    This dataset includes volumetric soil water content measured across soil pits in the lowland rainforest of Cape Tribulation. Data were acquired using time-domain reflectometry (TDR) probes recording at soil surface (10 cm) and at depths (50, 100 and 150 cm) at 4 control points - PB1 and PB8 are in the SW quadrant of the crane plot, PB2 and PB5 are in the NW quadrant of the crane plot.

    This dataset consists of measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer in tropical pasture using eddy covariance techniques.<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 /><br />This data is also available at http://data.ozflux.org.au .

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 Cumberland Plain flux station is located in a dry sclerophyll forest. The Cumberland Plain Woodland is now an endangered ecological community that encompasses distinct groupings of plants growing on clayey soils. The canopy is dominated by <em>Eucalyptus moluccana</em> and <em>Eucalyptus fibrosa</em>, which host an expanding population of mistletoe. Average canopy height is 23&nbsp;m, the elevation of the site is 20&nbsp;m and mean annual precipitation is 800&nbsp;mm. Fluxes of water vapour, carbon dioxide and heat are quantified with the open-path eddy flux technique from a 30&nbsp;m tall mast. Additional measurements above the canopy include temperature, humidity, wind speed and direction, rainfall, incoming and reflected shortwave and longwave radiation and net, diffuse and direct radiation and the photochemical reflectance index. In addition, profiles of humidity and CO<sub>2</sub> are measured at eight levels within the canopy, as well as measurements of soil moisture content, soil heat fluxes, soil temperature, and 10&nbsp;hr fuel moisture dynamics. In addition, regular monitoring of understory species abundance, mistletoe infection, leaf area index and litterfall are also performed.

The site is about 1&nbsp;km east of the Cumberland Plain Woodland flux tower. The climate is warm-temperate, with annual rainfall averaging 728&nbsp;mm, mean maximum temperature in January of 30.4&deg;C and mean minimum temperature in July of 3.6&deg;C (BOM station 067105). The elevation of the site is about 20&nbsp;m asl and the topography is flat. The soil is sandy loam in texture, organic carbon content is <1% nutrient availability is very low in the top 10&nbsp;cm; iron concretions below 50&nbsp;cm indicate poor drainage at times. The vegetation canopy is less than 1&nbsp;m tall, and the plant community is dominated by exotic herbaceous perennials, including <em>Conyza sumatrensis</em>, <em>Setaria parviflora</em>, <em>Cynodon dactylon</em>, <em>Commelina cyanea</em>, <em>Senecio madagascariensis</em>, and <em>Eragrostis curvula</em>. <br /> <br> Fluxes of water vapour, carbon dioxide and heat are quantified with the open-path eddy flux technique from a 2.5&nbsp;m tall mast. Additional measurements above the canopy include temperature, humidity, rainfall and net radiation, and photographs are taken several times per day to track canopy greenness.</br>
