Expansion of high-latitude deciduous forests driven by interactions between climate warming and fire: Modeling Archive

This Modeling Archive is in support of an NGEE Arctic publication. More information in the related references. The dataset is a model (ecosys) output used in a study that examined the potential future shifts in high-latitude vegetation types (PFTs) driven by changes in 21st century climate and fire. The study highlights the importance of mechanistically representing differences in plant functional traits on current and possible 21st century trajectories of Alaskan PFTs. This dataset package includes 13 files in pdf, csv, and nc formats. 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).

本数据集为某研究中使用的生态系统（ecosys）模型输出产物，该研究聚焦于21世纪气候与火灾变化驱动下的高纬度植被功能型（Plant Functional Types, PFTs）未来潜在转变。此项研究强调了在当前及21世纪阿拉斯加植被功能型变化轨迹中，机制性刻画植物功能性状差异的重要性。
本数据集套件包含13个格式分别为pdf、csv与nc的文件。
下一代北极生态系统实验（Next-Generation Ecosystem Experiments: Arctic, NGEE Arctic）是一项旨在通过深化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，以降低地球系统模型不确定性的研究项目。
该项目由美国能源部生物与环境研究办公室资助。
NGEE Arctic项目设有两处野外研究站点：1）位于阿拉斯加州乌特恰维克（原巴罗）附近北坡的巴罗环境观测站（Barrow Environmental Observatory, BEO）内的北极多边形苔原沿海区域；2）位于阿拉斯加州诺姆以北苏华德半岛不连续多年冻土区的多处区域。
通过观测、实验以及与现有数据集的综合分析，NGEE Arctic为多尺度建模构建了更完善的知识库，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），尤其是其陆面模型组件（ELM），在全球泛北极尺度下优化了过程表征能力。
