Flux Tower Measurements from Daintree Rainforest 2008-2024

Encompassing flux tower measurements of energy and mass exchange between the surface and atmosphere using eddy covariance techniques, processed with PyFluxPro (v3.4.17). It originates from the Cow Bay flux station in the Daintree Rainforest, established in December 2008 and managed by James Cook University. The data includes gap-filled Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER).

Use Cases

• Partition Net Ecosystem Exchange (NEE) into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER) to model carbon dynamics in a mesophyll vine forest.
• Analyze the relationship between incoming/reflected shortwave radiation, net radiation, and fluxes of heat, water vapor, and carbon dioxide.
• Investigate the impact of site-specific conditions, such as 3935 mm mean annual precipitation and 90 m elevation, on measured ecosystem respiration (ER).
• Study artifacts in downwelling radiation data caused by shadowing of radiometric equipment relative to solar inclination.

Strengths

• Data processed using the standardized PyFluxPro (v3.4.17) pipeline, which produces a final, gap-filled product.
• Provides long-term monitoring data from a station established in December 2008, part of the FNQ Rainforest SuperSite and TERN network.
• Site is in a highly biodiverse, complex mesophyll vine forest with detailed site characteristics: 94 species in the core 1 Ha, average tree height of 22 m, and elevation of 90 m.

Limitations

• The early years (2009-2012) contain several data gaps, reducing temporal continuity for that period.
• Persistent shadowing of radiometric equipment causes artifacts in radiation measurements, visible as reductions in downwelling radiation with solar inclination.
• Sample data and specific data volume (rows/columns) are unavailable, limiting pre-download assessment of structure and completeness.
