    This data release consists of flux tower measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer in semi-arid eucalypt woodland using eddy covariance techniques. It been processed using PyFluxPro (v3.3.3) as described in Isaac et al. (2017), <a href="https://doi.org/10.5194/bg-14-2903-2017">https://doi.org/10.5194/bg-14-2903-2017</a>. PyFluxPro takes data recorded at the flux tower and process this data to a final, gap-filled product with Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER). For more information about the processing levels, see <a href="https://github.com/OzFlux/PyFluxPro/wiki">https://github.com/OzFlux/PyFluxPro/wiki</a>. <br /> <br /> The Calperum Chowilla site was established in July 2010 and is managed by the University of Adelaide (UA), 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 stabilised by mallee (multi-stemmed Eucalypt trees) and various shrubs. It is a semi-arid environment fringing the River Murray floodplains of the Riverland.<br />For additional site information, see http://www.landscapescience.org/. <br /><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 (v3.5.0) 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>Alice Springs Mulga flux station is located on Pine Hill cattle station, near Alice Springs in the Northern Territory. The woodland is characterized by the <i>Acacia aneura</i> canopy, which is 6.5&nbsp;m tall on average. Elevation of the site is 606&nbsp;m above sea level, and the terrain is flat. Mean annual precipitation at the nearby (45&nbsp;km distant) Bureau of Meteorology station is 305.9&nbsp;mm but ranges between 100&nbsp;mm in 2009 to 750&nbsp;mm in 2010. Predominant wind directions are from the southeast and east. The extent of the woodland is 11&nbsp;km to the east of the flux station and 16&nbsp;km to the south. The soil is red sandy clay (50:50 sand:clay) overlying a 49&nbsp;m deep water table. Pine Hill Station is a functioning cattle station that has been in operation for longer than 50 years. The instrument mast is 13.7&nbsp;m tall. Fluxes of heat, water vapour and carbon are measured using the open-path eddy covariance technique at 11.6&nbsp;m. Supplementary measurements above the canopy include temperature and humidity (11.6&nbsp;m), windspeed and wind direction (9.25&nbsp;m), downwelling and upwelling shortwave and longwave radiation (12.2&nbsp;m). Precipitation is monitored in a canopy gap (2.5&nbsp;m). Supplementary measurements within and below the canopy include barometric pressure (1&nbsp;m), wind speed (2&nbsp;m, 4.25&nbsp;m and 6.5&nbsp;m), and temperature and humidity (2&nbsp;m, 4.25&nbsp;m and 6&nbsp;m). Below ground soil measurements are made in bare soil, mulga, and understory habitats and include ground heat flux (0.08&nbsp;m), soil temperature (0.02&nbsp;m – 0.06&nbsp;m) and soil moisture (0 – 0.1&nbsp;m, 0.1 – 0.3&nbsp;m, 0.6 – 0.8&nbsp;m and 1.0 – 1.2&nbsp;m). Ancillary measurements include soil water and carbon fluxes, leaf water potential, leaf gas exchange, stem basal area, stem growth, litter production, leaf area index, stem hydraulic conductance, and carbon and water stable isotope ratios. <br />

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 site is classified as box woodland, dominated by two main eucalypt species: <em>Eucalyptus microcarpa</em> (grey box) and <em>Eucalyptus leucoxylon</em> (yellow gum). The site has an elevation of 165&nbsp;m. Mean annual precipitation measured by the nearby Bureau of Meteorology site is 558&nbsp;mm. Maximum temperatures range from 12.6&nbsp;°C (in July) to 29.8&nbsp;°C (in January), while minimum temperatures range from 3.2&nbsp;°C (in July) to 14.2&nbsp;°C (in February). Maximum temperatures vary on a seasonal basis by approximately 17.2&nbsp;°C and minimum temperatures by 11.0&nbsp;°C.</br> <br>The instrument mast is 36&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, incoming and reflected shortwave radiation and net radiation are measured above the canopy. Soil heat fluxes are measured and soil moisture content is gathered using time domain reflectometry.</br>

Maximum temperatures varied on a seasonal basis by approximately 4.3°C and minimum temperatures by 9.0°C.<br /> <br /> The instrument mast was 15m 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 were measured above the canopy. Soil heat fluxes were measured and soil moisture content was gathered using time domain reflectometry.<br /> Ancillary measurements taken at the site include LAI, leaf-scale physiological properties (gas exchange, leaf isotope ratios, N and chlorophyll concentrations), vegetation optical properties and soil physical properties. Airborne based remote sensing (Lidar and hyperspectral measurements) was carried out across the transect in September 2008. <br />
