Wombat State Forest Flux Data Release 2021_v1
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). 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 Wombat State Forest site is a secondary re-growth forest that was last harvested in 1980. Dominant tree species are <em>Eucalyptus obliqua</em> (messmate stringybark), <em>Eucalyptus radiata</em> (narrow leaf peppermint) and <em>Eucalyptus rubida</em> (candlebark) with an average canopy height of 25m. The understorey consists mainly of patchy grasses and the soil is a silty-clay overlying clay. The forest is managed by the Department of Sustainability and Environment and management includes selective harvesting and prescribed burning regimes. The climate of the study area is classified as cool-temperate to Mediterranean zone with cold and wet winters (May-Aug) and warm and dry summers (Dec-Feb) with a temperature range: 1-30 °C and mean annual air temperature (2001-2012): 12.1°C. Annual rainfall is approximately 871 mm (142 year long-term average). Coherent automated measurements of soil greenhouse gas fluxes (CO2, CH4 and N2O) were collected using a trailer-mounted mobile laboratory – Fourier transform infra-red (FTIR) spectrometer from 2010 to 2016. Measurement height was 30m but increased to 33m from January 2017<br /><br />

- Purpose
- The Wombat Forest research site facilitates the investigation of complex ecosystem processes of the carbon, water and nutrient cycle in a dry-sclerophyll forest ecosystem that is typical for many forests in Australia. This research will help to assess the impact of future environmental change on forest ecosystems in Australia. The Wombat Forest research site will: <br /> Quantify the carbon sink/source strength of a dry sclerophyll forest and identify the contribution of such forests to the Australia's National Carbon Inventory <br /> Quantify the emission and/or uptake of non-CO2 greenhouse gases, such as nitrous oxide and methane of the forest <br /> Assess the role of climate variability and drought on ecosystem processes <br /> Assess the impact of disturbances (such as fire) on ecosystem processes <br /> Provide a database of microclimate and ecological parameters for use in carbon and water modelling 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.
