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 PyFluxPro as described by Isaac et al. (2017) 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.
The Digby Plantation flux station is located in blue gum plantation in southwestern Victoria, approximately 300 km west of Melbourne.
Digby Plantation is a E. globulus plantation site near Digby, in Southwest Victoria, Australia, within the Glenelg River Basin. The plantation was established in August 2017, with a mean tree density of approximately 1000 trees-ha-1. The depth to the water table is between 5 to 10 m. Tree height at planting was between 150 mm and 300 mm, and trees were on average 11 m tall at the end of the monitoring period (July 2021).

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
The purpose of the Digby Plantation station was to monitor the fluxes in a blue gum (Eucalyptus globulus) plantation during the first few years after its establishment. The aim was to understand how the water efficiency of the plantation changes as trees rapidly grow in the years after being planted.

Data Quality Assessment Scope
The data have been quality controlled using the PyFluxPro software. Quality control checks applied to the data include:
  • range checks for plausible limits
  • spike detection and removal
  • dependency on other variables
  • manual rejection of date ranges

Specific checks applied to the sonic and IRGA data including rejection of points based on the sonic and IRGA diagnostic values and on either automatic gain control (AGC) or CO2 and H2O signal strength, depending upon the configuration of the IRGA.

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.

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.
