Cow Bay FLUXNEXT Release: Carbon Flux Measurements from a Tropical Rainforest Tower

Cow Bay FLUXNEXT Release 2026_r1 provides flux tower measurements of energy and mass exchange between a tropical rainforest surface and the atmosphere. The data were processed using PyFluxPro and ONEFlux software to produce a final, gap-filled product containing Net Ecosystem Exchange partitioned into Gross Primary Productivity and Ecosystem Respiration. This dataset is part of the FLUXNET Shuttle project and is managed by James Cook University.

Use Cases

• Modeling Net Ecosystem Exchange (NEE) dynamics in a lowland tropical rainforest based on the gap-filled product.
• Partitioning carbon flux into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER) for ecosystem studies.
• Analyzing the impact of seasonal rainfall patterns on carbon exchange, given the site's average annual rainfall of 3700 mm.
• Studying flux measurements in complex terrain, as the site's fetch area is described as very complex.

Strengths

• Data collection commenced in December 2008, providing a long-term record.
• Processing follows established methodologies: PyFluxPro (Isaac et al., 2017) and ONEFlux (Pastorello et al., 2020).
• Site metadata is detailed, including precise GPS coordinates (-16.238189, 145.427150), elevation (86 m), and forest canopy height (25 m).
• Annual average rainfall is quantified at around 3700 mm with a described seasonal pattern.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
• The site's complex terrain may introduce measurement challenges not fully quantified in the metadata.
