SnowEx20-21 Cameron Pass Derived Snowpack Relative Permittivities and Densities from Ground Penetrating Radar V001

Published by NASA NSIDC DAAC | National Aeronautics and Space Administration | Catalog Last Checked: June 09, 2026 at 10:31 PM | Dataset Last Updated: July 17, 2025
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: SnowEx20 Cameron Pass Ground Penetrating Radar, Version 1 and SnowEx21 Cameron Pass Ground Penetrating Radar, Version 1. 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.
