    <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 (v3.5.0) 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>Robson Creek site is part of the Far North Queensland (FNQ) Rainforest Site along with affiliated monitoring sites at Cape Tribulation (Daintree Rainforest Observatory) and Cow Bay (Daintree Discovery Centre). The flux station is located at the foothills of the Lamb Range, part of the Wet Tropics World Heritage Area, and north-west of a 25&nbsp;ha census plot established by CSIRO in 2012.</br> <br>The forest is classified as Regional Ecosystem (RE) 7.3.36a, complex mesophyll vine forest (Queensland Government, 2006). There are 211 species in the adjacent 25&nbsp;ha plot, and average tree height is 28&nbsp;m, ranging from 23 to 44&nbsp;m. Elevation of the site is 711&nbsp;m and mean annual precipitation is 2000&nbsp;mm. The upland rainforests of the Atherton Tablelands are some of the most biodiverse and carbon dense forests in Australia. The landform of the 25&nbsp;ha plot which is in the dominant wind direction from the station is moderately inclined with a low relief, a 30&nbsp;m high ridge running north/south through the middle of the plot and a 40&nbsp;m high ridge running north/south on the eastern edge of the plot.</br> <br>The instruments are mounted on a free standing station at 40&nbsp;m. 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.</br> <br>Note: Level 3 data for 2015 - 2018 were updated in 2018 correcting a rainfall issue in 2015 and a wind direction issue 2016 - 2018. A data gap from 2019-02-14 to 2019-02-21 was due to a major power supply failure.</br>

    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 site is located on a low lying plain dominated by Mitchell Grass (<em>gen. Astrebla</em>). 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).<br /><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 /><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. Biomass Harvest - mean live biomass: 0.00 gm-2 (standard error: 0.00) , mean standing dead biomass: 163.42 gm-2 (standard error: 16.73), mean litter biomass: 148.99 gm-2 (standard error: 21.32), total mean biomass: 312.40 gm-2 (standard error: 30.80), Soil- Clay: 14.47% (volume <1µm), Silt: 51.23% (volume <1µm), Sand: 34.30% (volume <1µm), Sand (>1 µm): 1.02% (total weight).<br /><br />

    This dataset consists of measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer from an Almond Orchard in South Australia's Riverland, using eddy covariance techniques. <br /> <br /> The Loxton site was established in August 2008 and decommissioned in June 2009. The orchard was divided into 10 ha blocks (200 m by 500 m with the long axis aligned north–south) and the flux tower was situated at 34.47035°S and 140.65512°E near the middle of the northern half of a block of trees. The topography of the site was slightly undulating and the area around the tower had a slope of less than 1.5°. The orchard was planted in 2000 with an inter-row spacing of 7 m and a within row spacing of 5 m. Tree height in August 2008 was 5.5 m. The study block consists of producers, Nonpareil, planted every other row, and pollinators planted as alternating rows of Carmel, Carmel and Peerless, and Carmel and Price. All varieties were planted on Nemaguard rootstock. All but 31 ha of the surrounding orchard was planted between 1999 and 2002. Nutrients were applied via fertigation. Dosing occurred between September and November and in April with KNO3, Urea, KCl, and NH4NO3 applied at annual rates of 551, 484, 647, and 113 kg/ha, respectively. The growth of ground cover along the tree line was suppressed with herbicides throughout the year. Growth in the mid-row began in late winter and persisted until herbicide application in late November. <br> The research was supported with funds from the National Action Plan for Salinity via the Centre for Natural Resource Management, and the River Murray Levy.<br />This data is also available at http://data.ozflux.org.au . <br>
