Snow metamorphism: a fractal approach [PDF]
Phys. Rev. E 82, 036103 (2010), 2010 Snow is a porous disordered medium consisting of air and three water phases: ice, vapour and liquid. The ice phase consists of an assemblage of grains, ice matrix, initially arranged over a random load bearing skeleton. The quantitative relationship between density and morphological characteristics of different snow microstructures is still an open ...

Estimating snow cover from publicly available images [PDF]
, 2015 In this paper we study the problem of estimating snow cover in mountainous regions, that is, the spatial extent of the earth surface covered by snow. We argue that publicly available visual content, in the form of user generated photographs and image feeds from outdoor webcams, can both be leveraged as additional measurement sources, complementing ...

Dominance of grain size impacts on seasonal snow albedo at deforested sites in New Hampshire [PDF]
, 2017 Snow cover serves as a major control on the surface energy budget in temperate regions due to its high reflectivity compared to underlying surfaces.

Hierarchical Integrated Spatial Process Modeling of Monotone West Antarctic Snow Density Curves [PDF]
the Annals of Applied Statistics 2021, Vol. 15, No. 2, 556-571, 2020 Snow density estimates below the surface, used with airplane-acquired ice-penetrating radar measurements, give a site-specific history of snow water accumulation. Because it is infeasible to drill snow cores across all of Antarctica to measure snow density and because it is critical to understand how climatic changes are affecting the world's largest ...

Micrometeorological processes driving snow ablation in an Alpine catchment [PDF]
, 2011 Mountain snow covers typically become patchy over the course of a melting season. The snow pattern during melt is mainly governed by the end of winter snow depth distribution and the local energy balance.

Particulate and water-soluble carbon measured in recent snow at Summit, Greenland [PDF]
, 2007 Water-soluble organic carbon (WSOC), waterinsoluble particulate organic carbon (WIOC), and particulate elemental carbon (EC) were measured simultaneously for the first time on the Greenland Ice Sheet in surface snow and in a 3-meter snow pit.

The effects of variation in snow properties on passive microwave snow mass estimation [PDF]
, 2012 Estimating snow mass at continental scales is difficult, but important for understanding land-atmosphere interactions, biogeochemical cycles and the hydrology of the Northern latitudes.

LMQFormer: A Laplace-Prior-Guided Mask Query Transformer for Lightweight Snow Removal [PDF]
, 2022 Snow removal aims to locate snow areas and recover clean images without repairing traces. Unlike the regularity and semitransparency of rain, snow with various patterns and degradations seriously occludes the background. As a result, the state-of-the-art snow removal methods usually retains a large parameter size.

Soluble species in aerosol and snow and their relationship at Glacier 1, Tien Shan, China [PDF]
, 1998 Simultaneous sampling of aerosol (n = 20) and snow (n = 114) was made at Glacier 1, Tien Shan, between May 19 and June 29, 1996. Similar temporal patterns of some major ion (calcium, magnesium, potassium, sodium, chloride, and sulfate) concentrations ...

Marine Snow Removal Benchmarking Dataset [PDF]
, 2021 This paper introduces a new benchmarking dataset for marine snow removal of underwater images. Marine snow is one of the main degradation sources of underwater images that are caused by small particles, e.g., organic matter and sand, between the underwater scene and photosensors.
