Assessment of spring snow cover duration variability over northern Canada from satellite datasets
Remote Sensing of Environment, 2007Abstract Variability in northern hemisphere (NH) spring and summer snow extent is strongly influenced by snow cover duration (SCD) across the Canadian Arctic. In order to assess the accuracy with which satellite-derived snow extent datasets capture the dynamic melt period (1 April–31 July), SCD datasets derived from the weekly NOAA snow chart record (

RECENT CHANGES IN THE SNOW COVER DURATION IN BULGARIA � PRELIMINARY RESULTS
SGEM International Multidisciplinary Scientific GeoConference� EXPO ProceedingsSnow cover is an indicator of the fluctuating climate, resulting from the change in the regime of winter precipitations and air temperatures. Our previous studies have revealed significant decreasing of the seasonal snow cover maxima and the precipitation amounts in the highest mountainous regions of Bulgaria, which is however not so strong at lower ...

Spring snow cover duration and tundra greenness in the Lena Delta, Siberia
2022The Lena Delta in Siberia is the largest delta in the Arctic and as a snow-dominated ecosystem particularly vulnerable to climate change. Using the two decades of MODerate resolution Imaging Spectroradiometer satellite acquisitions, this study investigates interannual and spatial variability of snow-cover duration and summer vegetation vitality in the ...

Changes in climatic forcings on the Mediterranean area are foreseen by many global and regional models. Long-term temperature variations are expected to affect snow dynamics, thus impacting on the timing of the hydrologic response in Alpine catchments.

GIS-based modelling of spatial pattern of snow cover duration in an alpine area
Ecological Modelling, 2001Snow cover duration patterns of an alpine hillslope (approximately 2 km 2 ) were derived using daily terrestrial photographic remote sensing. We have developed a suite of quantitative models in order to investigate the relative controls of topographic factors, the degree of non-linearity, the effect of seasonal differences and a possible influence of ...

Snow Cover Duration in Relation to Topography in the Loetschental, Switzerland
2009In high mountain environments the spatial distribution of seasonal snow cover depends decisively on topography. Yearly repeated snow cover patterns during snow melt clearly indicate the impact of topography and influence significantly ecological and geomorphological patterns, as well as hydrological and climatic processes.

Small, self‐recording temperature sensors can be deployed quickly and inexpensively to monitor spatial and temporal patterns of snow accumulation and melt in complex environments. Burying these sensors slightly below the soil surface provides a record of the presence or absence of snow cover because near‐surface soil temperatures only experience ...

The snow cover occurrence index (SCOI), deffned as the ratio of the number of times that a pixel is classiffed as snow to the number of times that the pixel is observed in optical remote sensing data over a given year, can effectively mitigate the inffuence of clouds and holds great potential for extracting the annual snow duration and glacier extent ...

The production and use of artificial snow has become necessary in most ski centres in Europe. The lack of snow creates problems in ski centres that were built without the prior valuation of natural factors. The survey covered winter tourist centres in Serbia, which are facing problems due to the shortening of the tourist season caused by the lack of ...
