NGEE Arctic Leaf Spectral Reflectance and Transmittance, Barrow, Alaska, 2014-2016

Data were collected to characterize the leaf-level optical properties and albedo of dominant Arctic tundra species in the Barrow, AK area and to enable trait scaling. Measurements of full-spectrum (i.e. 350-2500nm) leaf spectral reflectance of Arctic plant species. Data were collected in Barrow, Alaska during the 2014-2016 period. This dataset contains 5 zipped folders, 4 csv, 4 xlsx, 1 txt, and 1 pdf files. The Next-Generation Ecosystem Experiments: Arctic (NGEE Arctic), was a research effort to reduce uncertainty in Earth System Models by developing a predictive understanding of carbon-rich Arctic ecosystems and feedbacks to climate. NGEE Arctic was supported by the Department of Energy's Office of Biological and Environmental Research. The NGEE Arctic project had two field research sites: 1) located within the Arctic polygonal tundra coastal region on the Barrow Environmental Observatory (BEO) and the North Slope near Utqiagvik (Barrow), Alaska and 2) multiple areas on the discontinuous permafrost region of the Seward Peninsula north of Nome, Alaska. Through observations, experiments, and synthesis with existing datasets, NGEE Arctic provided an enhanced knowledge base for multi-scale modeling and contributed to improved process representation at global pan-Arctic scales within the Department of Energy's Earth system Model (the Energy Exascale Earth System Model, or E3SM), and specifically within the E3SM Land Model component (ELM).本数据集旨在表征美国阿拉斯加州巴罗地区优势北极苔原物种的叶片级光学特性与反照率，并支撑性状尺度转换研究。研究采集了北极植物物种的全光谱（350-2500nm）叶片光谱反射率数据，采集时段为2014至2016年，地点位于阿拉斯加巴罗。本数据集包含5个压缩文件夹、4个CSV文件、4个XLSX文件、1个TXT文件及1个PDF文件。下一代北极生态系统实验（Next-Generation Ecosystem Experiments: Arctic, NGEE Arctic）是一项研究计划，旨在通过构建对富碳北极生态系统的预测性认知及其对气候的反馈机制，降低地球系统模型的不确定性。该项目由美国能源部生物与环境研究办公室资助。NGEE Arctic设有两个野外研究站点：其一位于阿拉斯加州乌特恰维克（原巴罗）附近的北坡巴罗环境观测站（Barrow Environmental Observatory, BEO）内的北极多边形苔原沿海区域；其二位于阿拉斯加州诺姆以北的苏华德半岛不连续永久冻土区的多个区域。通过观测、实验与现有数据集的综合分析，NGEE Arctic为多尺度建模提供了更完善的知识库，并助力美国能源部地球系统模型（能源极端尺度地球系统模型，Energy Exascale Earth System Model, E3SM），尤其是其E3SM陆面模型组件（ELM），在全球泛北极尺度下提升了过程表征能力。
