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 (v3.4.17) as described by Isaac et al. (2017). PyFluxPro produces a final, gap-filled product with Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER).
The Yarramundi Irrigated site is an improved, managed pasture on the Western Sydney University Hawkesbury campus. Original woodland vegetation was cleared prior to 1950. A mixture of native and exotic grasses and forbs dominate the site, which is used by cattle in an intensively managed grazing operation. The flux tower was established in October of 2019 and is managed by the Hawkesbury Institute for the Environment, with partial support from TERN and WSU Office of Estate and Commercial (Farm Production Unit).
The climate is warm-temperate, with annual rainfall averaging 728 mm, mean maximum temperature in January of 30.4°C and mean minimum temperature in July of 3.6°C (BOM station 067105). The elevation of the site is about 20 m asl and the topography is flat. The soil is sandy loam in texture, organic carbon content is <1%.
