WebTC - Recent WebGoals / Objectives The goal of this research is to develop and implement a novel method of measuring both snow water equivalent (SWE) and snow liquid water content (LWC) using observation of Global Navigation Satellite System (GNSS, of which GPS is a subset) signals that have transmitted through the snowpack. This system promises to create an …
WebThese data-derived products include continuous multi-year high-rate GNSS, seismogeodetic, and meteorological time series, a catalog of transient deformation in tectonically active areas known for aseismic motion such as ETS with focus in Cascadia, and continuous estimation and cataloging of total near-surface water content derived … WebAug 30, 2012 · The amount of water stored in snowpack is the single most important measurement for the management of water supply and flood control systems. The available water content in snow is called the snow water equivalent (SWE). The product of snow density and depth provides an estimate of SWE. In this paper, snow depth and density …
