FLUXNET 2015数据集提供了生态系统规模的数据，包括生物圈和大气之间的CO2，水和能量交换，以及其他气象和生物测量，来自地球仪的212个站点（超过1500个站点-年，直到并包括2014年）。这些独立管理和运营的网站自愿贡献其数据以创建全球数据集。对数据进行质量控制，并使用统一的方法进行处理，以提高各研究中心的一致性和相互可比性。该数据集已被用于许多应用，包括生态生理学研究、遥感研究以及生态系统和地球系统模型的开发。FLUXNET 2015包括衍生数据产品，如填补空白的时间序列，生态系统呼吸和光合吸收估计，不确定性估计，以及本文首次提出的测量数据的元数据。此外，这些网站中有206个是首次在知识共享（CC-BY 4.0）许可下发布的。本文详细介绍了这个增强的数据集和处理方法，现在以开源代码的形式提供，使数据集更加易于访问、透明和可复制。
The FLUXNET2015 dataset provides ecosystem-scale data on CO2, water, and energy exchange between the biosphere and the atmosphere, and other meteorological and biological measurements, from 212 sites around the globe (over 1500 site-years, up to and including year 2014). These sites, independently managed and operated, voluntarily contributed their data to create global datasets. Data were quality controlled and processed using uniform methods, to improve consistency and intercomparability across sites. The dataset is already being used in a number of applications, including ecophysiology studies, remote sensing studies, and development of ecosystem and Earth system models. FLUXNET2015 includes derived-data products, such as gap-filled time series, ecosystem respiration and photosynthetic uptake estimates, estimation of uncertainties, and metadata about the measurements, presented for the first time in this paper. In addition, 206 of these sites are for the first time distributed under a Creative Commons (CC-BY 4.0) license. This paper details this enhanced dataset and the processing methods, now made available as open-source codes, making the dataset more accessible, transparent, and reproducible.
