Collie FLUXNET Release 2026_r1

<p>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.<br />The Collie flux station was located approximately 10km southeast of Collie, near Perth, Western Australia (GPS coordinates: -33.420, 116.237; elevation 384m).<br />It was established in August 2017, stopped measuring in November 2019, and the flux instrumentation was managed by The University of Western Australia.<br />The flux tower site was located within an area of wandoo woodland. Elevation of the site was close to 384 m. Climate information came from the nearby Collie BoM AWS station 009628 (1899 to present) and shows mean annual precipitation was approximately 933 mm with highest rainfall in June and July of ~176 mm each month.<br />Maximum temperatures range from 30.5&deg;C (in Jan) to 15.5&deg;C (in July), while minimum temperatures range from 4.2&deg;C (in July) to 13.2 &deg;C (in Jan).<br />The instrument mast was 35m tall. Heat, water vapour, and carbon dioxide measurements were taken using the open-path eddy flux technique. Temperature, humidity, wind speed, wind direction, soil heat fluxes, soil temperature, and soil moisture content were also collected.</p>
