Dry River Flux Data Collection
This dataset consists of measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer in open forest savanna using eddy covariance techniques.<br /><br /> The site is classified as open forest savanna. The overstory is co-dominated by tree species <em>E. tetrodonta</em>, <em>E. dichromophloia</em>, <em>C. terminalis</em>, <em>Sorghum intrans</em>, <em>S. plumosum</em>, <em>Themeda triandra</em> and <em>Chrysopogon fallax</em>, with canopy height averaging 12.3m. Elevation of the site is close to 175m and mean annual precipitation from a nearby Bureau of Meteorology site measures 895.3mm. Maximum temperatures range from 29.1°C (in June) to 37.6°C (in July), while minimum temperatures range from 14.6°C (in July) to 24.8°C (in November). Maximum temperatures vary seasonally by 8.5°C and minimum by 10.2°C. <br /><br /> The instrument mast is 15 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. Soil heat fluxes are measured and soil moisture content is gathered using time domain reflectometry. <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 Dry River 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 ~1000 km 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 /> Determine if fluxes of carbon, water vapour and heat over the various ecosystems as derived from the various measurement techniques can be to form a comprehensive and consistent estimate of the regional fluxes and budgets across the landscape.

Data quality info

- 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.
