    This dataset consists of measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer in southeast of Emerald, Queensland, using eddy covariance techniques. <br /> <br /> The Arcturus greenhouse gas (GHG) monitoring station was established in July 2010, 48 km southeast of Emerald, Queensland, with flux tower measurements starting in June 2011 until early 2014. The station was part of a collaborative project between Geoscience Australia (GA) and CSIRO Marine and Atmospheric Research (CMAR). Elevation of the site was approximately 170m asl and mean annual precipitation was 572mm. The tower bordered 2 land use types split N-S: To the west lightly forested tussock grasslands; To the east crop lands, cycling through fallow periods.The instruments were installed on a square lattice tower with an adjustable pulley lever system to raise and lower the instrument arm. The tower was 5.6m tall with the instrument mast extending a further 1.1m above, totalling a height of 6.7m. Fluxes of heat, water vapour, methane and carbon dioxide were measured using the open-path eddy flux technique. Supplementary measurements above the canopy included temperature, humidity, windspeed, wind direction, rainfall, and the 4 components of net radiation. Soil heat flux, soil moisture and soil temperature measurements were also collected. <br /> For additional site information, see http://www.ozflux.org.au/monitoringsites/arcturus/index.html.<br /><br /> This data is also available at http://data.ozflux.org.au .
