    The record contains leaf traits information measured on <i>Eucalyptus tereticornis</i> trees from the EucFACE site in Cumberland Plain in 2012. Data on tree height, leaf dry mass per unit leaf area (LMA), stomatal conductance to water vapour (<i>gs</i>), light saturated leaf net CO<sub>2</sub>assimilation rates (A<sub>sat</sub>) and maximum net CO<sub>2</sub> exchange rate at light- and CO<sub>2</sub>-saturation (A<sub>max</sub>) are provided.

    <br>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 (v3.5.0) 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).</br> <br> The Calperum Chowilla site was established in July 2010 and is managed by the University of Adelaide, coordinated by Prof Wayne Meyer and Prof David Chittleborough of the Landscape Futures Program as part of the Environment Institute. This is a former sheep grazing property that has been destocked and is being managed as a conservation area in this type of ecosystem. The landscape is flat with a series of low east–west sand dunes. The dunes are remnants of a previous dry era and are mostly now stabilized by mallee (multi-stemmed Eucalypt trees) and various shrubs. It is a semi-arid environment fringing the River Murray floodplains of the Riverland. <br>

    <br>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).</br> <br>The flux station site is located within an area of dryland agriculture. The surrounding area is dominated by broadacre farming practices. The vegetation cover is predominantly pasture. Elevation of the site is close to 152&nbsp;m and mean annual precipitation at a nearby Bureau of Meteorology site measures 650&nbsp;mm. Maximum temperatures range from 12.3&nbsp;°C (in July) to 29.7&nbsp;°C (in February), while minimum temperatures range from 10.4&nbsp;°C (in July) to 26.8&nbsp;°C (in February).</br> <br>The instrument mast is 4&nbsp;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 and net radiation are measured. Soil heat fluxes are measured and soil moisture content is gathered using time domain reflectometry.</br>
