Description
Encompassing eddy covariance measurements of energy and mass exchange between the surface and atmosphere in a seasonally flooded tropical woodland. Measurements include heat, water vapor, carbon dioxide fluxes, temperature, humidity, wind, radiation, soil heat flux, and soil moisture. The site features a 15m instrument mast and vegetation dominated by Oryza rufipogon, Pseudoraphis spinescens, and Eleocharis dulcis.
Use Cases
Analyze seasonal patterns in carbon dioxide fluxes relative to soil moisture content and rainfall in a tropical wetland.
Model latent and sensible heat fluxes using measurements of net radiation, temperature, humidity, and wind speed above the canopy.
Investigate relationships between leaf area index (LAI) measurements and vegetation optical properties with ecosystem gas exchange.
Correlate soil heat flux data with incoming and reflected shortwave radiation to study surface energy partitioning.
Strengths
Includes a comprehensive suite of micrometeorological and biophysical measurements such as eddy fluxes, radiation, soil properties, and leaf-scale physiology.
Site characterization provides specific environmental context: 15m instrument mast, 4m elevation, and mean annual precipitation of 1411mm.
Dataset is complemented by ancillary data including airborne LiDAR and hyperspectral remote sensing from September 2008.
Limitations
The temporal coverage and total number of data records (rows) are not specified, limiting assessment of dataset scale and time-series analysis potential.
Data is provided in HTML and PNG formats, which are non-standard for quantitative analysis and may require significant extraction and preprocessing.
Geographic specificity is high (single site at Fogg Dam), limiting generalizability to other tropical wetland ecosystems.
