Temporal changes in chemical stratigraphy of snow cover

Spatio-temporal analysis of snow cover in Iran based on topographic characteristics

Investigation of snow cover changes affected by climate change In North West of Iran

 In this study in order to monitor snow cover, the Moderate Resolution Imaging Spectroradiometer (MODIS) optical images were used, while for detection of snow covered areas, the  snow index-NDSI, was applied. The results showed - according to the climatic conditions of the region- during the following months: December, January, February and March, most of the area is covered by snow and the max...

Spatial-temporal Patterns of Snow Cover in Western Canada

Snow cover is often measured as snow water equivalent (SWE), which refers to the amount of water stored in a snow-pack that would be available upon melting. Snow cover and SWE represent the source of local snow melt release, and are sensitive to regional and global atmospheric circulation, and changes in climate. Monitoring SWE using satellite-based passive microwave radiometry has provided nea...

Snow Cover

Snow cover is a layer of snow on the earth’s surface, which is mainly results from snowfalls. The snow cover can be temporary, when a snow melts during several hours or days after its formation, and it can be stable, when it remains for the whole winter or with short interruptions. The snow cover formation on the globe is determined (conditioned) by the geographical zonality, surface relief, an...

Multi-sensor/multi-temporal Approaches for Snow Cover Area Monitoring

The overall idea behind the work presented is to combine the use of optical and SAR sensors and utilise the best features of each sensor when possible in order to map snow cover area (SCA) more frequently and with better spatial coverage than would otherwise be possible. Optical remote sensing sensors are able to map snow cover quite accurately, but are limited by clouds. SAR sensors penetrate ...
