2011-2015年千烟洲人工针叶林碳水通量观测数据集

江西千烟洲红壤丘陵地球关键带国家野外科学观测研究站是国内较早采用涡度相关技术开展人工林碳水通量观测和研究的野外站点之一, 持续获取并积累了一批长期观测数据。在前期发布数据的基础上, 通过标准化整编, 再次发布2011–2015年生态系统碳水通量和气象数据, 以充分发挥这些数据的科研价值, 进一步支撑国家及区域的碳汇评估, 并推动相关科学研究的发展。本次发布的数据集主要包括半小时尺度、日尺度、月尺度和年尺度的常规气象数据（近地面空气温度、冠层上方空气温度、近地面空气相对湿度、冠层上方空气相对湿度、近地面水汽压、冠层上方水汽压、近地面风速、冠层上方风速、风向、大气压、太阳辐射、净辐射、光合有效辐射、3层土壤温度、3层土壤体积含水量、降水量等）和碳水通量数据（生态系统总初级生产力、生态系统呼吸、净生态系统生产力、潜热通量、显热通量）。数据集共包括32个数据文件，其中：（1）碳水通量数据集包含2011–2015年间30分钟至整年等不同时间尺度的生态系统总初级生产力、生态系统呼吸、净生态系统生产力、潜热通量、显热通量等5个指标的数据；（2）气象数据集包括2011–2015年间30分钟至整年等不同时间尺度的空气温湿度、辐射等17个指标的数据。

The Qianyanzhou Red Soil Hilly Earth Critical Zone National Field Scientific Observation and Research Station in Jiangxi Province is one of the earliest field stations in China to adopt eddy covariance technology for carbon and water flux observation and research in planted forests, and has continuously acquired and accumulated a large set of long-term observation datasets. Based on previously published data, this study conducted standardized curation and reorganization, and now releases the ecosystem carbon and water flux and meteorological data from 2011 to 2015, so as to fully tap the scientific research value of these datasets, further support national and regional carbon sink assessments, and promote the development of related scientific research. The newly released dataset mainly includes routine meteorological data and carbon-water flux data at half-hourly, daily, monthly and annual scales. The routine meteorological data cover near-surface air temperature, air temperature above canopy, near-surface relative humidity, relative humidity above canopy, near-surface water vapor pressure, water vapor pressure above canopy, near-surface wind speed, wind speed above canopy, wind direction, atmospheric pressure, solar radiation, net radiation, photosynthetically active radiation (PAR), three-layer soil temperature, three-layer soil volumetric water content, precipitation, etc. The carbon-water flux data include Gross Primary Productivity (GPP), Ecosystem Respiration (Re), Net Ecosystem Productivity (NEP), Latent Heat Flux (LE) and Sensible Heat Flux (SH). The entire dataset consists of 32 data files in total, which are divided into two parts: (1) The carbon-water flux dataset contains data of the 5 aforementioned indicators across different time scales ranging from 30 minutes to full year during 2011–2015; (2) The meteorological dataset includes data of 17 indicators such as air temperature and humidity, radiation across different time scales ranging from 30 minutes to full year during 2011–2015.
