Clareview 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 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.</p> <p>Clareview Farm is a commercial dairy farm where half of the cows and paddocks are managed with "conventional" (New Zealand typical) and the other half with "regenerative" practice (much lower fertiliser input, highly diverse pastures and longer grazing rotations). The flux station is at the boundary of a regenerative and a conventional paddock, to sample CO2 and N2O exchange from both, using a split-footprint approach. The CO2 exchange (NEE) is combined with biomass removal during grazing periods and excreta returns to calculate the net ecosystem carbon balance (NECB) for each paddock. NECB and N2O emissions are considered together to assess which practice has the more favourable greenhouse gas budget.</p>
