Lauder 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>The Lauder Eddy Covariance system (ECS) is in a paddock (6.28 h) of a local farm, adjacent to the NIWA Lauder atmospheric research station, 169&deg;40'49.143" E 45&deg;2'16.004" S, 390 m above mean sea level. Lauder is in the Manuherika Valley, Central Otago, New Zealand, approximately 37 km north of Alexandra. <br />The Eddy Covariance CO₂ flux measurements made at Lauder were specifically instigated for the Endeavour funded Carbonwatch NZ project. Grasslands are likely to be associated with potentially significant carbon sources and sinks, which may be manageable. Currently, New Zealand&rsquo;s National Inventory Report (NIR) assumes established grasslands have zero net flux. Measurements are vital to estimate realistic fluxes.</p>
