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.

Average canopy height measures 16.4 m. <br />Elevation of the site is close to 110m and mean annual precipitation at a nearby Bureau of Meteorology site is 1170mm. Maximum temperatures range from 37.5°C (in October) to 31.2°C (in June), 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. <br /><br />The instrument mast is 23 meters tall. Heat, water vapour and carbon dioxide measurements are taken using the open-path eddy flux technique.

In the NT, savanna ecosystems are largely intact in terms of tree cover, with only modest levels of land use change. Despite this, there is evidence of a loss of biodiversity, most likely due to shifts in fire regimes and a loss of patchiness in the landscape. Approximately 40% of the savanna burn every year and understanding fire impacts on fauna and flora is essential for effective land management. <br /><br />

The woodland is characterized by the Acacia aneura canopy, which is 6.5m tall on average. Elevation of the site is 606m above sea level, and the terrain is flat. Mean annual precipitation at the nearby (45km distant) Bureau of Meteorology station is 305.9mm but ranges between 100mm in 2009 to 750mm in 2010. Predominant wind directions are from the southeast and east.The extent of the woodland is 11km to the east of the flux station and 16km to the south. The soil is red sandy clay (50:50 sand:clay) overlying a 49m 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 13.7m tall. Fluxes of heat, water vapour and carbon are measured using the open-path eddy covariance technique at 11.6m. Supplementary measurements above the canopy include temperature and humidity (11.6m), windspeed and wind direction (9.25m), downwelling and upwelling shortwave and longwave radiation (12.2m). Precipitation is monitored in a canopy gap (2.5m). Supplementary measurements within and below the canopy include barometric pressure (1m), wind speed (2m, 4.25m and 6.5m), and temperature and humidity (2m, 4.25m and 6m). Below ground soil measurements are made in bare soil, mulga, and understory habitats and include ground heat flux (0.08m), soil temperature (0.02m – 0.06m) and soil moisture (0 – 0.1m, 0.1 – 0.3m, 0.6 – 0.8m and 1.0 – 1.2m). 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. The site was established in September 2010 in conjunction with the Woodforde River NGCRT Superscience Site and is managed by the University of Technology Sydney.<br />For additional site information, see https://www.tern.org.au/tern-observatory/tern-ecosystem-processes/alice-mulga-supersite/ <br /><br />

Stream valleys and layered soil and sedimentary materials are found across the landscape. <br /><br /> The flux station tower extends to 20m, however flux measurements are recorded from slightly lower than this. Mean annual precipitation from a nearby Bureau of Meteorology site measured 465 mm. Maximum temperatures ranged from 37.4°C (in January) to 16.6°C (in July), while minimum temperatures ranged from 29.0°C (in January) to 11.8°C (in July). Maximum temperatures varied on a seasonal basis by approximately 20.8°C and minimum temperatures by 17.2°C. <br /> The site is within a wider research area (60 x 60 km) that supports a network of flux stations, which have been in operation since late 2001 onwards.<br /><br />
