Daly Uncleared Flux Data Collection

This dataset consists of measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer in woodland savanna using eddy covariance techniques.<br /><br /> The site is woodland savanna with an overstory co-dominated by tree species <em>E. tetrodonta</em>, <em>C. latifolia</em>, <em>Terminalia grandiflora</em>, <em>Sorghum sp.</em> and <em>Heteropogon triticeus</em>. Average canopy height measures 16.4 m. <br />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. <br /><br />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.<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. <br /><br />This data is also available at http://data.ozflux.org.au .

Purpose
The purpose of the Daly Uncleared Flux station is to: <br /> Provide information as part of a larger network of flux stations established along the North Australian Tropical Transect (NATT) gradient, which extends ~1000km south from Darwin 12.5°S. <br /> Examine spatial patterns and processes of land-surface-atmosphere exchanges (radiation, heat, moisture, CO2 and other trace gasses) across scales from leaf to landscape scales within Australian savannas. <br /> Determine the climate and ecosystem characteristics (physical structure, species composition, physiological function) that drive spatial and temporal variations of carbon, water and energy fluxes from north Australian savanna. <br /> Quantify fluxes over woodland savanna. <br /> Provide longer term measurements for future projects.

Data quality info

Hierarchy level
Dataset
Other
If the data quality is poor, the data is filled from alternative sources. Filled data can be identified by the Quality Controls flags in the dataset. Quality control checks include (i) range checks for plausible limits, (ii) spike detection, (iii) dependency on other variables and (iv) manual rejection of date ranges. Specific checks applied to the sonic and IRGA data include rejection of points based on the sonic and IRGA diagnostic values and on either automatic gain control (AGC) or CO2 and H2O signal strength, depending upon the configuration of the IRGA. For more details, refer to Isaac et al (2017) in the Publications section, https://doi.org/10.5194/bg-14-2903-2017. For further information about the software (PyFluxPro) used to process and quality control the flux data, see https://github.com/OzFlux/PyFluxPro/wiki .

Resource lineage

Statement
All flux raw data is subject to the quality control process OzFlux QA/QC to generate data from L1 to L6. Levels 3 to 6 are available for re-use. Datasets contain Quality Controls flags which will indicate when data quality is poor and has been filled from alternative sources. For more details, refer to Isaac et al (2017) in the Publications section, https://doi.org/10.5194/bg-14-2903-2017 .
