Brief description
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.
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.
Lineage
Data collected using standard eddy covariance and meteorological instrumentation on a 4m tower at the Clareview site. The data were quality controlled by the site Principle Investigator. Gap filling and partitioning has been done using the ONEFlux software package, see Pastorello et al. 2020, which is available at https://github.com/fluxnet/ONEFlux.Data Creation
Data is measured using standard micro-meteorological instrumentation on a flux tower.
Data is recorded on a data logger and is collected by the site PI.
Data quality control and post-processing has been done by the site PI.
Filtering for low-ustar conditions, gap filling and partitioning of NEE into GPP and ER are done using ONEFlux.

Clareview is a commercial farm set up to compare “regenerative” and “conventional” dairy practices. To do that, the farm operates two cow herds separately, and about half of the paddocks are assigned to each herd and managed accordingly. The tower was set up at the boundary of both paddocks, primarily to obtain CO2 and N2O fluxes from both paddocks by a split-footprint approach.
Data Quality Assessment Scope
local :
dataset
<br>The data have been quality controlled by the site PI using standard micro-meteorological methods. </br>
<br>If the data quality is poor, the meteorological data is filled from ERA5 reanalysis data and fluxes are filled using the Marginal Distribution Sampling method. Filled data can be identified by the Quality Controls flags in the dataset. </br>
<br>The ONEFlux software used to gap fill and partition this data set also applies a Median Absolute Deviation (MAD) filter to the carbon dioxide, latent heat and sensible heat before the gap filling step.</br>
