This dataset consists of measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer in pasture using eddy covariance techniques.
The Samford flux station is situated on an improved (Paspalum dilatum) pasture in the humid subtropical climatic region of coastal south-east Queensland. Located only 20km from the centre of Brisbane city, Samford Valley provides an ideal case study to examine the impact of urbanisation and land use change on ecosystem processes. The valley covers an area of some 82km2 and is drained in the southern regions by the Samford creek, which extends some 13km to Samford Village and into the South Pine River. The Samford Valley is historically a rural area experiencing intense urbanisation, with the population increasing almost 50% in the 10 years to 2006 (Morton Bay Regional Council, 2011). Within the Samford valley study region, the Samford Ecological Research Facility (SERF) not only represents a microcosm of current and historical land uses in the valley, but provides a unique opportunity to intensively study various aspects of ecosystem health in a secure, integrated and long term research capacity. Mean annual minimum and maximum temperatures at a nearby Bureau of Meteorology site are 13.1°C and 25.6°C respectively while average rainfall is 1102mm.

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 site was established around the Samford Ecological Research Facility and managed by the Queensland University of Technology (QUT). The Samford site is affiliated to TERN and flux data collection is jointly funded by TERN and QUT.
Purpose
The purpose of the Samford site is to:
Examine the influence of land-use change and intensification associated with peri-urban environments on soil, plant, animal and atmosphere interactions.
Measure the exchange of carbon dioxide, water vapour and energy between the soil/pasture and the atmosphere of an improved pasture in response to increasing harvest intervals.
Use micrometeorological techniques in conjunction with automatic GHG static closed chambers (CO2, N2O, CH4), soil moisture probe transects, stream water quality and terrestrial biomass measurements to close the carbon, water and nitrogen budgets of the improved pasture.
Develop a full global warming potential analysis from this data for this land use.
Examine the suitability of micrometeorological techniques in complex terrain in a sub-tropical environment
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.
