Adelaide River Flux Data Collection

This dataset consists of measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer in woody savanna using eddy covariance techniques. The ecosystem was dominated by Eucalyptus tectifica and Planchonia careya . Elevation of the site was close to 90m and mean annual precipitation at a nearby Bureau of Meteorology site was 1730mm. Maximum temperatures ranged from 31.4°C (in June) to 36.8°C (in October) while minimum temperatures range from 16.2°C (in July) to 25.1°C (in December). Maximum temperature varied seasonally by approximately 5.4°C and minimum temperatures varied by approximately 8.9°C.The instrument mast was 15 meters tall. Heat, water vapour and carbon dioxide measurements were taken using the open-path eddy flux technique. Temperature, humidity, wind speed, wind direction, rainfall, incoming and reflected shortwave radiation and net radiation were measured above the canopy. Soil heat fluxes are measured and soil moisture content was gathered using time domain reflectometry.
