Ecosystem flux data from the Alice Springs site, Northern Territory.The Alice Springs Mulga flux station is located on Pine Hill cattle station, near Alice Springs in the Northern Territory.The woodland is characterised by a mulga (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).Belowground 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.
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 ecocloud Platform provides unprecedented access to datasets from hundreds of publishers across Australia in a single interface, including key ecoscience publishers such as ALA, TERN and IMOS. It then connects this data with common analysis tools like RStudio, Jupyter Notebooks and Virtual Desktops running tools like Kepler, KNIME, QGIS, Biodiverse, marcoecoDesktop, Panoply, Jupyter lab, RStudio and file sharing applications Dropbox and ownCloud. Curated data is also available through discipline-specific workflows like the BCCVL and Biodiverse, all of which also connect users to Australia’s national cloud computing infrastructure. ecocloud also includes an innovative training and skills development program (ecoEd) to help drive a skilled workforce of students, researchers, government practitioners and industry professionals working across the domain.
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.
This service provides access to ecosystem flux data from Ridgefield in Western Australia. The site is is located in dryland agriculture dominated by broadacre farming practices, 12km west of Pingelly, near Perth.
The Daly River Uncleared flux tower site is located in the Douglas River Daly River Esplanade Conservation area, approximately 60 km south west of Pine Creek, Northern Territory (GPS coordinates: -14.1592, 131.3881).The flux tower site is classified as a Woodland savanna. The overstory is co dominated by tree species E. tetrodonta, C. latifolia, Terminalia grandiflora, Sorghum sp. and Heteropogon triticeus. Average canopy height measures 16.4 m. 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.The instrument mast is 23 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, incoming and reflected shortwave radiation and net radiation are measured above the canopy.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.
Ecosystem flux data from the Warra Flux Tower, Tasmania.The flux tower is installed in a stand of tall, mixed-aged E. obliqua forest (77 and >250 years-old) with a rainforest understorey and a dense man-fern (Dicksonia antarctica) ground-layer, on a small flat of elevation 100 m adjacent to the Huon River.The climate of Warra is classified as temperate with a mild summer and no dry season. Mean annual precipitation is 1700 mm with a relatively uniform seasonal distribution. Summer temperatures peak in January (min. 8.4°C – max 19.2°C) with winter temperatures reaching their lowest in July (min 2.6°C – max 8.4°C).Eucalyptus obliqua forests dominate the vegetation below 650 m where they exist as fire-maintained communities. On fertile soils these forests attain mature heights in excess of 55m: the tallest E. obliqua within the LTER reaches a height of 90m. The understorey vegetation progresses from wet sclerophyll (dominated by Pomaderris apatala and Acacia dealbata) to rainforest (dominated by Nothofagus cunninghamii, Atherosperma moschatum, Eucryphia lucida and Phyllocladus aspleniifolius) with increasing time intervals between fire events.The site supports prodigous quantities of coarse woody debris as is characteristic of these fire-maintained eucalypt forests on fertile sites in southern Tasmania. The soil at the flux site is derived from Permian mudstone and has a gradational profile with a dark brown organic clayey silt topsoil overlying a yellow brown clay.The instruments are mounted at the top of an 80m tall guyed steel lattice tower. Supplementary measurements above the canopy include temperature, humidity, windspeed, wind direction, rainfall, incoming and reflected shortwave radiation and net radiation. An open-path gas analyser (EC150) was replaced by a closed-path gas analyser (EC155) at the end of Jan 2015.Soil moisture content is measured using Time Domain reflectometry, while soil heat fluxes and temperature are also measured.Micro-meteorology (CO2, H2O, energy fluxes), meteorology (temp, humidity, wind speed and direction, rainfall) taken from the Warra Flux Site from 2013 to late 2016. Data incomplete due to ongoing problems since changing the open-path IRGA to a closed path system (CPEC200) during 2015. Soil data (moisture, heat flux, temp) complete for time period.Data processed to L3 with OzFluxQC version 2.8.4
The Riggs Creek flux station is located in Goulburn-Broken catchment in North-Eastern Victoria. The flux tower site is located within an area of dryland agriculture.
