Greenhouse gas fluxes and their climatic controls from permafrost peatlands undergoing succession after permafrost thaw

The data provided in one xlsx file has two tabs: read me, and data. "Read me" contains descriptions of all column headers and data. It provides units of measurement for each. "Data" contains 1,071 net ecosystem exchange (NEE), 1,201 ecosystem respiration (ER), 1,007 gross primary production (GPP), and 960 methane (CH4) flux measurements collected from 2016-2018. It also contains where along two permafrost thaw transects the measurements were taken, the date they were taken, and environmental data (water table, soil temperature, photosynthetically active radiation) measured at the same time as each flux measurement. These flux measurements and corresponding environmental data were used to construct flux models and estimate annual greenhouse gfs balances.

本数据集存储于单个XLSX文件中，包含两个工作表：「说明文档（read me）」与「数据（data）」。其中「说明文档（read me）」工作表包含所有列标题与数据的说明信息，并给出了各字段的计量单位。「数据（data）」工作表包含2016至2018年间采集的1071条生态系统净交换（net ecosystem exchange, NEE）、1201条生态系统呼吸（ecosystem respiration, ER）、1007条总初级生产力（gross primary production, GPP）以及960条甲烷（methane, CH4）通量观测数据。此外，该数据集还记录了各观测点位在两处多年冻土融化样带上的具体位置、观测日期，以及与各通量观测同步获取的环境数据，涵盖地下水位、土壤温度与光合有效辐射。上述通量观测数据与配套环境数据已被用于构建通量模型，并估算年度温室气体（greenhouse gas, GHG）收支平衡。
