This release consists of flux tower measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer using eddy covariance techniques. Data were processed using PyFluxPro (v3.4.17) as described by Isaac et al. (2017). PyFluxPro produces a final, gap-filled product with Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER).
The site is woodland savanna with an overstory co-dominated by tree species Eucalyptus tetrodonta, Corymbia latifolia, Terminalia grandiflora, Sorghum sp. and Heteropogon triticeus. Average canopy height measures 16.4 m. Elevation of the site is close to 110 m and mean annual precipitation at a nearby Bureau of Meteorology site is 1,170 mm. Maximum temperatures range from 31.2 °C (in June) to 37.5 °C (in October), while minimum temperatures range from 12.6 °C (in July) to 23.8 °C (in January). Maximum temperatures range seasonally by 6.3 °C and minimum temperatures by 11.2 °C. The instrument mast is 23 m tall. Heat, water vapour and carbon dioxide measurements are taken using the open-path eddy flux technique. Temperature, humidity, wind speed, wind direction, rainfall, incoming and reflected shortwave radiation and net radiation are measured above the canopy.Ancillary measurements taken at the site include LAI, leaf-scale physiological properties (gas exchange, leaf isotope ratios, nitrogen and chlorophyll concentrations), vegetation optical properties and soil physical properties. Airborne based remote sensing (Lidar and hyperspectral measurements) was carried out across the site in September 2008.
