2003–2005年中国通量观测研究联盟（ChinaFLUX）碳水通量观测数据集

本数据集为中国通量观测研究联盟（ChinaFLUX）首批观测站点的生态系统通量观测数据，包括森林、草地和农田在内的8个典型生态系统，并基于ChinaFLUX数据处理体系形成了标准化的生态系统碳水通量和关键气象要素数据集。本数据集可以为分析我国典型陆地生态系统对全球变化的响应及其机制提供重要的科学知识和数据基础。数据集由长白山、千烟洲、鼎湖山、西双版纳、内蒙古、禹城、海北和当雄8个台站的观测数据子集组成，每个子集分为半小时、日尺度2个数据产品表格。每个数据子集的指标包含生态系统CO2通量、潜热通量、显热通量、空气温度、土壤温度、土壤湿度、降水、总辐射和光合有效辐射。

This dataset comprises ecosystem flux observation data from the first batch of monitoring sites of the ChinaFLUX (China Flux Observation and Research Network), covering 8 typical ecosystems including forests, grasslands and croplands. Standardized datasets of ecosystem carbon and water fluxes as well as key meteorological variables have been developed based on the ChinaFLUX data processing system. This dataset provides a crucial scientific and data foundation for analyzing the responses of typical terrestrial ecosystems in China to global change and their underlying mechanisms. The dataset consists of observational data subsets from 8 stations: Changbaishan, Qianyanzhou, Dinghushan, Xishuangbanna, Inner Mongolia, Yucheng, Haibei, and Dangxiong. Each subset includes two data product tables at half-hourly and daily temporal scales respectively. The metrics included in each data subset are ecosystem CO₂ flux, latent heat flux, sensible heat flux, air temperature, soil temperature, soil moisture, precipitation, global solar radiation, and photosynthetically active radiation (PAR).
