Data for: "Statistical upscaling of ecosystem CO2 fluxes across the terrestrial tundra and boreal domain: regional patterns and uncertainties"

<strong>Description of the data</strong> This dataset is a compilation of eddy covariance and chamber measurements of annual and growing season carbon dioxide (CO₂)fluxes of gross primary productivity (GPP), ecosystem respiration (ER), and net ecosystem exchange (NEE). The dataset includes flux measurements conducted during 1990–2015 from 148 terrestrial high-latitude tundra and boreal sites. The fluxes and supporting metadata were synthesized by conducting a literature survey, organizing a community call to retrieve unpublished data, and leveraging the available data in FLUXNET2015. Further, we used geospatial products to derive environmental data to these sites. More details can be found in Virkkala et al. "Statistical upscaling of ecosystem CO₂ fluxes across the terrestrial tundra and boreal domain: regional patterns and uncertainties" (in review). <strong>Files in this repository</strong> This repository consists of two datasets: annual_growingseason_CO2flux.csv includes the data and annual_growingseason_CO2flux_metadata.csv provides a description of the columns. <strong>Article citation</strong> Virkkala, A.-M., Aalto, J., Rogers, B.

Statistical upscaling of ecosystem CO₂ fluxes across the terrestrial tundra and boreal domain: regional patterns and uncertainties (in review since Feb, 2021).数据集说明 本数据集整合了1990—2015年间，针对148个陆地高纬度苔原与寒带站点的涡度协方差（eddy covariance）与箱法通量测量数据，涵盖总初级生产力（GPP, gross primary productivity）、生态系统呼吸（ER, ecosystem respiration）及生态系统净交换（NEE, net ecosystem exchange）的年度与生长季二氧化碳（CO₂）通量。本数据集的通量数据与配套元数据通过文献调研、发起社区数据征集以获取未公开观测资料，以及整合FLUXNET2015中的现有数据合成得到。此外，本研究通过地理空间产品推导得到各站点的环境辅助数据集。更多详细信息可参见Virkkala等人的研究"Statistical upscaling of ecosystem CO₂ fluxes across the terrestrial tundra and boreal domain: regional patterns and uncertainties"（审稿中）。 本仓库包含文件 本仓库包含两份数据集：`annual_growingseason_CO2flux.csv` 存储核心观测数据，`annual_growingseason_CO2flux_metadata.csv` 用于说明各数据列的具体含义。 文献引用 Virkkala, A.-M., Aalto, J., Rogers, B.
