Yanco Flux Data Release 2025_v1

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 (v3.4.18) 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). This is a topographically flat area, primarily comprised of the following soil types: sandy loams, scattered clays, red brown earths, transitional red brown earth, sands over clay and deep sands. Stream valleys and layered soil and sedimentary materials are found across the landscape. The flux station tower extends to 20 m, however flux measurements are recorded from slightly lower than this. Mean annual precipitation from the nearby Bureau of Meteorology is 465 mm. Maximum temperatures ranged from 16.6 °C (in July) to 37.4 °C (in January), while minimum temperatures ranged from 11.8 °C (in July) to 29.0 °C (in January). Maximum temperatures varied on a seasonal basis by approximately 20.8 °C and minimum temperatures by 17.2 °C. The site is within a wider research area (60 x 60 km) that supports a network of flux stations, which have been in operation since late 2001.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和物质交换的通量塔观测数据。数据处理采用PyFluxPro（v3.4.18）完成，处理流程遵循Isaac等人（2017）的研究方法。PyFluxPro可生成经间隙填充的最终数据集，将生态系统净交换量（Net Ecosystem Exchange, NEE）划分为总初级生产力（Gross Primary Productivity, GPP）与生态系统呼吸量（Ecosystem Respiration, ER）。 该区域地形平坦，主要土壤类型包括砂壤土、分散性黏土、红棕壤土、过渡型红棕壤、黏土上覆砂层及深层砂土，全域分布有河谷、层状土壤与沉积物质。 通量观测塔总高度达20米，但通量观测的实际采集高度略低于塔体高度。邻近气象局记录的年平均降水量为465毫米。最高气温介于16.6℃（7月）至37.4℃（1月）之间，最低气温介于11.8℃（7月）至29.0℃（1月）之间；最高气温的季节波动幅度约为20.8℃，最低气温的季节波动幅度约为17.2℃。 该观测点位于60km×60km的更大研究区域内，该区域布设有通量站网络，相关观测工作自2001年末起持续运行至今。
