Riggs Creek Flux Data Release 2023_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 (v3.5.0) 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 site 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 152 m and mean annual precipitation at a nearby Bureau of Meteorology site measures 650 mm. Maximum temperatures range from 12.3 °C (in July) to 29.7 °C (in February), while minimum temperatures range from 10.4 °C (in July) to 26.8 °C (in February).

The instrument mast is 4 m tall. Heat, water vapour and carbon dioxide measurements are taken using the open-path eddy flux technique. Temperature, humidity, wind speed, wind direction, rainfall and net radiation are measured. Soil heat fluxes are measured and soil moisture content is gathered using time domain reflectometry.

本数据集包含采用涡度协方差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。数据处理采用PyFluxPro（v3.5.0）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）。
该通量站位于旱地农业区内，周边区域以连片大田农业模式为主，植被覆盖以牧草地为主。站点海拔接近152米，邻近的气象局（Bureau of Meteorology）站点记录的年平均降水量为650毫米。月最高气温介于12.3℃（7月）至29.7℃（2月）之间，月最低气温则介于10.4℃（7月）至26.8℃（2月）之间。
观测塔高4米。采用开放式涡度通量技术获取热量、水汽与二氧化碳的观测数据。同步观测的气象要素包括气温、湿度、风速、风向、降雨量与净辐射。土壤热通量及土壤含水率则通过时域反射仪（time domain reflectometry）采集。
