SnowEx20 Boise Center Aerospace Laboratory 1 m Resolution Snow Depth, Topographical, and Vegetation Structural Metrics, Version 1

The data set consists of 1 m resolution snow depth, elevation, aspect, slope, canopy percent cover, canopy height, and foliage height diversity (FHD) measurements at 0.5 m, 1 m, and 2 m from the NASA SnowEx Grand Mesa, Colorado study site. Data are derived from Airborne Snow Observatory (ASO) snow-off lidar flights from September 2016 (ASO L4 Lidar Point Cloud Digital Terrain Model 3m UTM Grid, Version 1) and Quantum Spatial snow-on lidar flights from February 2020 (SnowEx20-21 QSI Lidar DEM 0.5m UTM Grid, Version 1).

本数据集包含来自美国国家航空航天局（NASA）科罗拉多州格兰德梅萨（Grand Mesa）雪实验（SnowEx）研究区域内，在距地面0.5米、1米及2米高度处采集的1米分辨率雪深、高程、坡向、坡度、冠层百分覆盖率、冠层高度以及叶高多样性（Foliage Height Diversity, FHD）测量数据。数据源自2016年9月机载雪观测站（Airborne Snow Observatory, ASO）的无雪激光雷达飞行任务（对应数据为ASO L4激光雷达点云数字地形模型3米UTM网格，版本1），以及2020年2月Quantum Spatial开展的有雪激光雷达飞行任务（对应数据为SnowEx20-21 QSI激光雷达DEM 0.5米UTM网格，版本1）。
