Sturt Plains FLUXNET Release 2026_r1

<p>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 as described by Isaac et al. (2017) for the quality control and post-processing steps. The final, gap-filled product containing Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER) has been produced using the ONEFlux software as described in Pastorello et al (2020). This data set has been produced as part of the FLUXNET Shuttle project.</p> <p>The Sturt Plains flux station is located approximately 280km north of Tennant Creek, Northern Territory (GPS coordinates: -17.1507, 133.3502).</p> <p>The flux tower site is 280km north of Tennant Creek, amongst a low lying plain dominated by Mitchell Grass (gen. Astrebla). Elevation of the site is close to 250m and mean annual precipitation at a nearby Bureau of Meteorology site is 640mm<br />Maximum temperatures range from 28.4&deg;C (in June/ July) to 39.1&deg;C (in December), while minimum temperatures range from 11.2&deg;C (in July) to 24.4&deg;C (in December).<br />The instrument mast is 5 meters 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 />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.</p>
