Dataset Information

Conventions: CF-1.8
title: Grand Mesa 2020 FMCW Radar Autopicked Snow Depths
summary: Processed radargrams from the results from a novel, semi-automated method for analyzing radar data collected over snowpack to estimate snow depth which can be used to calculate the amount of water held in the snowpack,or Snow Water Equivalent (SWE).
