摘要

This article presents a new nondestructive characterization system for the extraction of both snow density and liquid water content (LWC). The experiment primarily measures the relative complex permittivity of snow(epsilon(s)) at microwave frequencies at 4-6 GHz. The density and LWC are then deduced with high accuracy from an empirical model of the literature that has been experimentally validated in this study.
