The Ti Tree East site was established in July 2012 and is managed by the University of Technology Sydney. Pine Hill Station is a functioning cattle station that has been in operation for longer than 50 years. However, the east side has not been stocked in over three years. The site is a mosaic of the primary semi-arid biomes of central Australia: grassy mulga woodland and Corymbia/Triodia savanna.The woodland is characterised by a mulga (Acacia aneura) canopy, which is 4.85 m tall on average. The soil is red sand overlying an 8 m deep water table. Elevation of the site is 553 m above sea level, and the terrain is flat. Mean annual precipitation at the nearby (30 km to the south) Bureau of Meteorology station is 305.9 mm but ranges between 100 mm in 2009 to 750 mm in 2010. Predominant wind directions are from the southeast and east. The instrument mast is 10 m tall. Fluxes of heat, water vapour and carbon are measured using the open-path eddy covariance technique at 9.81m. Supplementary measurements above the canopy include temperature and humidity (9.81 m), windspeed and wind direction (8.28 m), downwelling and upwelling shortwave and longwave radiation (9.9 m). Precipitation is monitored in the savanna (2.5m). Supplementary measurements within and below the canopy include barometric pressure (2 m). Below ground soil measurements are made beneath Triodia, mulga and grassy understorey and include ground heat flux (0.08 m), soil temperature (0.02 m – 0.06 m) and soil moisture (0 – 0.1m, 0.1 – 0.3m, 0.6 – 0.8m and 1.0 – 1.2m). For additional site information, see http://ozflux.org.au/siteOfTheMonth/2020-09Alice-and-TiTree/2020-09Alice-and-TiTree.html . This data is also available at http://data.ozflux.org.au .All flux raw data is subject to the quality control process OzFlux QA/QC to generate data from L1 to L6. Levels 3 to 6 are available for re-use. Datasets contain Quality Controls flags which will indicate when data quality is poor and has been filled from alternative sources.

Brief description

The site is a mosaic of the primary semi-arid biomes of central Australia: grassy mulga woodland and Corymbia/Triodia savanna.The woodland is characterised by a mulga (Acacia aneura) canopy, which is 4.85 m tall on average.

Lineage

All flux raw data is subject to the quality control process OzFlux QA/QC to generate data from L1 to L6. Levels 3 to 6 are available for re-use. Datasets contain Quality Controls flags which will indicate when data quality is poor and has been filled from alternative sources.

Notes

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.
The Ti Tree East flux station is managed by the University of Technology Sydney. It is established in conjunction with the TERN Alice Springs Supersite, the Alice Springs OzFlux site and the Woodforde River NGCRT Superscience Site.
Purpose
The purpose of the Ti Tree East flux station is to :
measure the exchanges of carbon dioxide, water vapour and energy in a semi-arid ecosystem with potential access to groundwater
identify flux footprints associated with contributions by mulga versus Corymbia savannas
compare water use efficiency, GPP and ecosystem respiration between adjacent semi-arid ecosystems (Alice Springs mulga)
identify relationships between groundwater, soil moisture, rainfall and evapotranspiration
identify phenological trends and to relate phenology to flux footprints and remote sensing of water and carbon fluxes.
Data Quality Information

Data Quality Assessment Scope
local : dataset
If the data quality is poor, the data is filled from alternative sources. Filled data can be identified by the Quality Controls flags in the dataset. Quality control checks include (i) range checks for plausible limits, (ii) spike detection, (iii) dependency on other variables and (iv) manual rejection of date ranges. Specific checks applied to the sonic and IRGA data include 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. For more details, refer to Isaac et al (2017) in the Publications section, https://doi.org/10.5194/bg-14-2903-2017. <br> For further information about the software (PyFluxPro) used to process and quality control the flux data, see https://github.com/OzFlux/PyFluxPro/wiki.
