Otway 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.</p> <p>The Otway flux station was established in February 2007 on private land at Nirranda South in south west Victoria, Australia (GPS coordinates: -38.5323, 142.8168; elevation: 54m). It was managed by CSIRO Marine and Atmospheric Research staff as part of the Cooperative Research Centre for Greenhouse Gas Technologies.<br />The pasture was grazed by dairy cattle with average grass height of 0.1m.<br />Annual average rainfall at the site was around 800mm and was only moderately seasonal. Mean daily temperature ranged from 25&deg;C in February to 12&deg;C in July.<br />The flux station was situated on a 10m tower. Fluxes of heat, water vapour and carbon dioxide were measured using the open-path eddy covariance technique. Supplementary measurements included temperature, humidity, rainfall, total solar, photosynthetically active radiation (PAR) and net radiation. Soil temperature and heat flux were also measured.</p>
