SNOW-WATER EQUIVALENT MEASUREMENT USING NATURAL GAMMA EMISSION
SNOW-WATER EQUIVALENT MEASUREMENT NATURAL GAMMA EMISSION
2009/10/29
The natural gamma radiation emitted by potassium, uranium and thorium
is attcnuated by snow. This attenuation depends on the water-equivalent
of the snow layer. Air absorption coefficients were dete...
Estimating the Variance of Airborne Snow Water Equivalent Estimates Using Computer Simulation Techniques
Airborne Snow Water Equivalent Estimates Simulation Techniques
2009/10/27
Estimates of snow water equivalent derived from measurements of the attenuation
of terrestrial gamma radiation vary as a function of several known sources
of error. In this study, a computer simulat...
A Neural Network Approach to Inversion of Snow Water Equivalent from Passive Microwave Measurements
Neural Network Approach Snow Water Equivalent Passive Microwave Measurements
2009/10/26
The inversion of snow water equivalent, SWE, from passive microwave remote
sensing measurements may be accomplished by using a neural network trained
with a dense media multiple scattering model. Br...

Uncertainty Spatial Estimates Areal Snow Water Equivalent
2009/10/23
With the increased demand for water in the United States, particularly in the
West, it is essential that water resources be accurately monitored. Consequently,
the National Weather Servicc (NWS) mai...
Modelling the spatial variability of snow water equivalent at the catchment scale
snow water equivalent catchment scale
2009/5/13
The spatial distribution of snow water equivalent (SWE) is modelled as a two parameter gamma distribution. The parameters of the distribution are dynamical in that they are functions of the number of ...
