Eddy Covariance Flux Measurements in Australian Open Woodland Savanna

Measurements of energy and mass exchange between the surface and atmosphere in an open woodland savanna using eddy covariance techniques. The site features a 23m instrument mast and collects data on heat, water vapor, carbon dioxide, temperature, humidity, wind, rainfall, and radiation. It is provided by the Terrestrial Ecosystem Research Network.

Use Cases

• Analyze the relationship between net radiation measurements and soil heat fluxes to model surface energy balance.
• Investigate seasonal patterns in carbon dioxide exchange using eddy flux data across wet and dry seasons.
• Model evapotranspiration by correlating water vapor flux measurements with soil moisture content from time domain reflectometry.
• Study microclimate by examining temperature and humidity profiles above the 14-16m canopy.
• Assess the impact of rainfall on soil moisture and subsequent heat, water vapor, and carbon dioxide fluxes.

Strengths

• Data collected using the established eddy covariance technique for measuring surface-atmosphere exchange.
• Site characteristics are well-documented, including average tree height of 14-16m, elevation of 64m, and mean annual precipitation of 1750mm.
• Instrumentation is detailed, with a 23m tall mast and measurements of multiple variables like radiation, soil heat flux, and wind.

Limitations

• The dataset's temporal coverage and total number of observations (rows) are not specified.
• Data is provided in HTML and PNG formats, which are not standard for quantitative analysis and may require extraction and conversion.
• The license is listed as 'notspecified', which creates uncertainty for commercial or redistribution use.
