SnowEx23 Airborne Lidar Scans Raw, Version 1

This data set provides raw lidar data from two regions of Alaska, USA collected as part of the NASA SnowEx 2023 field campaign. The study sites include a boreal forest environment in the Fairbanks region of central Alaska (the Bonanza Creek Experimental Forest, Caribou Poker Creek watershed, and Farmer’s Loop/Creamer’s Field) and a coastal tundra environment in the North Slope region of the northern Alaska coastal plain (Arctic coastal plain and Upper Kuparuk Toolik). Processed data, including digital terrain models, snow depth, and canopy height derived from Point Cloud Digital Terrain Models (PCDTMs) are available as SnowEx23 Airborne Lidar-Derived 0.25M Snow Depth and Canopy Height, Version 1.

本数据集提供了美国阿拉斯加州两个区域的原始激光雷达（lidar）数据，这些数据系作为美国国家航空航天局（NASA）SnowEx 2023野外科考项目的组成部分采集所得。研究站点涵盖两类环境：其一为阿拉斯加中部费尔班克斯地区的寒温带针叶林环境，包含博南扎溪实验森林、驯鹿波克里克流域以及农民环路/克里默田野；其二为阿拉斯加北部沿海平原北坡区域的沿海苔原环境，包含北极沿海平原与上库帕鲁克-图利克区域。经处理的数据包含基于点云数字地形模型（Point Cloud Digital Terrain Models, PCDTMs）衍生得到的数字地形模型、雪深数据与冠层高度数据，相关处理成果以《SnowEx23机载激光雷达衍生0.25米雪深与冠层高度数据集（版本1）》形式对外发布。
