Brief description
This dataset consists of measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer in dry sclerophyll forest at Cumberland Plain using eddy covariance techniques. The eddy covariance data collected in 2012-2013 includes measurements of turbulent fluxes but not the storage flux of CO2, and the micrometeorological data does not include soil moisture or soil temperature recordings. Beginning in January, 2014, a canopy profile system was implemented, allowing for calculation of the storage term, which is added to the turbulent flux of CO2 to calculate the net ecosystem exchange accurately in records from 2014 onwards. Prior to 2014, the net ecosystem exchange includes only the turbulent flux, and no soil moisture or soil temperature data are available.The Cumberland Plain flux station is located in a dry sclerophyll forest. The Cumberland Plain Woodland is now an endangered ecological community that encompasses distinct groupings of plants growing on clayey soils. The canopy is dominated by Eucalyptus moluccana and Eucalyptus fibrosa, which host an expanding population of mistletoe. Average canopy height is 23m, the elevation of the site is 20m and mean annual precipitation is 800mm.
Fluxes of water vapour, carbon dioxide and heat are quantified with the open-path eddy flux technique from a 30 m tall mast. Additional measurements above the canopy include temperature, humidity, wind speed and direction, rainfall, incoming and reflected shortwave and longwave radiation and net, diffuse and direct radiation and the photochemical reflectance index. In addition, profiles of humidity and CO2 are measured at eight levels within the canopy, as well as measurements of soil moisture content, soil heat fluxes, soil temperature, and 10-hr fuel moisture dynamics. In addition, regular monitoring of understory species abundance, mistletoe infection, leaf area index and litterfall are also performed.

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. For more details, refer to Isaac et al (2017) in the Publications section, https://doi.org/10.5194/bg-14-2903-2017 .

Purpose
The purpose of the Cumberland Plain flux station is:
to quantify the exchanges of carbon dioxide, water vapour and energy in a dry sclerophyll forest.
to characterize the functional behaviour and sensitivity of the different components contributing to the ecosystem carbon balance from sub-daily to multi-annual temporal scales and under climatic variability.
to identify the role of hydraulic limitations on constraining ecosystem productivity.
to quantify the impact of mistletoe on plant physiological processes and whole ecosystem water vapour and carbon dioxide exchange.
to validate remote sensing estimates of different radiation components to obtain accurate regional predictions of fuel moisture.
to understand how wood traits and microbial diversity interact to determine rates of wood decay.

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.
