Oxford 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 standard micrometeorological methods 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></br> The Oxford flux site is a 1-hectare area on the Canterbury Plains, New Zealand (235 m elevation), originally used as grazed pasture dominated by ryegrass and clover. In 1996, grazing ceased and native kānuka trees were planted, allowing natural vegetation change.<br></br> The site uses several instrument masts to measure fluxes of water vapour, heat, and carbon dioxide, along with weather and soil conditions. Additional monitoring includes vegetation properties, soil respiration, and tree growth.
