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

Review of snow water equivalent retrieval methods using spaceborne passive microwave radiometry

International Journal of Remote Sensing, 2020
The physical properties of a snowpack strongly influence the emissions from the substratum, making snow property retrievals feasible by means of the surface brightness temperature observed by passive microwave sensors. Depending on the spatial resolution

Analysis of GPR Data for Snow Water Equivalent

70th EAGE Conference and Exhibition incorporating SPE EUROPEC 2008, 2008
GPR 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.

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.

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 ...

Validation of remotely sensed estimates of snow water equivalent using multiple reference datasets from the middle and high latitudes of China

, 2020
A key variable describing the mass of seasonal snow cover is snow water equivalent (SWE), which plays an important role in hydrological applications, weather forecasting and land surface process simulations. In this paper, the accuracy of an SWE product,

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 ...

Estimation of the spatiotemporal dynamic of snow water equivalent at mountain range scale under data scarcity.

Science of the Total Environment, 2020
The snow dynamics in alpine systems play a significant role in the hydrosphere, biosphere, and anthroposphere interfaces of these regions. The storage of water resources as snow is essential for ecosystems, human consumption, tourism, and hydropower in ...
