UAS remote sensing (Autel EVO II platform): Red-green-blue (RGB) imagery and derived products (Level 0-2 data), Seward Peninsula, Alaska, 2022

Airborne remote sensing data collected using a optical red-green-blue (RGB) sensor installed on an Autel EVO II unoccupied aerial system (UAS). This package includes data from 15 flights flown over the NGEE-Arctic Council Mile Marker (MM) 71, Kougarok MM64, and Teller MM27 sites on the Seward Peninsula, Alaska USA, in July 2022. This package provides the Level 0 (raw, unprocessed) data collected by the platform and sensors, and Level 1-2 processed products including digital surface models (DSM), photo orthomosaics, canopy height models (CHM) and digital terrain models (DTM). Ancillary aircraft data, flight mission parameters, and general flight conditions provided by the onboard flight and data collection computers are also included. Data and metadata are provided as image (*.jpg, *.tif), point cloud (*.laz), tabular (*.csv) and *.pdf formats. Raw images are compressed as tar.gz. The metadata documents contain flight campaign, platform, sensor, flight and file metadata, along with a description of the data and file naming scheme.The Next-Generation Ecosystem Experiments: Arctic (NGEE Arctic), was a 15-year research effort (2012-2027) 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).

下一代生态系统实验：北极（NGEE Arctic）是一项为期15年（2012年至2027年）的研究项目，旨在通过深化对富碳北极生态系统及其气候反馈机制的预测性认知，降低地球系统模型中的不确定性。该项目由美国能源部生物与环境研究办公室资助。
NGEE Arctic项目设有两个野外研究站点：其一位于阿拉斯加州乌特恰维克（旧称巴罗）附近的北坡巴罗环境观测站（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苏厄德半岛的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整合分析，NGEE Arctic项目为多尺度建模提供了更为完善的知识库，并助力美国能源部地球系统模型（能源超额计算地球系统模型，E3SM），尤其是其陆面模型模块（ELM），在全球泛北极尺度上优化了过程表征方式。
