Ground radar probing the snowpack (SnowEx 2023)
What it measures. Ground-based radar readings of the snowpack, giving how long the radar signal takes to travel through the snow, the calculated snow depth, and the snow water equivalent (how much water the snow holds).
How it's made. Collected by 1 GHz ground-penetrating radar dragged across snow at a site in northern Alaska during the NASA SnowEx 2023 field campaign in March 2023.
How & where you'd use it. Helps scientists measure and validate snowpack depth and water content, useful for water-supply estimates and for checking satellite and airborne snow data.

Official description
This data set contains the results of 1 GHz ground-penetrating radar surveys conducted at the Upper Kuparuk/Toolik (UKT) site in northern Alaska, USA as part of the NASA SnowEx 2023 field campaign. Data were collected between 08 Mar 2023 to 15 Mar 2023, spatially coinciding with snow pit locations and along transects between snow pits. Data include two-way travel (TWT) time, calculated snow depth, and calculated snow water equivalent (SWE). Raw GPR data are available as <a href="https://nsidc.org/data/SNEX23_CRREL_GPR_Raw/versions/1">SnowEx23 CRREL Ground Penetrating Radar Raw, Version 1</a>.
