Flux Tower Measurements in Tasmanian Eucalyptus Forest 2013-2016

Featuring flux tower measurements of energy and mass exchange between the surface and atmosphere using eddy covariance techniques, processed with PyFluxPro (v3.4.15). It includes micrometeorology and meteorology data from 2013 to late 2016, though the dataset is incomplete for that period. The site is a tall, mixed-aged Eucalyptus obliqua forest in southern Tasmania with an elevation of 100 meters.

Use Cases

• Model Net Ecosystem Exchange (NEE) partitioning into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER) using gap-filled flux data.
• Analyze seasonal patterns of CO2 and H2O fluxes in relation to temperature, humidity, and rainfall measurements from the tower.
• Study soil moisture dynamics and soil heat fluxes in a fire-maintained eucalypt forest ecosystem.
• Investigate the impact of instrument changes, such as the switch from an open-path to a closed-path gas analyzer, on flux data continuity.

Strengths

• Data processed using the established PyFluxPro (v3.4.15) software as described by Isaac et al. (2017).
• Includes a comprehensive suite of measurements: gas fluxes (CO2, H2O), energy fluxes, and standard meteorology (temperature, humidity, wind, rainfall).
• Soil data (moisture, heat flux, temperature) are reported as complete for the measurement time period.
• Provides detailed site characterization including forest height (excess of 55m), soil type, and climate (mean annual precipitation of 1700 mm).

Limitations

• The micrometeorology and meteorology data from 2013 to late 2016 are incomplete due to ongoing problems after an instrument change in 2015.
• The dataset's temporal coverage is limited to a few years (2013-late 2016), restricting long-term trend analysis.
• Specific data volume metrics (row count, column count, file size) are unknown, making it difficult to assess computational requirements.
