InSAR for estimation of changes in snow water equivalent of dry snow
IGARSS 2000. IEEE 2000 International Geoscience and Remote Sensing Symposium. Taking the Pulse of the Planet: The Role of Remote Sensing in Managing the Environment. Proceedings (Cat. No.00CH37120), 2001This paper describes the theoretical relation between interferometric phase and changes in snow water equivalent (SWE) and show results from experiments using ERS- 1/2 tandem data. The main scattering contribution from a dry snow cover is from the snow-ground interface. However, the radar wave will be refracted in the snow.

Snow Depth and Snow Water Equivalent Estimation
2021Variation in regional and global snowfall significantly affects the ecological and climate systems, which is usually used for policy-making in water resource management and disaster prevention. The amount of snowfall is measured by two different parameters, snow depth and snow water equivalent (SWE). SWE is defined as the product of snow depth and snow

Analysis of GPR Data for Snow Water Equivalent
70th EAGE Conference and Exhibition incorporating SPE EUROPEC 2008, 2008GPR permits to map over large the thickness and density of snow pack: these parameters are required when the snow water equivalent has to be estimated. The results of GPR , conducted on a slope in the Alps in Northern Italy, are discussed. The data acquisition along several profiles was repeated in different period of the winter season.

The Installation and Use of a Snow Pillow to Monitor Snow Water Equivalent
Water and Environment Journal, 1995ABSTRACTIn 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, 2009Snow 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, 1999The 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 &#8220;IPCC Special Report on the Ocean and Cryosphere in a Changing Climate&#8221;, thus impeding current efforts to quantify historic and future trends.

Snow water equivalent estimation by microwave radiometry
Cold Regions Science and Technology, 1982Abstract 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 ...

The Canadian boreal snow water equivalent band
Atmosphere-Ocean, 2006Abstract Satellite and conventional snow water equivalent (SWE) dataseis reveal a well‐defined zone of high winter season SWE (>100 mm) that extends across the northern boreal forest of Canada. SWE coefficient of variation (CV) patterns derived from a monthly averaged (1978–2002) passive microwave derived time series show a high degree of interannual ...
