This review (1995-2009) examines the development of snow mapping over time, and explores the application of modern technology to the measurement of snow distribution and characterization. Some advantages and limitations of current snow mapping
methods and techniques are discussed, as are their potential to facilitate future snow mapping. It is demonstrated that advances in remote sensing technology and ground-based measurement devices have upgraded snow mapping to a fully digital process during
recent decades, and it is anticipated that three-dimensional snow mapping will facilitate a fundamental step toward a new generation of snow observation techniques in the coming years.
Snowpack characteristics of Vestfonna and De Geerfonna (Nordaustlandet, Svalbard) - a spatiotemporal analysis based on multiyear snow-pit data

The AA. present snow cover information obtained from 22 snow pits that were dug on Vestfonna during 2007–2010 in spring (April/May) and summer (August). Snow-cover information acquired from 4 snow pits on adjacent De Geerfonna is also incorporated
in this study. Field data are analysed regarding snow stratigraphy, snow density, snow hardness and snow temperature. Results reveal mean snow densities for the snowpack of Vestfonna with no apparent spatial or interannual variability. A distinctly higher value
was obtained for De Geerfonna. A spatial comparison of snow water equivalents above the previous end-of-summer surface serves for obtaining insights into the spatial distribution of snow accumulation across Vestfonna. Altitude was found to be the only
significant spatial parameter for controlling snow accumulation across the ice cap.

Based on 1961–2005 observed winter precipitation data in Northeast China, the temporal and spatial variations of snow concentration degree (SCD) and snow concentration period (SCP), together with the circulation characteristics when
In this work tree rings were used to investigate a disruptive snow avalanche which occurred in 2001 in Val Mala in the Italian Alps. Comparison of tree reaction in surviving plants along the flow path and vegetation on the border showed i
Effect of snow amount on runoff, soil loss and suspended sediment during periods of snowmelt in southern West Siberia

Surface runoff, soil loss, suspended sediment concentration (SSC), texture of eroded soils and suspended sediment were determined on slightly eroded chernozems (mouldboard fall-ploughed) during years with different amounts of snow in three areas
of southern West Siberia (Predsalairye, Priobye and Kuznetsk hollow). These areas have different geomorphological and climatic characteristics and soils. Observations were made from 1969 to 2007. Soil losses in high-snow and very high-snow years varied from
Analysis of forest damage caused by the snow and ice chaos along a transect across southern China in spring 2008

An abrupt ice and snow storm disaster which occurred in the spring of 2008 severely destroyed forests over a surprisingly large portion of southern China. A transect crossing Jinggang Mountain-Jitai Basin-Yushan Mountain-Wuyi Mountain was selected

Sulfur and carbon isotopes within atmospheric, surface and ground water, snow and ice as indicators of the origin of tabular ground ice in the Russian Arctic
structure between TGI and atmospheric and continental moisture. TGI and its enclosing deposits have a heavier isotopic composition of sulfur and carbon than buried snow and glacial ice. This is considered to be evidence of an essential contribution of marine

Two types of landforms attributed to the geomorphological effects of long-lasting snow accumulations, snowpatch hollows and pronival ramparts, were studied in the Krkonoše Mountains, Czech Republic. Factors influencing the distribution
