<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 /> The flux station was established in August 2011 while the site supported tropical savanna. The site was part of a deforestation experiment measuring greenhouse gas exchange during conversion of forest to farmland. The land was being cultivated for watermelon production from 2013.<br /><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 (v3.3.0) 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).

The site is flanked to the west by coastal ranges rising to more than 1400m and to the east by the Coral Sea. The red clay loam podzolic soils are of metamorphic origin and have good drainage characteristics. The metamorphic rocks grade into granite boulders along Thompson Creek which runs along the northern boundary of the site. The crane site itself is gently sloping but the fetch area makes the site one of very complex terrain. The forest is classed as complex mesophyll vine forest (type 1a) and has an average canopy height of 25m. The dominant canopy trees belong to the Apocynaceae, Arecaceae, Euphorbiaceae, Lauraceae, Meliaceae, Myristicaceae and Myrtaceae families. The forest is continuous for several kilometres around the crane except for an area 300m due east of the crane, which is regrowth forest. Annual average rainfall at the site is around 5180mm and is strongly seasonal, with 66% falling between January and April (wet season). Mean daily temperature ranges from 26.6°C in February to 21.2°C in July. <br> Tropical cyclones are a frequent occurrence in Far North Queensland. These severe tropical storm systems are natural phenomena which play a major role in determining the ecology of Queensland's tropical lowland rainforests. In March 1999 Tropical Cyclone Rona (Category 3) passed over the Cape Tribulation area causing widespread damage (gusts >170km/h). At the site several large trees fell, nearly all of the remaining trees were stripped of leaves and the lianas towers were torn to ground level. <br> The flux station was mounted at the 45m level on the tower of the Australian Canopy Crane external link. The canopy crane is a Liebherr 91 EC, freestanding construction tower crane. The crane is 48.5 metres tall with a radius of 55 metres enabling access to 1 hectare of rainforest. Fluxes of heat, water vapour and carbon dioxide were measured using the open-path eddy covariance technique. Supplementary measurements above the canopy included temperature, humidity, rainfall, total solar; these measurements have continued post the flux system decommissioning. Heat flux, soil temperature and water content (time domain reflectometry) were measured in proximity to the flux station; these measurements have continued post the flux system decommissioning. Detailed biometric measurements are made at the crane site and all trees have regular (5 yearly) dbh measurements and canopy mapping carried out. Monitoring bores (3) are located on site. Leaf litter measurements are carried out on a monthly basis. <br> For additional site information, see https://www.tern.org.au/tern-observatory/tern-ecosystem-processes/daintree-rainforest-supersite/ .<br /><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.

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 was identified as tropical pasture dominated by species <em>Chamaecrista rotundifolia</em> (Round-leaf cassia cv. Wynn), <em>Digitaria milijiana</em> (Jarra grass) and <em>Aristida sp.</em> standing at approximately 0.3m tall. The soil at the site was a mixture of red kandosol and deep sand. Elevation of the site was close to 70m and mean annual precipitation at a nearby Bureau of Meteorology site was 1250mm. Maximum temperatures ranged from 37.5°C (in October) to 31.2°C (in June), while minimum temperatures ranged from 12.6°C (in July) to 23.8°C (in January). Maximum temperatures varied on a seasonal basis between 6.3°C while minimum temperatures varied by 11.2°C. <br /> <br /> The instrument mast was 15 meters tall. Heat, water vapour and carbon dioxide measurements were 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. <br />Ancillary measurements taken at the site included 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. <br /> The site was destroyed by fire in September 2013. <br />

The island weeds database contains weed records for 697 islands and 1995 plant species. Data sources cited span between 1913 and 2014. To compound the value of the database, original species identifications were verified by Parks and Wildlife botanists and species names were updated to current taxonomy using the WA census data housed within MAX Version 3.0 (Woodman and Gioia 2016). We do not present any interpretation of the data with this data submission. GPS coordinates for weeds were largely unavailable, so most coordinates provided within the database are island centroids.
