Flux Tower Measurements of Greenhouse Gas Exchange in a Tropical Savanna Conversion

Encompassing flux tower measurements of energy and mass exchange between the surface and atmosphere using eddy covariance techniques. The data were processed with PyFluxPro (v3.5.0) to produce a final, gap-filled product, including Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER). The flux station was established in August 2011 in a tropical savanna site that was later converted to watermelon farmland.

Use Cases

• Analyze the temporal dynamics of Net Ecosystem Exchange (NEE) to quantify the carbon balance shift during the conversion from tropical savanna to watermelon farmland.
• Partition NEE into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER) to study the components of ecosystem carbon cycling in an agricultural landscape.
• Use eddy covariance flux measurements to model greenhouse gas exchange between the land surface and the atmospheric boundary-layer.
• Investigate the impact of land-use change from forest to farmland on energy and mass exchange fluxes over a multi-year period.

Strengths

• Data processed using the standardized PyFluxPro (v3.5.0) pipeline, which produces a final, gap-filled product.
• Provides long-term temporal coverage, with measurements starting in August 2011 and continuing through a land-use conversion experiment.
• Focuses on a specific, documented land-use change scenario: the conversion of tropical savanna to watermelon production farmland.

Limitations

• The specific number of data rows, columns, and file size are unknown, limiting assessment of dataset scale and granularity.
• Data is delivered in HTML and PNG formats, which are not standard for quantitative analysis and may require extraction or conversion.
• The license is unspecified, which may create uncertainty for users regarding permissible redistribution and commercial use.
