Whroo Flux Data Release 2022_v1

This data release consists of flux tower measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer in semi-arid eucalypt woodland using eddy covariance techniques. It been processed using PyFluxPro (v3.3.3) as described in Isaac et al. (2017), https://doi.org/10.5194/bg-14-2903-2017. PyFluxPro takes data recorded at the flux tower and process this data to a final, gap-filled product with Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER). For more information about the processing levels, see https://github.com/OzFlux/PyFluxPro/wiki.
The site was classified as box woodland, dominated by two main Eucalypt species:Eucalyptus microcarpa (Grey Box) and Eucalyptus leucoxylon (Yellow Gum). Elevation of the site is close to 165 m and mean annual precipitation from a nearby Bureau of Meteorology site measured 558 mm. Maximum temperatures ranged from 29.8°C (in January) to 12.6°C (in July), while minimum temperatures ranged from 14.2°C (in February) to 3.2°C (in July). Maximum temperatures varied on a seasonal basis by approximately 17.2°C and minimum temperatures by 11.0°C.The instrument mast is 36m tall. Heat, water vapour and carbon dioxide measurements are taken using the open-path eddy flux technique. Temperature, humidity, wind speed, wind direction, rainfall, incoming and reflected shortwave radiation and net radiation were measured above the canopy. Soil heat fluxes were measured and soil moisture content was gathered using time domain reflectometry.

本数据集包含采用涡度协方差技术（eddy covariance techniques）获取的半干旱桉树林地地表与大气边界层间能量与物质交换通量塔观测数据。本数据集采用PyFluxPro（v3.3.3）进行处理，处理方法参照Isaac等人（2017）的研究成果，详见https://doi.org/10.5194/bg-14-2903-2017。PyFluxPro可将通量塔记录的原始数据处理为最终的间隙填充数据集，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）。如需了解更多关于数据处理级别的相关信息，请访问https://github.com/OzFlux/PyFluxPro/wiki。
该站点被归类为箱状林地，优势树种为两种桉属植物：微果桉（Eucalyptus microcarpa，灰盒桉）与白桉（Eucalyptus leucoxylon，黄胶桉）。该站点海拔接近165米，邻近的澳大利亚气象局（Bureau of Meteorology）观测站点测得的年平均降水量为558毫米。最高气温范围为29.8℃（1月）至12.6℃（7月），最低气温范围为14.2℃（2月）至3.2℃（7月）。最高气温的季节波动幅度约为17.2℃，最低气温的季节波动幅度约为11.0℃。观测塔塔高36米，采用开放式路径涡度通量技术测量热量、水汽与二氧化碳通量。冠层上方监测了气温、相对湿度、风速、风向、降雨量、入射与反射短波辐射以及净辐射。采用时域反射法（time domain reflectometry）测量土壤热通量并采集土壤含水率。
