This dataset consists of measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer in wet sclerophyll forest using eddy covariance techniques. <br /> <br /> The Tumbarumba flux station is located in the Bago State Forest in south eastern New South Wales. It was established in 2000 and is managed by CSIRO Marine and Atmospheric Research. The forest is classified as wet sclerophyll, the dominant species is Eucalyptus delegatensis, and average tree height is 40m. Elevation of the site is 1200m and mean annual precipitation is 1000mm. The Bago and Maragle State Forests are adjacent to the south west slopes of southern New South Wales and the 48,400 ha of native forest have been managed for wood production for over 100 years. The instrument mast is 70m tall. 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, wind speed, wind direction, rainfall, incoming and reflected shortwave radiation and net radiation. Profiles of temperature, humidity and CO2 are measured at seven levels within the canopy. Soil moisture content is measured using Time Domain reflectometry, while soil heat fluxes and temperature are also measured. Hyper-spectral radiometric measurements are being used to determine canopy leaf-level properties. The Tumbarumba flux station is supported by TERN and the DCCEE through the ACCSP. <br />For additional site information, see https://www.tern.org.au/tern-observatory/tern-ecosystem-processes/tumbarumba-wet-eucalypt-supersite/. <br />This data is also available at http://data.ozflux.org.au .<br />

This dataset consists of measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer in southeast of Emerald, Queensland, using eddy covariance techniques. <br /> <br /> The Arcturus greenhouse gas (GHG) monitoring station was established in July 2010, 48 km southeast of Emerald, Queensland, with flux tower measurements starting in June 2011 until early 2014. The station was part of a collaborative project between Geoscience Australia (GA) and CSIRO Marine and Atmospheric Research (CMAR). Elevation of the site was approximately 170m asl and mean annual precipitation was 572mm. The tower bordered 2 land use types split N-S: To the west lightly forested tussock grasslands; To the east crop lands, cycling through fallow periods.The instruments were installed on a square lattice tower with an adjustable pulley lever system to raise and lower the instrument arm. The tower was 5.6m tall with the instrument mast extending a further 1.1m above, totalling a height of 6.7m. Fluxes of heat, water vapour, methane and carbon dioxide were measured using the open-path eddy flux technique. Supplementary measurements above the canopy included temperature, humidity, windspeed, wind direction, rainfall, and the 4 components of net radiation. Soil heat flux, soil moisture and soil temperature measurements were also collected. <br /> For additional site information, see http://www.ozflux.org.au/monitoringsites/arcturus/index.html.<br /><br /> This data is also available at http://data.ozflux.org.au .

This dataset consists of measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer in a pastoral area using eddy covariance techniques.<br /><br /> The flux station is located within an area of dryland agriculture. The surrounding area is dominated by broadacre farming practices. The vegetation cover is predominantly pasture. Elevation of the site is close to 330 m. Climate information comes from the nearby Pingelly BoM AWS station 010626 (1991 to 2016) and shows mean annual precipitation is approximately 445 mm with highest rainfall in June and July of 81 mm each month. Maximumum and minuimum annual rainfall is 775 and 217 mm, respectively. Maximum temperatures range from 31.9°C (in Jan) to 15.4°C (in July), while minimum temperatures range from 5.5°C (in July) to 16.0 °C (in Feb).<br /><br />This data is also available at http://data.ozflux.org.au .

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 forest is classed as a tall, wet sclerophyll forest, and the dominant <em>Eucalyptus Regnans</em> or Mountain Ash trees have an average canopy height of 75m. The site contains a chronosequence of (20, 80 and 300) stand ages that were established during fires occurring over the last 300 years. The area is assigned the IUCN Category II (National Parks) of the United Nations’ list of National Parks and protected areas, which means that park is primarily managed for ecosystem conservation. The catchment area is dominated by Mountain Ash, the world’s tallest flowering plant (angiosperm). Trees can reach heights of more than 90 metres in areas with high rainfall and fertile soil. Mountain ash forests are confined to the cool mountain regions with elevations ranging from 460 - 1100m and average rainfalls of 1100-2000mm. These trees are well distributed throughout Victoria’s Central Highlands including the Otway Ranges and Strzlecki Ranges; they are also found in Tasmania. The catchment area contains a portion of the Mt Disappointment range, the Divide and the headwaters of Wallaby Creek and Silver Creek, and much of the slopes are characterised as flat to moderate.<br /><br /> The station itself is located within an old growth stand with individual trees as old as 300 years. Below the dominant canopy lies a temperate rainforest understorey consisting of <em>Pomaderris aspera</em> and <em>Olearia argophylla</em> species, which are 10-18 metres tall. The lower layers of vegetation are dominated by tree ferns (<em>Cyathea australis</em> and <em>Dicksonia antartica</em>) and extensive tracts of rosette and rhizonic ferns (<em>Polystichum proliferum</em> and <em>Blechnum wattsii</em>) as well as Acacia trees. <br /> <br /> The major soil type within the forest is krasnozemic soils, which are friable red/brown, with high amounts of organic matter in the upper 20 – 30cm. However, the composition of krasnozemic soils is not homogenous, but rather a variation with altitude can be observed; lower altitudes inhabit grey-yellow podsolised soils compared to higher altitudes of the Kinglake and Hume plateau where the soil composition is krasnozemic loams. The clay content of these soils increases with depth until at least 200 cm deep, where after a transition soils contain rock fragments. The elevation is approximately 720 metres.<br /><br /> The original station was destroyed in February 2009 by bushfires. Before the bushfire, the main mast stood at 110m. In March 2010, a replacement station was established and sat at a height of 5m. Data from the site has been recorded from May 2010 onwards. As the station is relatively new, the post fire instrumentation is currently not as diverse when compared to the pre-fire instrumentation. The climate of the study area is classified as a cool, temperate zone, with the highest temperatures occurring during the summer months of December – February (13.8 – 22.5°C), whilst the coolest temperatures are experienced in May and August (4.7 – 9.2°C). Average annual precipitation is 1209mm, with a maximum rainfall occurring in June (Ashton, 2000). The study site experiences foggy conditions after sunset during autumn and winter.<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 (v3.4.15) 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>This is a topographically flat area, primarily comprised of the following soil types: sandy loams, scattered clays, red brown earths, transitional red brown earth, sands over clay and deep sands. Stream valleys and layered soil and sedimentary materials are found across the landscape.</br> <br>The flux station tower extends to 20&nbsp;m, however flux measurements are recorded from slightly lower than this. Mean annual precipitation from the nearby Bureau of Meteorology is 465&nbsp;mm. Maximum temperatures ranged from 16.6&nbsp;°C (in July) to 37.4&nbsp;°C (in January), while minimum temperatures ranged from 11.8&nbsp;°C (in July) to 29.0&nbsp;°C (in January). Maximum temperatures varied on a seasonal basis by approximately 20.8&nbsp;°C and minimum temperatures by 17.2&nbsp;°C.</br> <br>The site is within a wider research area (60 x 60&nbsp;km) that supports a network of flux stations, which have been in operation since late 2001.</br>
