    This service provides access to ecosystem flux data from the Wombat State Forest in Victoria. The site is a secondary re-growth forest that was last harvested in 1980. Dominant tree species are Eucalyptus obliqua (messmate stringybark), Eucalyptus radiata (narrow leaf peppermint) and Eucalyptus rubida (candlebark) with an average canopy height of 25m.

    The Sturt Plains flux station is located approximately 280km north of Tennant Creek, Northern Territory. It was established in August 2008 and is managed by Monash University external and Charles Darwin University. The Sturt Plains OzFlux Site is located on 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.Maximum temperatures range from 28.4°C (in June/ July) to 39.1°C (in December), while minimum temperatures range from 11.2°C (in July) to 24.4°C (in December).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.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.

    The Whroo flux station is located approximately 45km south west of Shepparton, Victoria.It was established in October 2011 and is managed by The University of Western Australia.The flux tower site was classified as box woodland, dominated by two main Eucalypt species: Eucalyptus microcarpa (Grey Box) and Eucalyptus leucoxylon (Yellow Gum). Elevation of the site is close to 165 m and mean annual precipitation from a nearby Bureau of Meteorology site measured 558 mm. Maximum temperatures ranged from 29.8oC (in January) to 12.6oC (in July), while minimum temperatures ranged from 14.2oC (in February) to 3.2oC (in July). Maximum temperatures varied on a seasonal basis by approximately 17.2oC and minimum temperatures by 11.0oC.The instrument mast is 36m 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.

    The Gingin flux station is located in coastal heath Banksia woodland on the Swan Coastal Plain 70km north of Perth, Western Australia: (elevation: 51m), and 2km south of the University of Western Australia International Gravity Wave Observatory. The site was established in June 2011 by CSIRO and is now managed by Edith Cowan University Centre for Ecosystem Management. The site is a natural woodland of high species diversity. The overstorey is dominated by Banksia spp. mainly B. menziesii, B. attenuata, and B. grandis with a height of around 7m and leaf area index of about 0.8. There are occasional stands of eucalypts and acacia that reach to 10m and have a denser foliage cover. There are many former wetlands dotted around the woodland, most of which were inundated all winter and some had permanent water 30 years ago. The watertable has now fallen below the base of these systems and they are disconnected and are no longer permanently wet. The fine sediments, sometimes diatomaceous, hold water and they have perched watertables each winter. There is a natural progression of species accompanying this process as they gradually become more dominated by more xeric species. The soils are mainly Podosol sands, with low moisture holding capacity. Field capacity typically about 8 to 10%, and in summer these generally hold less than 2% moisture. The watertable is at about 8.5 m below the surface, and a WA Dept of water long-term monitoring piezometer is near the base of the tower. The instrument mast is 14m tall, with the eddy covariance instruments mounted at 14.8m. Fluxes of carbon dioxide, water vapour and heat are quantified with open-path eddy covariance instrumentation. Ancillary measurements include temperature, air humidity, wind speed and direction, precipitation, incoming and outgoing shortwave radiation, incoming and outgoing long wave radiation, incoming total and diffuse PAR and reflected PAR. Soil water content and temperature are measured at six soil depths. Surface soil heat fluxes are also measured. A COSMOS Cosmic ray soil moisture instrument is installed, along with a logged piezometer, and nested piezometers installed with short screens for groundwater profile sampling. To monitor the watertable gradient, piezometers will be installed 500 m esat and west of the tower.

    Flux measurements from the Cow Bay site, Far North Queensland.The Cow Bay flux station was located in the Daintree forest at the Daintree Discovery Centre, Cow Bay, 100km north of Cairns in Far North Queensland. It was established in December 2008 and managed by James Cook University.The forest is classified as complex mesophyll vine forest, there are 94 species in the core 1Ha, and average tree height is 22m. Elevation of the site is 90m and mean annual precipitation is 3935mm. The Daintree Rainforest is one of the most biodiverse forests in Australia.The instruments are mounted on a walk-up tourist tower at 35m. Fluxes of heat, water vapour and carbon dioxide are measured using the open-path eddy flux technique. Supplementary measurements above the canopy include temperature, humidity, windspeed, wind direction, rainfall, incoming and reflected shortwave radiation and net radiation.The early years 2009 - 12 had several data gaps. Shadowing of the radiometric equipment continues to cause artifacts on the radiometers - these can be seen as reduction in downwelling radiation with solar inclination. We are currently working on a hardware solution.The site is part of the FNQ Rainforest SuperSite : associated with the Daintree node, which is part of the TERN Australian SuperSite Network (ASN). The site was co-funded by the Daintree Discovery Centre and the Terrestrial Ecosystem Research Network. Past support was from the Department of Environment and Heritage - Marine and Tropical Sciences Research Facility Project 5ii.2. Climate Change: Scaling from trees to ecosystems.
