Whroo Flux Data Release 2021_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 (v3.3.0) 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.

本数据集发布包含半干旱桉树林地中，利用涡度协方差技术（eddy covariance techniques）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。该数据集已按照Isaac等人（2017）提出的方法，使用PyFluxPro（v3.3.0）完成处理，相关文献链接为https://doi.org/10.5194/bg-14-2903-2017。PyFluxPro可对通量塔采集的原始数据进行处理，生成最终的间隙填充数据集，并将生态系统净交换（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）。若需了解更多关于处理层级的细节，请访问https://github.com/OzFlux/PyFluxPro/wiki。
该站点被归类为箱型桉树林，优势物种为两种桉树：灰盒桉（Eucalyptus microcarpa, Grey Box）与黄胶桉（Eucalyptus leucoxylon, Yellow Gum）。该站点海拔接近165米，附近澳大利亚气象局（Bureau of Meteorology）站点测得的年平均降水量为558毫米。最高气温介于29.8℃（1月）至12.6℃（7月）之间，最低气温则介于14.2℃（2月）至3.2℃（7月）之间。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。热通量、水汽通量与二氧化碳通量采用开路涡度通量技术（open-path eddy flux technique）进行观测。冠层上方同步观测气温、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量。
