Assessing Variabilities of Extreme Precipitation and Snow Depth Using Climate and Stochastic Models
… events. Specifically, heavy rainfall and rapid snowmelt have triggered extensive flooding in multiple provinces. As global temperatures rise and weather patterns change, the world must remain vigilant and adapt approaches to address the evolving threat of floods. To address this issue, we …

Development and Optimization of Airborne FMCW Radars for High-Resolution Snow Depth Measurements
… population relies on glaciers and seasonal snowpacks for freshwater supply. In the United States, the Colorado River Basin (CRB) gets 75% of its water from snow melt; it constitutes the water supply of 40 million people in seven states, two countries, and 5.5 million irrigated acres of land. …

Practical snow depth sampling around six snow telemetry (SNOTEL) stations in Colorado and Wyoming, United States
… Service (NRCS) operates about 700 automated snowpack telemetry (SNOTEL) measurement stations. These stations measure snow depth (SD), snow water equivalent (SWE), air temperature and precipitation. To assess how representative the stations are of the surrounding 1 km2 area, a set of …

Improving Snow Deposition Magnitude and Heterogeneity Using Historic Snow Patterns in the California, USA, Sierra Nevada
Mountainous snow-covered landscapes in the Western United States behave like natural reservoirs, storing water during cold winter periods and sustaining snowmelt-driven streamflow vital for agriculture, municipalities, hydropower generation, and local ecosystems. In these regions, the timing and …

Validation of NOAA Interactive Snow Maps in the North American region with National Climatic Data Center Ground-based Data
"Both the areal coverage of snow and the volume of water in its subsequent melt are of concern for the creation and maintenance of both hydroelectric power and local water supply. The interactive multisensor snow and ice mapping system (IMS) is a geographic interactive system that allows for both …

Quantifying seasonal snow using very-high-resolution stereo optical satellite images
Seasonal snow is one of the most dynamic components of the cryosphere. This water resource serves multiple roles in ecohydrology, climate modulation, and nutrient cycling. Measuring snow distributions is critical to estimating water storage and to predict melt volumes and timing. Interconnected, …

Morphological approaches to understanding Antarctic Sea ice thickness
… quantity, even in the satellite era. The snow surface elevation, which is far easier to measure, cannot be directly converted into sea ice thickness estimates without knowledge or assumption of what proportion of the snow surface consists of snow and ice. We do not fully understand how …

Homogenization and analysis of hydrological time series
… it for any application. The homogenization of snow depth data, in particular, is a challenging task. Up to now, it has been performed analyzing available metadata, which often present contradictions and are rarely complete. In this work, we present a procedure to test the homogeneity of snow …

Nitrogen uptake patterns by snow addition in a sub-Arctic dry heath tundra ecosystem
… by climate change,which particularly affectssnow accumulation and the length of the growing season. In this study, I examined the influence of snow depth on parameters such as water content, soil temperature, microbial activity, and nutrient availability and investigated their implications …

Shrub expansion in the low Arctic: The influence of snow and vegetation feedbacks on nitrogen cycling
… Arctic. Tall shrubs accumulate relatively deep snowcover, raising winter soil temperature minima, enhancing microbial activity and promoting nitrogen mobilization that may then be taken up by shrubs. However, it has yet to be determined if shrubs can acquire winter-mobilized nitrogen, and if so, …

Changes of Winter Severity in Arkansas during 1901-2100
… temperature, minimum daily temperature, daily snowfall, and daily snow depth. When the snowfall and snow depth were missing, they can be estimated using daily temperature and precipitation. Then the estimated snowfall and snow depth can be subsequently used to quantify the winter severity. The …

L'apport de la télédétection à un modèle de neige appliqué à un système d'aide à la gestion des barrages dans le sud du Québec
… hydrological model (MOHYSE), which integrates a snow model (SPH-AV), for the management of dams in the south of Québec. It appears that the estimation of the water quantity of snowmelt in spring remains a variable with a large uncertainty. This research aims to evaluate the potential of remote …

Natural Hazards Monitoring Using Multiple Remote Sensing Techniques and Machine Learning Algorithms
… 2021, an unprecedented winter storm dumped the snow record in Texas. It claimed hundreds of lives and evolved into a major disaster nationalwide. This study uses the differential coherence from Sentinel-1 Synthetic Aperture Radar imagery to characterize the surface disturbance due to this winter …

A Food Habits Study of Whitetail Deer In The Black Hills
… (Quercus macrocarpa), and lichens (Usnea sp.). Snow depth was the most important factor affecting availability. As snow depth increased common juniper use increased while Oregon grape and bearberry use decreased. Forbs were not important food items during fall and winter. Significant differences …

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 …
