Longreach Mitchell Grass Rangeland Flux Data Release 2025_v2

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 (v3.4.21) 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 flux station is located at Rosebank Station, approximately 11 km south-east of Longreach in Queensland. The site is arid tussock grassland with a variety of grass species including Astrebla lappacea and Astrebla squarrosa over black vertosol soil that supports sheep and beef cattle grazing. Traditional owners at this site are the Iningai people.

本数据集包含利用涡度协方差（eddy covariance）技术获取的地表与大气边界层间能量与物质交换的通量塔观测数据。数据参照Isaac等人（2017年）所述方法，使用PyFluxPro（v3.4.21）完成处理。PyFluxPro可生成最终的间隙填充数据集，将净生态系统交换（Net Ecosystem Exchange, NEE）划分为总初级生产力（Gross Primary Productivity, GPP）与生态系统呼吸（Ecosystem Respiration, ER）。该通量站坐落于昆士兰州朗里奇（Longreach）东南约11公里处的罗斯班克牧场（Rosebank Station）。本站点为干旱丛状草原，土壤为黑变性土，生长有含卷颖三芒草（Astrebla lappacea）与硬秆三芒草（Astrebla squarrosa）在内的多种草本植物，可供绵羊与肉牛放牧。该站点的传统原住民土地所有者为伊宁盖（Iningai）族群。
