Wedgetail Flux Data 2025_v2 

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 as described by Isaac et al. (2017) for the quality control and post-processing steps. The final, gap-filled product containing Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER) has been produced using the ONEFlux software as described in Pastorello et al. (2020). The Wedge Tail flux tower (42°05'29"S, 147°04'46"E) is located on the traditional lands of the Lairmairrener people within the Silver Plains Reserve, a property managed by the Tasmanian Land Conservancy.
Installed on 29 July 2024 by the University of Tasmania, the Wedge Tail flux tower is situated approximately 550 meters from the adjacent Silver Plains Flux Tower. 
The surrounding landscape is a gently south-southwest sloping, species-rich sedgeland and grassland, with a history of grazing. Positioned at an elevation of 860 meters, the site receives an average annual precipitation of approximately 900 mm. The soil at the site is organosol on a Jurassic dolerite geology. Average seasonal temperatures range from 16°C in summer to 6°C in winter. 

We at TERN acknowledge the Traditional Owners and Custodians throughout Australia, New Zealand and all nations. We honour their profound connections to land, water, biodiversity and culture and pay our respects to their Elders past, present and emerging. 

The purpose of the Wedgetail flux tower is to: - Monitor exchanges of carbon dioxide, water vapour and energy in a high-altitude grassy peatland ecosystem on the Tasmanian Central Plateau.
- Quantify the carbon balance of the ecosystem, along with the key components of net ecosystem exchange, gross primary productivity and ecosystem respiration.
- Identify key environmental and climatic drivers of carbon, water and energy fluxes.
- Complement manual chamber measurements of net ecosystem CO₂ exchange in an adjacent climate change experiment.
- Utilize measurements alongside manual chamber measurements and ancillary environmental variables to model ecosystem carbon dynamics under a future climate. Furthermore Wedgetail serves as a control site for the Silver Plains flux tower (AU-Sil), situated ~550m east of Wedgetail, which will undergo hydrological remediation from 2027-2028. 

Data collected using standard eddy covariance and meteorological instrumentation on a 2.6m tower at the Wedgetail site. The data were quality controlled using the PyFluxPro software package, see Isaac et al. (2017), which is available at https://github.com/OzFlux/PyFluxPro. Gap filling and partitioning has been done using the ONEFlux software package, see Pastorello et al. 2020, which is available at https://github.com/fluxnet/ONEFlux.
