Collie FLUXNET Release 2026_r1

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 as described by Isaac et al. (2017) for the quality control and post-processing steps. The final, gap-filled product containing Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER) has been produced using the ONEFlux software as described in Pastorello et al. (2020). This data set has been produced as part of the FLUXNET Shuttle project.The Collie flux station was located approximately 10km southeast of Collie, near Perth, Western Australia (GPS coordinates: -33.420, 116.237; elevation 384m).It was established in August 2017, stopped measuring in November 2019, and the flux instrumentation was managed by The University of Western Australia.The flux tower site was located within an area of wandoo woodland. Elevation of the site was close to 384 m. Climate information came from the nearby Collie BoM AWS station 009628 (1899 to present) and shows mean annual precipitation was approximately 933 mm with highest rainfall in June and July of ~176 mm each month.Maximum temperatures range from 30.5°C (in Jan) to 15.5°C (in July), while minimum temperatures range from 4.2°C (in July) to 13.2 °C (in Jan).The instrument mast was 35m tall. Heat, water vapour, and carbon dioxide measurements were taken using the open-path eddy flux technique. Temperature, humidity, wind speed, wind direction, soil heat fluxes, soil temperature, and soil moisture content were also collected.本数据集包含采用涡度协方差（eddy covariance）技术获取的地表与大气边界层间能量与物质交换通量塔观测数据。数据处理采用PyFluxPro软件完成，质控与后处理流程参照Isaac等人（2017）的研究方法。最终的间隙填充数据集包含生态系统净交换（Net Ecosystem Exchange, NEE），并将其划分为总初级生产力（Gross Primary Productivity, GPP）与生态系统呼吸（Ecosystem Respiration, ER），该数据集通过ONEFlux软件生成，流程参照Pastorello等人（2020）的研究。本数据集作为FLUXNET Shuttle项目的一部分完成构建。 Collie通量站位于澳大利亚西澳州珀斯附近的Collie东南约10公里处（GPS坐标：-33.420, 116.237；海拔384米）。该站点于2017年8月建成，2019年11月停止观测，通量观测仪器由西澳大学（The University of Western Australia）管理。通量塔站点位于万杜桉（wandoo）林地范围内，站点海拔接近384米。 气候数据来自附近的Collie澳大利亚气象局（Bureau of Meteorology, BoM）自动气象站009628，观测时间跨度为1899年至今。数据显示该区域年平均降水量约为933毫米，6月和7月为降雨高峰期，单月降雨量约176毫米。最高气温范围为30.5℃（1月）至15.5℃（7月），最低气温范围为4.2℃（7月）至13.2℃（1月）。观测桅杆高度为35米，热通量、水汽与二氧化碳通量采用开路式涡度通量（open-path eddy flux）技术进行观测。此外还同步采集了气温、相对湿度、风速、风向、土壤热通量、土壤温度以及土壤含水量等观测数据。
