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.
There were two micrometeorological EC flux towers, at ca. 300 m distance from each other. One of them was in an irrigated, fertilised, rotationally grazed paddock (labelled "IFR" in file names), Fluxnet site name NZ-BFm. Measurements at this site ceased on 15 July 2015. Three site-years of data are available, with the last 33 days of the third year completely gap-filled.
The Beacon Farm flux site in Mid-Canterbury, New Zealand (204 m elevation) receives about 900 mm of annual rainfall and has a mean temperature of 10.9°C. Originally a deer farm, it was converted to intensive dairy farming in 2008/09, supporting around 850 cows with rotational grazing.

Lineage

Data collected using standard eddy covariance and meteorological instrumentation on a 2m tower at the Beacon Farm Managed 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.

Progress Code: completed
Maintenance and Update Frequency: annually

Credit
We at TERN acknowledge the Traditional Owners and Custodians throughout Australia, New Zealand and all nations. We honour their profound connections to land, water, biodiversity and culture and pay our respects to their Elders past, present and emerging.
Purpose

- to study the impact of the conversion of dry-land grazing to irrigated dairy farming on net annual greenhouse gas (carbon dioxide, methane and nitrous oxide) emissions at paddock scales
- to study the effects of conversion of dry-land to irrigated dairy farming on soil carbon storage
- to investigate the environmental drivers of greenhouse gas emissions and changes in soil carbon storage
- to investigate the seasonal variation of greenhouse gas emissions and soil carbon storage
- to study the effect of land conversion on water use efficiency and nitrogen use efficiency
- to understand the impact of irrigation and fertiliser application on nitrate leaching.

Data Quality Information

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>

Data Quality Assessment Result
local : Quality Result
No anomalous data detected after quality control.
