

Strengths

• Includes a documented, moderate-severity bushfire disturbance event from December 2019, enabling study of ecosystem response.
• Provides multi-level profiling with temperature, humidity, and CO2 measurements at seven levels within the 40m canopy.
• Data processed through established FLUXNET methodologies (PyFluxPro and ONEFlux) for quality control and gap-filling.

Limitations

• Contains a 10-month data gap immediately following the bushfire event, limiting continuous post-disturbance analysis.
• Geographic scope is limited to a single flux tower site in a specific wet sclerophyll forest type.
• Specific row count, temporal range, and data completeness metrics for the release are not provided.
