Yanco Flux Data Release 2024_v2

<br>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).</br> <br>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.</br> <br>The flux station tower extends to 20&nbsp;m, however flux measurements are recorded from slightly lower than this. Mean annual precipitation from the nearby Bureau of Meteorology is 465&nbsp;mm. Maximum temperatures ranged from 16.6&nbsp;°C (in July) to 37.4&nbsp;°C (in January), while minimum temperatures ranged from 11.8&nbsp;°C (in July) to 29.0&nbsp;°C (in January). Maximum temperatures varied on a seasonal basis by approximately 20.8&nbsp;°C and minimum temperatures by 17.2&nbsp;°C.</br> <br>The site is within a wider research area (60 x 60&nbsp;km) that supports a network of flux stations, which have been in operation since late 2001.</br>

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通量塔观测数据。数据按照Isaac等人（2017）所述流程，使用PyFluxPro（v3.4.17）进行处理。PyFluxPro可生成最终的间隙填充数据集，将生态系统碳交换量（Net Ecosystem Exchange, NEE）划分为总初级生产力（Gross Primary Productivity, GPP）与生态系统呼吸（Ecosystem Respiration, ER）。<br>该区域地形平坦，主要土壤类型包括砂壤土、分散黏壤土、红棕壤土、过渡型红棕壤土、黏土层上覆砂层及深层砂层；全区分布有河谷、层状土壤与沉积物质。<br>通量观测塔高度达20米，但通量观测数据的采集高度略低于塔高。邻近气象局（Bureau of Meteorology）统计的年平均降水量为465毫米。最高气温介于16.6°C（7月）至37.4°C（1月）之间，最低气温介于11.8°C（7月）至29.0°C（1月）之间；最高气温的季节波动幅度约为20.8°C，最低气温的季节波动幅度约为17.2°C。<br>该观测站点位于总面积60×60千米的更大研究区域内，该区域布设了一套通量站网络，自2001年末起持续运行至今。
