Vegetation Warming Experiment: Landscape-scale digital camera imagery for vegetation phenology, Utqiagvik (Barrow), Alaska, 2017

Images captured using a StarDot NetCam SC phenocamera looking east from the top of the Barrow Environmental Observatory (BEO) Sled Shed, Barrow (now Utqiagvik), Alaska. The camera was installed to remotely monitor plant phenology and operation of the BNL TEST group's ZPW (Zero Power Warming) chambers during the growing season of 2017. Images were captured from early spring (24 April) through to late fall (15 November). Snowmelt, vegetation growth and senescence, and snow accumulation were captured. Images were uploaded to the BNL FTP server every 10 minutes. jpg images have been compressed in *.tar.gz format (12.1 GB) and additional information in *.pdf and *.txt 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).

本数据集的图像由StarDot NetCam SC型物候相机拍摄，拍摄点位位于美国阿拉斯加州巴罗（现名乌特恰维克）的巴罗环境观测站（Barrow Environmental Observatory, BEO）雪橇棚顶部，朝东拍摄。
该相机于2017年生长季安装，用于远程监测植物物候状态，以及布鲁克黑文国家实验室（Brookhaven National Laboratory, BNL）TEST团队的零功率增温箱（Zero Power Warming, ZPW）的运行状况。
图像拍摄时段为初春（4月24日）至深秋（11月15日），记录了融雪、植被生长与衰老以及积雪累积的过程。
图像每10分钟自动上传至BNL的FTP服务器，JPEG格式图像已打包为*.tar.gz压缩文件（总大小12.1 GB），另有*.pdf与*.txt格式的附加信息文件。
下一代北极生态系统实验（Next-Generation Ecosystem Experiments: Arctic, NGEE Arctic）是一项旨在通过构建富碳北极生态系统的预测性认知及其对气候的反馈机制，降低地球系统模型不确定性的研究计划。
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：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（BEO）内的北极多边形苔原沿海区域；2）阿拉斯加州诺姆以北苏厄德半岛的不连续永久冻土区域内的多处点位。
通过观测、实验以及与现有数据集的综合分析，NGEE Arctic为多尺度建模提供了增强型知识库，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的过程表征精度提升。
