Description

This data set is part of the SnowEx 2021 campaign and provides bare Earth digital elevation models (DEM) acquired by a scanning lidar system at a 0.5 m spatial resolution, and derived from point cloud digital terrain models. DEMs are available for September 2021 and from multiple areas in Colorado, Idaho, and Utah. These data were produced alongside <a href="https://doi.org/10.5067/8RBIUIPEUJ7Z">Vegetation Height</a> and <a href="https://doi.org/10.5067/VBUN16K365DG">Snow Depth</a> data sets.
