Acoustic sounding of snow water equivalent
… wave was investigated as a means for determining Snow Water Equivalent (SWE) in cold wind-swept prairie and sub-alpine environments. Building on previous research conducted by investigators who have examined the propagation of sound in snow, digital signal processing was used to determine acoustic …

Spatial accumulation patterns of snow water equivalent in the southern Rocky Mountains
… point measurements may be taken within a given watershed to estimate snow water equivalent (SWE) due to cost limitations, which necessitates basin-scale estimation of SWE. Modeling often assumes consistency in the spatial distribution of SWE, which may not be correct. Identifying patterns and …

Ensemble Modeling of SWE Distribution in the Bitterroot Mountains, Montana, USA
<p>The spatial distribution of snow remains poorly understood at the landscape scale, particularly at high elevation where snow can be under-represented by our current system of monitoring. The transferability of the processes and physiography that drive the spatial distribution of snow require …

DISTRIBUTED ENERGETICS OF BOREAL FOREST SNOWMELT
The energetics of snowmelt under boreal forest canopies in central Saskatchewan were examined with respect to the influence of forest canopy structure on the snow cover depletionrate. The distribution of snow water equivalent was examined prior to melt and during melt in five distinct boreal forest …

Snow Accumulation and Melt Timing at High Elevations in Northwest Montana
The sensitivity of snowmelt driven water supply to climate variability and change is difficult to assess in the mountain west, where strong climatic gradients coupled with complex topography are sampled by sparse ground measurements. We developed a snowmelt model, which ingests daily satellite …

Hydrological modelling with components: the OMS3 NewAge-JGrass system
… system for forecasting and modelling of water resources in general at the basin scale. As a modern hydrological modelling, it is composed of two parts: (i) the system for data and results visualization based on the Geographic Information System uDig and (ii) the component based modelling …

ASSESSMENT AND POTENTIAL ADJUSTMENTS TO THE SNOW-RELATED ALGORITHMS IN BIOME-BGC, v4.2
Many watersheds throughout the mountain west are snow-melt dominated. Recent studies suggest that climatic shifts throughout the 20th century have diminished snowpack around the west, a trend that may accelerate in the future. Loss of critical snowpack could negatively affect the ecosystems and …

Spatiotemporal Dynamics of Snow-Free Frost Exposure in the Western Cordillera Seasonal Snow Zones
… ecosystems of the Western Cordillera, seasonal snowpack provides insulation for soils and vegetation against freezing temperatures. While temperatures are warming overall, concurrent declines in snowpack are removing this protective thermal blanket. This may lead to events where the ground …

Snow Hydrology and Streamflow Response to Snowmelt: A Case Study on SWE Dataset Comparisons, Regional Water Balance, and Snowmelt-Induced Runoff within the Smith River Watershed, Montana
Seasonal snowpacks in snow-dominated watersheds across the western United States play a critical role in sustaining regional water resources by delaying runoff and regulating streamflow. This research examined snow hydrology in the Smith River Watershed, located in Montana, USA, over five water …

Uncovering the Ground Thermal Regime of Coastal Labrador: The Influential Effects of Snow and Vegetation on Ground Temperatures
… is impacted by climate and local scale factors. Snow cover has been linked to differences in ground temperatures over short distances (< 5 m) because of its thermal buffering properties which slows energy exchanges between the ground and atmosphere. Accurate derivation and characterization of the …

PASSIVE MICROWAVE SATELLITE SNOW OBSERVATIONS FOR HYDROLOGIC APPLICATIONS
Melting snow provides an essential source of water in many regions of the world and can also contribute to devastating, wide-scale flooding. The objective of this research was to investigate the potential for passive microwave remotely sensed data to characterize snow water equivalent (SWE) and …

Wildfire impacts on western United States snowpack
Snowpack in the western U.S. is critical for water supply and is threatened by wildfires, which are becoming larger and more common. Numerous studies have examined impacts of wildfire on snow water equivalent (SWE), but many of these studies are limited in the number of observation locations, and …

Design and Development of an RF-SoC-Based Ultra-Wideband Radar for Remote Sensing of Snow
Snow is a crucial element of Earth's climate system, making its monitoring essential for the effective management of global water resources. High-resolution snow measurements are fundamental to climate modeling, hydrology, and water resource management. Currently, global snow monitoring relies on …
