Description

This data set contains snow water equivalent (SWE) and snow density raster data derived from a lidar-based snow depth data set (<a href="https://doi.org/10.5067/M9TPF6NWL53K">SnowEx20 Grand Mesa IOP QSI Lidar Snow Depth Data, Version 1</a>), a lidar-based digital terrain model (<a href="https://doi.org/10.5067/2EHMWG4IT76O">ASO L4 Lidar Point Cloud Digital Terrain Model 3m UTM Grid, Version 1</a>), and two GPR data sets (<a href="https://doi.org/10.5067/Q2LFK0QSVGS2">SnowEx20 Grand Mesa IOP BSU 1 GHz Multi-polarization GPR, Version 1</a> and <a href="https://doi.org/10.5067/WE9GI1GVMQF6">Mesa IOP UNM 800 and 1600 MHz MALA GPR, Version 1</a>). Data was collected during the NASA SnowEx 2020 field campaign in Grand Mesa, Colorado.
