Flux Tower Measurements from a Seasonally Flooded Wetland

Flux tower measurements of energy and mass exchange between a wetland surface and the atmosphere using eddy covariance techniques. Data were processed with PyFluxPro to produce gap-filled products including Net Ecosystem Exchange (NEE), Gross Primary Productivity (GPP), and Ecosystem Respiration (ER). The site is a wetland with seasonal flooding, featuring vegetation like Oryza rufipogon and Pseudoraphis spinescens.

Use Cases

• Model wetland carbon dynamics by analyzing gap-filled Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER).
• Study energy balance in a seasonally flooded ecosystem using measurements of incoming/reflected shortwave radiation, net radiation, and soil heat fluxes.
• Analyze the impact of local climate on ecosystem fluxes using ancillary data on temperature, humidity, wind speed, and mean annual precipitation (1411 mm).
• Investigate vegetation-atmosphere interactions by correlating flux data with ancillary measurements of Leaf Area Index (LAI) and leaf-scale physiological properties.

Strengths

• Data processed using the established PyFluxPro (v3.4.17) software to produce a final, gap-filled product.
• Includes a comprehensive suite of micrometeorological measurements (temperature, humidity, wind, radiation, soil heat fluxes, soil moisture).
• Site characterization provides specific environmental context, including mean annual precipitation of 1411 mm and seasonal temperature ranges (max 31.3-35.6°C, min 14.9-23.9°C).
• Supported by ancillary ecological data including LAI, leaf physiology, vegetation optical properties, and historical airborne remote sensing (Lidar, hyperspectral).

Limitations

• The specific number of data rows (time series records) and columns (measured variables) is not provided.
• Primary data formats are HTML and PNG, which may not be the most convenient for direct quantitative analysis compared to CSV or NetCDF.
• The temporal coverage of the flux measurements is not explicitly stated in the provided description.
