Dataset for "Inter-annual variability of summer net ecosystem CO2 exchange in High Arctic tundra" by Braybrook et al.

A dataset with 30 min net ecosystem carbon dioxide exchange measurements (NEE) with and without gap-filling, derived component fluxes, gross primary productivity (GPP) and ecosystem respiration (R_eco) and ancillary weather variables used to investigate how summer NEE, GPP and R_eco varied over five years (2008, 2009, 2010, 2012, and 2014) at the Cape Bounty Arctic Watershed Observatory (CBAWO) (74.92˚N, 109.58˚W). The eddy covariance technique was used to measure NEE and a combined light and temperature response model was used to partition NEE into GPP and R_eco. Further measurement and data processing details are described in the research paper, "Inter-annual variability of summer net ecosystem CO₂ exchange in High Arctic tundra", JGR Biogeosciences, 2021.本数据集包含30分钟步长的净生态系统二氧化碳交换量（net ecosystem carbon dioxide exchange, NEE）序列，涵盖间隙填充与非间隙填充两种处理版本，同时附带其衍生的组分通量：总初级生产力（gross primary productivity, GPP）与生态系统呼吸（R_eco），以及用于辅助分析的配套气象变量。本数据集旨在探究角邦迪北极流域观测站（Cape Bounty Arctic Watershed Observatory, CBAWO，地理坐标74.92°N, 109.58°W）在2008、2009、2010、2012及2014五个年度的夏季NEE、GPP与R_eco的年际变化规律。数据集采用涡度协方差技术（eddy covariance technique）获取NEE数据，并通过光温联合响应模型将NEE拆解为GPP与R_eco。更多测量与数据处理细节可参阅2021年发表于《地球物理研究杂志：生物地球科学分册》（JGR Biogeosciences）的研究论文《北极高寒苔原夏季净生态系统CO₂交换的年际变异性》（原英文标题：Inter-annual variability of summer net ecosystem CO₂ exchange in High Arctic tundra）。
