Description

This data set contains the results of ground-penetrating radar surveys conducted at Cameron Pass, Colorado during the SnowEx20 campaign. Data include two-way travel time, lidar-measured snow depth, derived snow water equivalent, derived snow density, and derived relative permittivity. Ground-penetrating radar two-way travel times were sourced from two previously published data sets: <a href="https://doi.org/10.5067/U4Q3X27BMRR4">SnowEx20 Cameron Pass Ground Penetrating Radar, Version 1</a> and <a href="https://doi.org/10.5067/SRWGLYCB6ZC4">SnowEx21 Cameron Pass Ground Penetrating Radar, Version 1</a>. The new data presented here represents a recalculation of the snow water equivalent (SWE), snow density, and relative permittivity using terrestrial lidar scan (TLS) data.
