Warra FLUXNET Release 2026_r1 

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). This data set has been produced as part of the FLUXNET Shuttle project. The Warra flux site is located in the Warra LTER area in south-western Tasmania, between the Huon and Weld Rivers. It includes both protected wilderness and State forest used for timber production since the 1970s. The site sits at 100 m elevation near the Huon River and has a temperate climate with mild summers, cool winters, and about 1700 mm of annual rainfall.
The area is dominated by tall Eucalyptus obliqua forests with a rainforest understorey and dense tree ferns. An 80 m tower measures carbon dioxide, heat, and water vapour exchange, along with weather and soil conditions such as moisture and temperature. 

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 Warra flux site is: - to study the ecophysiological processes and rates of C accumulation and decomposition in a mixed-aged, tall, wet Eucalyptus obliqua forest originating from past natual wildfires. - to measure the exchanges of carbon dioxide, water vapour and energy between the forest and the atmosphere using micrometeorological techniques. - to link ecophysiological processes and rates of C accumulations and decomposition with the biota. - to utilize the measurements in combination with remote sensing data and land surface models to upscale estimate the net exchanges of carbon and water at regional scale. 

Data collected using standard eddy covariance and meteorological instrumentation on a 80m tower at the Warra 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.
