Samford Ecological Research Facility 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 Samford flux station is situated on an improved (Paspalum dilatum) pasture in the humid subtropical climatic region of coastal south-east Queensland. Located only 20km from the centre of Brisbane city, Samford Valley provides an ideal case study to examine the impact of urbanisation and land use change on ecosystem processes. The valley covers an area of some 82km2 and is drained in the southern regions by the Samford creek, which extends some 13km to Samford Village and into the South Pine River. The Samford Valley is historically a rural area experiencing intense urbanisation, with the population increasing almost 50% in the 10 years to 2006 (Morton Bay Regional Council, 2011). Within the Samford valley study region, the Samford Ecological Research Facility (SERF) not only represents a microcosm of current and historical land uses in the valley, but provides a unique opportunity to intensively study various aspects of ecosystem health in a secure, integrated and long term research capacity. Mean annual minimum and maximum temperatures at a nearby Bureau of Meteorology site are 13.1°C and 25.6°C respectively while average rainfall is 1102mm.

本数据集发布内容包含采用涡度相关（eddy covariance）技术，对半干旱桉树林地内地表与大气边界层间能量和物质交换开展的通量塔观测数据。该数据已参照Isaac等人（2017年）的方法，使用PyFluxPro（v3.3.0）完成处理，相关文献DOI为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，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）。有关数据处理等级的更多详情，请参阅https://github.com/OzFlux/PyFluxPro/wiki。

萨姆福德通量站坐落于昆士兰州东南部沿海湿润亚热带气候区内的改良型雀稗（Paspalum dilatum）牧场中。萨姆福德谷距布里斯班市中心仅20公里，是探究城市化与土地利用变化对生态系统过程影响的理想案例研究区域。该谷总面积约82平方公里，南部区域由萨姆福德溪流经，该溪流全长约13公里，延伸至萨姆福德村并汇入南派恩河。萨姆福德谷历史上为乡村区域，目前正经历快速城市化，截至2006年的十年间人口增幅近50%（莫顿湾区域议会，2011年）。在萨姆福德谷研究区域内，萨姆福德生态研究设施（Samford Ecological Research Facility, SERF）不仅是该流域当前与历史土地利用的缩影，还为在安全、集成且长期的研究框架下深入开展生态系统健康多维度研究提供了独特契机。邻近的澳大利亚气象局（Bureau of Meteorology）观测站点数据显示，该区域年平均最低气温与最高气温分别为13.1°C和25.6°C，年平均降雨量为1102毫米。更多站点相关信息，请参阅https://www.tern.org.au/tern-observatory/tern-ecosystem-processes/samford-peri-urban-supersite/。
