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>.
