Description

This data set is part of the SnowEx 2020 and SnowEx 2021 campaigns and provides snow depth values at a 3.0 m spatial resolution, derived from point cloud digital terrain models. Snow depths are available for February 2020 and March 2021 for multiple areas in Colorado, Idaho, and Utah. These data were produced alongside <a href="https://doi.org/10.5067/VV382L4MQI7V">DEM</a> and <a href="https://10.5067/K67GKZQ9WUEI">Vegetation Height</a> data sets.
