Ridgefield 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).

The flux station is located within an area of dryland agriculture. The surrounding area is dominated by broadacre farming practices. The vegetation cover is predominantly pasture. Elevation of the site is close to 330 m. Climate information comes from the nearby Pingelly BoM AWS station 010626 (1991 to 2016) and shows mean annual precipitation is approximately 445 mm with highest rainfall in June and July of 81 mm each month. Maximumum and minuimum annual rainfall is 775 and 217 mm, respectively. Maximum temperatures range from 31.9 °C (in Jan) to 15.4 °C (in July), while minimum temperatures range from 5.5 °C (in July) to 16.0 °C (in Feb).

本数据集包含利用涡度相关法（eddy covariance）开展的地表与大气边界层间能量与物质交换通量塔观测数据。数据采用PyFluxPro（v3.4.18）进行处理，处理流程参照Isaac等人（2017）的研究方案。PyFluxPro可生成经间隙填充的最终数据集，并将净生态系统交换（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）。

该通量观测站位于旱地农业区内，周边区域以大面积大田耕作（broadacre farming）模式为主，地表植被以牧场为主。观测站海拔接近330米。气候数据来源于附近的澳大利亚气象局（Bureau of Meteorology, BoM）自动气象站（Automatic Weather Station, AWS）010626号站（Pingelly），观测时段为1991年至2016年。该站数据显示，研究区年平均降水量约为445毫米，6月和7月为降雨高峰期，单月降雨量达81毫米；年最大降雨量与最小降雨量分别为775毫米和217毫米。年最高气温区间为1月的31.9℃至7月的15.4℃，年最低气温区间为7月的5.5℃至2月的16.0℃。
