A dataset of carbon and water fluxes of the boreal forest ecosystem in Huzhong (2014 – 2018)

As an important component of the global carbon pool, boreal forests have attracted much attention in the research on climate change and carbon cycle due to their extreme sensitivity to climate warming. Located in the largest cold-temperate coniferous forest ecosystem nature reserve in China, China Boreal Forest Ecosystem Research Station (Huzhong Station) is one of the member stations of Chinese FLUX Observation and Research Network (ChinaFLUX), which has conducted long-term carbon and water flux observations of boreal forest ecosystems based on eddy covariance techniques since 2006. Following the ChinaFLUX data processing protocols, we collected the carbon and water fluxes and auxiliary meteorological environment observations of the boreal forest ecosystem at Huzhong Station from 2014 to 2018. Processing the data in a standard process, we formed a standardized dataset with four time scales, namely half-hourly, daily, monthly and yearly. The dataset is expected to provide data support for the studies on climate change, boreal forest ecosystem carbon, as well as water and energy balance.

寒温带针叶林（boreal forest）作为全球碳库的重要组成部分，因其对气候变暖具备极强的敏感性，在气候变化与碳循环研究领域备受学界关注。中国寒温带针叶林生态系统研究站（呼中站，China Boreal Forest Ecosystem Research Station）坐落于国内规模最大的寒温带针叶林生态系统自然保护区内，是中国通量观测研究联盟（Chinese FLUX Observation and Research Network，简称ChinaFLUX）的成员站之一。该站自2006年起便采用涡度协方差（eddy covariance）技术，对寒温带针叶林生态系统开展长期碳、水通量观测。本数据集遵循ChinaFLUX数据处理标准规程，收集了呼中站2014至2018年的寒温带针叶林生态系统碳、水通量及配套气象环境观测资料。经标准化流程处理后，最终构建得到包含半小时、日、月、年四个时间尺度的标准化数据集。本数据集可为气候变化研究、寒温带针叶林生态系统碳循环研究以及水热平衡研究提供可靠的数据支撑。
