The Installation and Use of a Snow Pillow to Monitor Snow Water Equivalent

Water and Environment Journal, 1995
ABSTRACTIn February 1993, a snow pillow was installed at Widdibank Fell near Cow Green reservoir (in Upper Teesdale) to monitor snow water equivalent.This paper describes existing snow‐measurement techniques in the UK and the site‐selection process and installation details for the snow pillow. Following a winter of more than 100 days with snow cover at

Automated Determination of Snow Water Equivalent by Acoustic Reflectometry

IEEE Transactions on Geoscience and Remote Sensing, 2009
Snow water equivalent (SWE) is commonly determined using gravimetric and depth measurement techniques. Previous research has demonstrated the ability to determine SWE from the propagation and reflection of acoustic waves. Despite the advantages of the acoustic technique, it has not been adapted so that SWE can be determined in an automated fashion ...

HUT snow emission model and its applicability to snow water equivalent retrieval

IEEE Transactions on Geoscience and Remote Sensing, 1999
The derivation, testing, and employment to parameter retrieval of the Helsinki University of Technology (HUT) snow microwave emission model is presented. The radiative transfer-based semi-empirical model describes the emission behavior of a homogeneous snowpack as a function of water equivalent (SWE), effective grain size, and density of snow ...

Local trends of snow water equivalents in the Alps

2022
<p>The spatial and temporal snow mass variation is clearly indicated as knowledge gap by the “IPCC Special Report on the Ocean and Cryosphere in a Changing Climate”, thus impeding current efforts to quantify historic and future trends.

Snow water equivalent estimation by microwave radiometry

Cold Regions Science and Technology, 1982
Abstract Snow water equivalent (SWE) is one of the most important parameters for accurate prediction of snowmelt runoff. Conventionally, SWE is monitored using observations made at widely scattered points in or around specific watersheds. Remote sensors, which provide data with better spatial and temporal coverage, can be used to improve the SWE ...

Prediction of snow-water equivalents in coniferous forests

Canadian Journal of Forest Research, 1981
Less snow accumulates under forest canopies than in small openings. Analysis of relationships between canopy cover and snow-water equivalents (SWE) for coniferous forests indicate substantial differences between areas and years. Many of these differences result from differences in the total amount of snowfall. The difference between SWE values in open

Monitoring Snow Water Equivalent in the Indian Himalayas

2021
The thesis deals with snow water equivalent (SWE) estimation using Polarimetric SAR (PolSAR) data at C- and X-band. SWE retrieval methodologies are developed using PolSAR, targeting mono-, dual-, and full-polarization SAR data. Field-based measurements have helped in the development and validation of the proposed algorithm.
